before webhook processes +- Files: `app/checkout/success/page.tsx` (redirect handler), `app/api/webhooks/stripe/route.ts` (webhook) +- Workaround: Stripe webhook eventually updates status (self-heals)

It operates on the `valid_anchors` DataFrame produced by Phase 21's `MultiExperimentIndex` and yields lists of integer indices consumed by `__getitems__()` in the downstream dataset (Phase 24). The sampler lives in `packages/viscy-data/src/viscy_data/` as a reusable utility. + +The core challenge is composing three independent sampling axes -- experiment restriction, condition balancing, and temporal enrichment -- into a single `__iter__` method that yields batch-sized index lists. Each axis progressively narrows the candidate pool for a batch. DDP support requires `set_epoch()` for deterministic shuffling and rank-aware index partitioning that composes with the existing `ShardedDistributedSampler` pattern. + +This is a well-understood problem domain. PyTorch's `Sampler[list[int]]` protocol is simple (`__iter__` yielding `list[int]`, `__len__`), and the `batch_sampler=` kwarg to `DataLoader`/`ThreadDataLoader` handles integration. The main complexity is the sampling logic itself: picking experiments, balancing conditions within experiments, and concentrating around temporal windows -- all while maintaining deterministic behavior across DDP ranks. + +**Primary recommendation:** Implement `FlexibleBatchSampler` as a `Sampler[list[int]]` subclass using a cascade approach: (1) pick experiment, (2) filter by condition quotas, (3) filter by temporal window, (4) sample indices. Use numpy RNG seeded by `epoch + seed` for DDP determinism. Do NOT hand-roll DDP sharding -- compose with the existing `ShardedDistributedSampler` or embed rank-aware slicing directly. + +## Standard Stack + +### Core +| Library | Version | Purpose | Why Standard | +|---------|---------|---------|--------------| +| torch | 2.x (installed) | `Sampler[list[int]]` base class, `Generator` for deterministic RNG | PyTorch's own sampler protocol | +| numpy | 1.x/2.x (installed) | `np.random.Generator` for seeded sampling, array operations | Faster than pandas for index manipulation | +| pandas | 2.x (installed) | DataFrame operations for groupby filtering | valid_anchors is a DataFrame | + +### Supporting +| Library | Version | Purpose | When to Use | +|---------|---------|---------|-------------| +| monai | (installed) | ThreadDataLoader accepts `batch_sampler=` via `**kwargs` passthrough | DataModule wiring in Phase 24 | + +### Alternatives Considered +| Instead of | Could Use | Tradeoff | +|------------|-----------|----------| +| Custom FlexibleBatchSampler | pytorch_metric_learning HierarchicalSampler | PML's sampler uses 2-level hierarchy (super_label/label); our 3-axis composition (experiment/condition/temporal) does not fit.

Each rank then takes every Nth batch (interleaved). This is simpler than trying to partition indices across ranks before batch construction, which would break experiment-aware constraints. + +### Pattern 3: Pre-computed Group Indices + +**What:** At `__init__` time, pre-compute per-experiment and per-condition index arrays from the valid_anchors DataFrame. Avoid repeated groupby during iteration. +**When to use:** Always. The valid_anchors DataFrame is immutable between epochs. + +```python +# Source: MultiExperimentIndex already provides experiment_groups and +# condition_groups, but FlexibleBatchSampler operates on valid_anchors +# (which has its own index space after reset_index(drop=True)) + +def _precompute_groups(self): + """Build lookup tables from valid_anchors columns.""" + self._experiment_indices = {} + for exp_name, group in self.valid_anchors.groupby("experiment"): + self._experiment_indices[exp_name] = group.index.to_numpy() + + self._condition_indices = {} + for cond, group in self.valid_anchors.groupby("condition"): + self._condition_indices[cond] = group.index.to_numpy() + + # Cross-index: per-experiment, per-condition + self._exp_cond_indices = {} + for (exp, cond), group in self.valid_anchors.groupby(["experiment", "condition"]): + self._exp_cond_indices[(exp, cond)] = group.index.to_numpy() +``` + +### Pattern 4: Temporal Enrichment with Focal Window + +**What:** Concentrate a fraction of the batch around a focal HPI, with the rest drawn globally. +**When to use:** When `temporal_enrichment=True`. + +```python +# Source: CONCORD (Zhu et al. Nature Biotech 2026) temporal concentration strategy + +def _enrich_temporal(self, pool: np.ndarray, rng: np.random.Generator) -> np.ndarray: + """Concentrate pool around a randomly chosen focal HPI.""" + hpi_values = self.valid_anchors.loc[pool, "hours_post_infection"].values + + # Pick focal HPI from existing values + focal_hpi = rng.choice(np.unique(hpi_values)) + + # Split pool into focal window and global + in_window = np.abs(hpi_values - focal_hpi) <= self.temporal_window_hours + focal_pool = pool[in_window] + global_pool = pool[~in_window] + + # Determine counts + n_global = int(self.batch_size * self.temporal_global_fraction) + n_focal = self.batch_size - n_global + + # Sample from each + focal_samples = rng.choice(focal_pool, size=min(n_focal, len(focal_pool)), replace=len(focal_pool) < n_focal) + global_samples = rng.choice(global_pool, size=min(n_global, len(global_pool)), replace=len(global_pool) < n_global) + + return np.concatenate([focal_samples, global_samples]) +``` + +### Anti-Patterns to Avoid + +- **Modifying valid_anchors during iteration:** The DataFrame is shared state. Never mutate it. All filtering should use boolean masks or index arrays. +- **Using pandas operations in the hot loop:** `groupby` and `loc` in `__iter__` are slow. Pre-compute index arrays at `__init__` time. +- **Global numpy random state:** PML samplers use `np.random.shuffle()` (global state) which is not DDP-safe. Always use `np.random.Generator` with explicit seed. +- **Coupling sampler to dataset:** The sampler should only know about index metadata (experiment, condition, HPI), never about image data or Position objects. +- **Trying to use batch_sampler AND sampler simultaneously:** PyTorch DataLoader raises ValueError if both are specified. When using `batch_sampler=`, do NOT pass `batch_size`, `shuffle`, `sampler`, or `drop_last`. + +## Don't Hand-Roll + +| Problem | Don't Build | Use Instead | Why | +|---------|-------------|-------------|-----| +| DDP index partitioning | Custom shard logic | Interleaved batch assignment (rank slicing) | Edge cases with uneven batches, padding, drop_last | +| Seeded RNG | `random.seed()` / `np.random.seed()` | `np.random.default_rng(seed)` | Thread-safe, no global state pollution, DDP-compatible | +| Weighted random selection | Manual probability computation | `rng.choice(a, p=weights)` | NumPy handles normalization, edge cases | +| DataFrame group indices | Repeated `df[df["col"]==val].index` | Pre-computed dict from `groupby` at init | O(1) lookup vs O(n) scan per batch | + +**Key insight:** The sampling logic itself is custom (no library provides this exact 3-axis composition), but all the building blocks (seeded RNG, weighted choice, index arrays) are standard numpy operations. The only truly custom code is the cascade logic in `_build_one_batch`. + +## Common Pitfalls + +### Pitfall 1: Non-deterministic DDP batches +**What goes wrong:** Different ranks generate different batches, leading to gradient desync and training divergence. +**Why it happens:** RNG not seeded identically across ranks, or `set_epoch()` not called. +**How to avoid:** Use `seed + epoch` as RNG seed. All ranks generate the same full batch list, then each takes its interleaved slice. Verify with a test that checks `set_epoch(0)` on rank 0 and rank 1 produce disjoint but collectively exhaustive batches. +**Warning signs:** NaN losses, validation metrics diverge between ranks, training hangs at gradient sync. + +### Pitfall 2: Small experiment/condition groups cause replacement sampling +**What goes wrong:** An experiment or condition has fewer cells than `batch_size`, requiring sampling with replacement, which duplicates samples. +**Why it happens:** Unbalanced datasets (e.g., 20 infected cells but batch_size=128). +**How to avoid:** Document the constraint: `batch_size` should not exceed the smallest experiment-condition group. Add a warning in `__init__` if any group is smaller than batch_size. Fall back to replacement sampling with a logged warning rather than crashing. +**Warning signs:** Training loss plateaus early, effective batch diversity is low. + +### Pitfall 3: Temporal enrichment starves rare timepoints +**What goes wrong:** With a narrow temporal window, cells at the edges of the HPI range are never sampled as focal cells, and the global fraction is too small to include them. +**Why it happens:** `temporal_window_hours` is too narrow, or `temporal_global_fraction` is too low. +**How to avoid:** Default `temporal_global_fraction=0.3` ensures 30% of each batch comes from all timepoints. Focal HPI is chosen uniformly from available HPIs, not weighted. +**Warning signs:** Embeddings cluster only by time, not by biological state. + +### Pitfall 4: batch_sampler + ThreadDataLoader kwargs conflict +**What goes wrong:** Passing `batch_sampler=` along with `batch_size=`, `shuffle=`, or `drop_last=` to DataLoader raises ValueError. +**Why it happens:** PyTorch enforces mutual exclusivity between `batch_sampler` and these kwargs. +**How to avoid:** When using FlexibleBatchSampler, the DataModule (Phase 24) must NOT pass batch_size/shuffle/drop_last to ThreadDataLoader. Only pass `batch_sampler=`, `num_workers=`, `collate_fn=`, etc. +**Warning signs:** ValueError at DataLoader construction time (easy to catch in tests). + +### Pitfall 5: __len__ mismatch with actual iteration count +**What goes wrong:** DataLoader expects `__len__` to return the correct number of batches for progress bars and epoch completion. If `__len__` disagrees with actual `__iter__` count, training loop may hang or skip data. +**Why it happens:** `__len__` computed from total indices / batch_size, but actual batches depend on per-experiment constraints that may yield fewer batches. +**How to avoid:** Compute `__len__` as `total_batches // num_replicas` where `total_batches` is the number of batches that `__iter__` will actually yield. Pre-compute this in `__init__` based on the total number of valid anchors and batch size. +**Warning signs:** Progress bar stuck at 99%, training epoch never completes, or ends prematurely. + +### Pitfall 6: valid_anchors index vs tracks index confusion +**What goes wrong:** valid_anchors has `reset_index(drop=True)`, giving it indices 0..N-1. The sampler yields these indices. But if someone confuses them with tracks indices (which may be a superset), wrong cells get loaded. +**Why it happens:** Two DataFrames (tracks, valid_anchors) with different index spaces. +**How to avoid:** The sampler operates ONLY on valid_anchors indices. Document this clearly. The dataset's `__getitems__` also uses `self.valid_anchors.iloc[indices]`, matching the sampler's output. +**Warning signs:** KeyError or IndexError when dataset tries to look up a sampler-provided index. + +## Code Examples + +### FlexibleBatchSampler skeleton (verified pattern from PyTorch Sampler protocol) + +```python +# Source: torch.utils.data.sampler.Sampler protocol + DistributedSampler pattern +from __future__ import annotations + +import math +from collections.abc import Iterator + +import numpy as np +import pandas as pd +from torch.utils.data import Sampler + + +class FlexibleBatchSampler(Sampler[list[int]]): + """Composable batch sampler with experiment-aware, condition-balanced, + and temporal enrichment axes. + + Yields lists of integer indices into a valid_anchors DataFrame. + """ + + def __init__( + self, + valid_anchors: pd.DataFrame, + batch_size: int = 128, + #

RandomState is legacy. +- PML's `NUMPY_RANDOM` global: Not DDP-safe. Avoid. + +## Open Questions + +1. **Experiment weighting strategy** + - What we know: `experiment_weights` allows manual per-experiment probabilities for experiment selection. + - What's unclear: Should the default be uniform across experiments, or proportional to the number of valid anchors per experiment? + - Recommendation: Default to proportional (larger experiments sampled more often) with uniform as an explicit option. This prevents tiny experiments from dominating batch counts. Planner can decide. + +2. **Condition ratio when more than 2 conditions exist** + - What we know: Current requirements assume binary (infected/uninfected). `condition_ratio` dict supports N conditions. + - What's unclear: What if an experiment has 3+ conditions (e.g., "uninfected", "low_moi", "high_moi")? + - Recommendation: Support arbitrary condition counts. Default to equal ratios. The `condition_ratio` dict allows user override. + +3. **Temporal enrichment focal HPI selection** + - What we know: A focal HPI is chosen per batch, and cells within `temporal_window_hours` are concentrated. + - What's unclear: Should focal HPI be chosen from the union of all HPIs in the experiment, or per-batch randomly? + - Recommendation: Per-batch random selection from unique HPIs within the chosen experiment. This ensures all timepoints get exposure across batches. + +4. **How `__len__` interacts with Lightning's progress bar** + - What we know: Lightning calls `len(dataloader)` for progress bars. DataLoader delegates to `len(batch_sampler)`. + - What's unclear: If the sampler's actual iteration count varies slightly from `__len__` (due to rounding in condition balance), does Lightning handle this gracefully? + - Recommendation: Make `__len__` a conservative lower bound (floor division). Lightning handles `__iter__` exhaustion gracefully. + +5. **Interaction with `ShardedDistributedSampler` vs embedded DDP** + - What we know: STATE.md says "DDP via FlexibleBatchSampler + ShardedDistributedSampler composition". But `batch_sampler=` and `sampler=` are mutually exclusive in DataLoader. + - What's unclear: Does "composition" mean embedding DDP logic inside FlexibleBatchSampler, or wrapping? + - Recommendation: Embed DDP logic directly in FlexibleBatchSampler (num_replicas, rank, set_epoch). Do NOT try to compose with ShardedDistributedSampler as a separate sampler -- DataLoader forbids this. The "composition" means FlexibleBatchSampler follows the same pattern (set_epoch, rank-aware slicing) rather than literally wrapping ShardedDistributedSampler. + +## Upstream Dependencies (Phase 21 API Surface) + +### valid_anchors DataFrame Schema + +The FlexibleBatchSampler receives `valid_anchors` which is a `pd.DataFrame` with `reset_index(drop=True)` (integer index 0..N-1).

An intentional deferral -- Phase 24 (MultiExperimentDataModule) is explicitly described in ROADMAP as the phase that wires ChannelDropout.

These are consumed by `on_after_batch_transfer` before the engine's `training_step` receives the batch. The engine only reads `batch["anchor"]` and `batch["positive"]`, so the batch format is fully compatible without engine changes. + +2. **Division lineage:** `_reconstruct_lineage` in `index.py` sets each track's `lineage_id` to its root ancestor's `global_track_id` via parent graph traversal. Daughters share the parent's `lineage_id`. The dataset's `_build_lineage_lookup` indexes by `(experiment, lineage_id) -> {t: [row_indices]}`, enabling O(1) positive lookup that naturally crosses division boundaries. + +3. **collate_fn=lambda x: x:** Both train and val dataloaders use identity collation because `__getitems__` returns an already-batched dict (not a list of individual samples). `FlexibleBatchSampler` provides batched indices. + +4. **hcl_beta on DataModule:** Stored for Lightning CLI YAML discoverability but not functionally used by the DataModule. The actual `NTXentHCL` is configured on `ContrastiveModule`.

Introducing sub-packages (e.g., `viscy_data/modules/`, `viscy_data/datasets/`) would split tightly coupled code across directories without meaningful encapsulation. The flat layout mirrors the original `viscy/data/` structure, minimizing migration risk. - -**Why `_utils.py` and `_typing.py` (underscore prefix):** These are internal modules. The underscore communicates they are not part of the public API. Users import from `viscy_data` (the package), not from `viscy_data._utils`. - -**Why split `combined.py` into `combined.py` + `concat.py`:** The current `combined.py` contains two distinct patterns: -1. `CombinedDataModule` -- wraps data modules using Lightning's `CombinedLoader` for multi-source training -2. `ConcatDataModule` + `BatchedConcatDataModule` + `CachedConcatDataModule` + `BatchedConcatDataset` -- concatenation-based combining using `torch.utils.data.ConcatDataset` +### Component Boundaries -These serve different purposes and have different dependency profiles. `CombinedDataModule` depends on `hcs._collate_samples` (moving to `_utils.py`). The concat modules have their own inheritance hierarchy (`ConcatDataModule <|-- BatchedConcatDataModule`).

MONAI's `CenterSpatialCropd` (non-batched) works on individual channel tensors within the dict. The key insight is that `BatchedCenterSpatialCropd` was only needed because the original code path was applying the crop to a batch dimension -- but `_transform_channel_wise` already handles the batch by operating per-channel. The standard MONAI crop suffices here. - -**Verification needed during implementation:** Run the triplet tests with `z_window_size` parametrization to confirm output shapes match. - -## Optional Dependency Groups Structure - -### Design - -The package has three tiers of dependencies: - -**Tier 1 - Required (always installed):** -- `torch` (core tensor ops) -- `lightning` (LightningDataModule base class) -- `numpy` (array conversion) -- `iohub` (OME-Zarr I/O -- used by 8 of 13 modules) -- `monai` (transforms, data utilities -- used by 10 of 13 modules) -- `zarr` (direct zarr operations in hcs.py caching) -- `imageio` (imread in MaskTestDataset) +### Pattern 3: Workspace Dependencies via Sources -**Tier 2 - Optional dependency groups (install with extras):** +**What:** Inter-package dependencies declared with `workspace = true`. -| Group Name | Dependencies | Required By | -|------------|-------------|-------------| -| `triplet` | `tensorstore`, `pandas` | `triplet.py`, `cell_classification.py` | -| `livecell` | `pycocotools`, `tifffile`, `torchvision` | `livecell.py` | -| `mmap` | `tensordict` | `mmap_cache.py` | -| `all` | All of the above | Everything | +**When:** Package A depends on Package B, both in workspace. -**Tier 3 - Development (dependency groups, not optional-dependencies):** -- `pytest`, `pytest-cov` - -### pyproject.toml Structure +**Why:** Ensures editable installs during development, proper resolution during publish. +**Configuration:** ```toml +# packages/viscy-data/pyproject.toml [project] -name = "viscy-data" -dynamic = ["version"] -dependencies = [ - "iohub>=0.2", - "imageio>=2.35", - "lightning>=2.5", - "monai>=1.5.2", - "numpy>=2.4.1", - "torch>=2.10", - "zarr>=3", -] - -[project.optional-dependencies] -triplet = ["tensorstore>=0.1.68", "pandas>=2.2"] -livecell = ["pycocotools>=2.0.8", "tifffile>=2024.1", "torchvision>=0.20"] -mmap = ["tensordict>=0.6"] -all = [ - "viscy-data[triplet]", - "viscy-data[livecell]", - "viscy-data[mmap]", -] - -[dependency-groups] -dev = [{ include-group = "test" }] -test = ["pytest>=9.0.2", "pytest-cov>=7"] -``` - -### Lazy Import Strategy - -Modules with optional dependencies must use lazy imports with clear error messages: - -```python -# In triplet.py: -def _setup_tensorstore(): - try: - import tensorstore as ts - except ImportError: - raise ImportError( - "tensorstore is required for TripletDataset.

But if the guard is at the module level and the import is used inside a class method, the error only surfaces when that specific code path is exercised -- potentially deep inside a training loop after hours of preprocessing. Worse: if you guard the import at module level with a sentinel (`HAS_TENSORSTORE = False`) but forget to check the sentinel before using the library in a method, you get `NameError: name 'tensorstore' is not defined` instead of a helpful message. +**What goes wrong:** uv workspaces enforce a single `requires-python` for the entire workspace, computed as the intersection of all members' values. If one package needs Python 3.11+ and another needs 3.12+, the workspace becomes 3.12+ only. -**Why it happens:** -During extraction, developers convert `import tensorstore` to a guarded import but don't systematically audit every usage site. The module has 13 files; it's easy to miss a call site in a nested helper. The triplet.py module in particular uses tensorstore inside a dataset `__getitem__` which is called by DataLoader workers -- the error appears in a worker subprocess stack trace, obscuring the real cause. - -**How to avoid:** -1. Use a centralized lazy import pattern in `_imports.py`: - ```python - def _require_tensorstore(): - try: - import tensorstore - return tensorstore - except ImportError: - raise ImportError( - "tensorstore is required for TripletDataModule. " - "Install it with: pip install viscy-data[triplet]" - ) from None - ``` -2. Call `_require_tensorstore()` at the top of every method that uses it, not at module level. -3. Add a test for each optional-dep module that verifies the ImportError message when the dep is missing. Use `pytest.importorskip` in tests, but also test the error path. -4. In CI, run one test job with only base deps installed (no extras) to catch unguarded imports. - -**Warning signs:** -- Any `import X` at module top-level for an optional dependency -- Tests that always install `[all]` extras -- they never catch missing-dep errors -- `NameError` in DataLoader worker processes during training - -**Phase to address:** -Package scaffolding phase (pyproject.toml + `_imports.py` helper). Verify in CI phase with a "minimal deps" test job. +**Why it happens:** uv resolves dependencies for the entire workspace into a single lockfile. Different Python version constraints would make this impossible. + +**Consequences:** +- Cannot test viscy-transforms on Python 3.11 if any future package requires 3.12 +- Downstream users on 3.11 may be unable to install individual packages even if they'd work standalone + +**Prevention:** +- Decide on the lowest Python version the workspace will support upfront (3.11 for VisCy) +- Document this constraint in workspace root pyproject.toml +- All packages must use `requires-python = ">=3.11"` (or the agreed floor) + +**Detection:** `uv lock` will fail with Python constraint conflicts during resolution. + +**Phase:** Address in Phase 1 (workspace scaffolding). + +**Confidence:** HIGH (verified in [uv workspaces documentation](https://docs.astral.sh/uv/concepts/projects/workspaces/)) --- -### Pitfall 2: Manager().dict() Shared Cache Is Not Picklable Across spawn Contexts +### Pitfall 2: Conflicting Dependencies Between Workspace Members -**What goes wrong:** -`CachedOmeZarrDataset` uses `multiprocessing.Manager().dict()` as a shared cache across DataLoader workers. This works with PyTorch's default `fork` start method on Linux, but fails on macOS (default `spawn`) and Windows (only `spawn`). The `Manager` proxy objects must be passed to workers via pickling, and depending on when the Manager is created relative to DataLoader fork/spawn, you get either: (a) `RuntimeError: cannot pickle 'weakref' object` or (b) a silently separate cache per worker (defeating the purpose). +**What goes wrong:** All workspace members share a single lockfile. If viscy-transforms needs `numpy<2` and a future package needs `numpy>=2`, resolution fails. -**Why it happens:** -The original code was developed and tested on Linux HPC clusters where `fork` is the default. The extraction needs cross-platform CI (Ubuntu, macOS, Windows per existing test.yml matrix). The `spawn` start method creates fresh Python processes that must pickle everything passed to them. `Manager().dict()` proxy objects work across `fork` boundaries but behave differently under `spawn`. - -**How to avoid:** -1. Create the `Manager` in `setup()` (Lightning hook), not in `__init__`. Lightning's `setup()` runs after the Trainer has configured the multiprocessing context. -2. Store the manager reference on `self` so it persists for the lifetime of the DataModule. -3. Test with `mp_start_method="spawn"` explicitly in at least one CI configuration: - ```python - @pytest.fixture - def spawn_trainer(): - return Trainer(accelerator="cpu", devices=1, - strategy=SingleDeviceStrategy(device="cpu")) - ``` -4. Consider replacing `Manager().dict()` with `torch.multiprocessing.Queue` or a file-based cache (memory-mapped array via tensordict's `MemoryMappedTensor`) which is already used in `mmap_cache.py`. -5. Document that `num_workers=0` avoids the issue entirely (useful for debugging). - -**Warning signs:** -- Tests pass on Linux but fail on macOS/Windows CI -- `pickle` or `weakref` errors in DataLoader worker stack traces -- Cache hit rate is 0% despite repeated access to same volumes - -**Phase to address:** -Code migration phase. Must be addressed before CI matrix runs on macOS/Windows. +**Why it happens:** uv workspaces assume all packages can coexist in one environment. This is by design for consistency but breaks when packages have incompatible dependency trees. + +**Consequences:** +- Cannot lock the workspace +- Must either downgrade the newer package's requirements or remove the conflicting package from the workspace + +**Prevention:** +- Survey dependency constraints before adding packages to workspace +- For PyTorch/NumPy heavy scientific packages, pin compatible version ranges early +- Use `[tool.uv.conflicts]` to declare mutually exclusive extras/groups if needed +- Consider path dependencies instead of workspace membership for packages with known conflicts + +**Detection:** `uv lock` fails with dependency resolution errors. + +**Phase:** Address during each package extraction (ongoing vigilance). + +**Confidence:** HIGH (verified in [uv resolution docs](https://docs.astral.sh/uv/concepts/resolution/)) --- -### Pitfall 3: Base Class Extraction Creates Hidden Import Cycles +### Pitfall 3: uv-dynamic-versioning Does Not Work with uv Build Backend -**What goes wrong:** -`HCSDataModule` is both a concrete DataModule (used directly for translation fine-tuning) and the base class for `TripletDataModule` and `CellDivisionTripletDataModule`. It contains shared utility methods like `_read_norm_meta()` and references to iohub types. When extracting shared utilities into `_utils.py`, developers often create circular imports: `hcs.py` imports from `_utils.py`, but `_utils.py` needs types defined in `_typing.py` which imports from something that imports from `hcs.py`. +**What goes wrong:** If you configure `build-backend = "uv"` instead of `build-backend = "hatchling.build"`, uv-dynamic-versioning silently fails or produces incorrect versions. -More subtly: if `_utils.py` imports `Sample` from `_typing.py`, and `hcs.py` imports from both `_utils.py` and `_typing.py`, the import order depends on which module is imported first. If `triplet.py` imports `hcs.py` before `_typing.py` is loaded, you get a partially initialized module. +**Why it happens:** uv-dynamic-versioning is a hatchling plugin. It requires hatchling as the build backend to function. -**Why it happens:** -The original `hcs.py` was a single module that served as both a concrete implementation and a utility library. The README.md explicitly notes this dual role: "_hcs.py serves as both a concrete data module AND a utility library_." Extracting utilities without carefully analyzing the import dependency graph creates cycles. - -**How to avoid:** -1. Map the complete import graph BEFORE moving any code. The dependency graph in `viscy/data/README.md` is the starting point, but also trace function-level dependencies. -2. Follow a strict layering rule: - ``` - _typing.py (types only, no imports from viscy_data) - | - _utils.py (imports only from _typing, stdlib, and external libs) - | - hcs.py (imports from _typing and _utils) - | - triplet.py (imports from _typing, _utils, and hcs) - ``` -3. Test the import order explicitly: `python -c "from viscy_data import TripletDataModule"` should work without importing `hcs` first. -4. Use `ruff` rule `I001` (isort) to keep imports consistent, but also add a custom test that verifies no circular imports exist. - -**Warning signs:** -- `ImportError: cannot import name 'X' from partially initialized module` -- Tests pass when run individually but fail when run as a suite (import order dependency) -- `AttributeError` on a module object (partially loaded module) - -**Phase to address:** -Code migration phase -- specifically the `_utils.py` extraction plan. +**Consequences:** +- Packages built with version `0.0.0` or missing version +- CI releases fail +- PyPI uploads rejected or have wrong version + +**Prevention:** +- Always use `build-backend = "hatchling.build"` when using uv-dynamic-versioning +- Never use `build-backend = "uv"` or `build-backend = "uv_build"` with this plugin +- Verify version in built wheel/sdist before publishing + +**Detection:** Run `uv build` and check the generated filename for correct version. + +**Phase:** Address in Phase 1 (build system setup). + +**Confidence:** HIGH (verified in [uv-dynamic-versioning README](https://github.com/ninoseki/uv-dynamic-versioning)) --- -### Pitfall 4: Optional Extras Create a 2^N CI Matrix Explosion +### Pitfall 4: Import Leakage Between Workspace Members -**What goes wrong:** -With 4 optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`), testing all combinations across 3 Python versions and 3 OS targets creates a massive matrix: (base + triplet + livecell + mmap + all) x 3 Python x 3 OS = 45 jobs. But some combinations are invalid (pycocotools doesn't build on Windows; tensorstore has limited arm64 support on macOS). The matrix either explodes in cost or has confusing include/exclude rules. +**What goes wrong:** Python has no dependency isolation. viscy-transforms can accidentally import from viscy-data even if it doesn't declare that dependency, because all workspace members are installed in the same environment. -**Why it happens:** -viscy-transforms had no optional dependencies -- all deps were required. viscy-data is the first package with optional extras. The existing CI (`test.yml`) uses a simple 3x3 matrix. Naively extending it for extras creates an unmaintainable workflow. - -**How to avoid:** -1. Do NOT test all combinations. Use this strategy: - - **Base job** (no extras): 3 Python x 3 OS = 9 jobs. Tests only modules that work with base deps. - - **Full extras job** (`[all]`): 1 Python (3.12) x 1 OS (ubuntu-latest) = 1 job. Tests everything. - - **Per-extra smoke test**: 1 Python x 1 OS per extra = 3 jobs. Tests that the extra installs correctly. -2. Use pytest markers to skip tests when optional deps are missing: - ```python - tensorstore = pytest.importorskip("tensorstore") - ``` -3. Exclude known-broken combinations using the GitHub Actions matrix `exclude` key: - ```yaml - exclude: - - os: windows-latest - extras: livecell # pycocotools build fails on Windows - ``` -4. For the `[all]` extra, document that it may not install on all platforms. This is acceptable -- scientific Python packages routinely have platform limitations. - -**Warning signs:** -- CI takes >30 minutes due to matrix size -- Frequent red CI from platform-specific build failures in optional deps -- Maintainers start ignoring CI failures ("oh that's just the Windows pycocotools thing") - -**Phase to address:** -CI phase. Design the matrix before writing the workflow file. +**Why it happens:** `uv sync` installs all workspace members as editable. They share a virtual environment. Python doesn't enforce import boundaries. + +**Consequences:** +- Package works in monorepo but fails when installed standalone +- CI passes but users report `ModuleNotFoundError` +- Hidden coupling between packages + +**Prevention:** +- Run `uv sync --package viscy-transforms` and test in isolation +- CI should test each package independently, not just the whole workspace +- Consider running `uv pip install viscy-transforms --no-deps` and verifying imports work with only declared dependencies + +**Detection:** Install package in fresh venv outside workspace and run tests. + +**Phase:** Address in Phase 1 (CI setup) and validate with each extraction. + +**Confidence:** HIGH (explicitly documented in [uv workspaces docs](https://docs.astral.sh/uv/concepts/projects/workspaces/)) --- -### Pitfall 5: pycocotools Build Failure Blocks Entire CI on Windows +### Pitfall 5: Entry Points Lost During Migration -**What goes wrong:** -`pycocotools` requires a C compiler to build from source. On Ubuntu, `gcc` is available by default. On macOS, `clang` via Xcode Command Line Tools. On Windows, there is no default C compiler -- users need Visual Studio Build Tools installed. If the CI matrix includes Windows + `[livecell]` or `[all]`, the job fails at pip install time, not at test time, with a cryptic compilation error. +**What goes wrong:** Console script entry points (`viscy = "viscy.cli:main"`) stop working after migration from setuptools to hatchling. **Why it happens:** -pycocotools does not always have pre-built wheels for all platform/Python version combinations. When a wheel is missing, pip falls back to building from source, which requires a C compiler. Windows GitHub Actions runners have MSVC available, but the environment may not be configured correctly for all Python versions. - -**How to avoid:** -1. Use the `pycocotools` package from conda-forge or the `pycocotools-windows` fork if targeting Windows. -2. Better: mark `[livecell]` as Linux/macOS only in documentation. LiveCell is a research dataset used primarily on HPC Linux clusters. -3. In CI, exclude the livecell extra from Windows: - ```yaml - exclude: - - os: windows-latest - python-version: "3.11" # if no wheel available - ``` -4. Alternatively, use `cython` + build isolation: `pip install pycocotools --no-build-isolation` can sometimes help, but this is fragile. -5. Pin pycocotools to a version that has wheels for your target platforms. Check PyPI for available wheels before pinning. - -**Warning signs:** -- `error: Microsoft Visual C++ 14.0 or greater is required` in CI logs -- CI green on Ubuntu/macOS, red on Windows -- Intermittent failures when new Python versions lack pre-built wheels - -**Phase to address:** -Package scaffolding phase (dependency specification) + CI phase (matrix exclusions). +- Different configuration syntax between setuptools and hatchling +- Mixing `[project.scripts]` and `[options.entry_points]` in same file +- Forgetting to migrate entry points at all + +**Consequences:** +- `viscy` CLI command not found after install +- Users cannot invoke tools from command line + +**Prevention:** +- Explicitly audit all `[project.scripts]` and `[project.entry-points]` sections +- Test CLI commands work after migration: `uv run viscy --help` +- For VisCy: ensure `viscy = "viscy.cli:main"` is preserved in root package + +**Detection:** After install, run the CLI command and verify it works. + +**Phase:** Address when extracting any package with CLI entry points. + +**Confidence:** MEDIUM-HIGH (multiple reports in [setuptools issues](https://github.com/pypa/setuptools/issues/4153)) --- -### Pitfall 6: iohub API Coupling Creates Fragile Type Boundaries +## Moderate Pitfalls -**What goes wrong:** -The data modules use iohub's `Position`, `Plate`, `Well`, and `ImageArray` types extensively -- not just for I/O, but as type annotations on public methods and in constructor signatures. If iohub releases a breaking change (e.g., renaming `Position` to `FOV`, or changing the `ImageArray` interface), every data module breaks simultaneously. More immediately: if the viscy-data pyproject.toml pins `iohub>=0.X` but a user has `iohub==0.X-1`, they get confusing `AttributeError`s instead of a clean version conflict. +Mistakes that cause delays, confusion, or technical debt (but are recoverable). -**Why it happens:** -iohub is developed by the same team (CZ Biohub), so API stability was implicitly assumed. The tight coupling is intentional -- these types ARE the domain model. But as a separately packaged library, iohub's release cycle is now decoupled from viscy-data's. - -**How to avoid:** -1. Pin iohub with a minimum version that has the API you depend on: `iohub>=0.2.0` (or whatever version stabilized the `Position`/`Plate` API). -2. DO NOT pin an upper bound (`iohub<1.0`) -- this causes resolver hell for users. Trust semantic versioning. -3. Add an integration test that imports all iohub types used by viscy-data and verifies they have the expected attributes. This catches API drift early: - ```python - def test_iohub_api_surface(): - from iohub.ngff import Position, Plate, ImageArray - assert hasattr(Position, "__getitem__") # etc. - ``` -4. Document which iohub version was tested against in the README. - -**Warning signs:** -- iohub release notes mention "breaking changes" or "renamed" -- Users report `AttributeError` on iohub objects -- `uv lock` resolves a newer iohub than was tested - -**Phase to address:** -Package scaffolding phase (dependency pinning). Integration test in test migration phase. +--- + +### Pitfall 6: Docker Build Inefficiency with Workspace Dependencies + +**What goes wrong:** Docker builds copy entire workspace for every package, causing massive cache invalidation. Any change to any package rebuilds all Docker images. + +**Why it happens:** uv requires workspace member files present to resolve dependencies. You can't just copy `uv.lock` and install third-party deps without the package sources. + +**Prevention:** +- Use `uv sync --frozen --package ` which resolves from lockfile alone (partially works) +- Structure Dockerfiles to copy minimal files first, then add sources +- Consider `--no-editable` flag when available for self-contained builds + +**Detection:** Docker build times remain high even for unrelated changes. + +**Phase:** Address in Phase 4 (CI/CD optimization) or defer to later milestone. + +**Confidence:** MEDIUM (discussed in [uv issue #6935](https://github.com/astral-sh/uv/issues/6935)) --- -### Pitfall 7: ThreadDataLoader from MONAI Breaks Isolation Testing +### Pitfall 7: IDE Workspace Recognition Failures -**What goes wrong:** -`TripletDataModule` uses `monai.data.ThreadDataLoader` instead of PyTorch's `DataLoader`. When running `uv sync --package viscy-data` for isolated testing, the test environment has MONAI installed (it's a required dep). But `ThreadDataLoader` has threading behavior that interacts badly with pytest's test isolation -- specifically, thread-local state can leak between tests, and `tensorstore`'s async I/O in threads can deadlock if the event loop is not properly managed. +**What goes wrong:** VS Code/PyCharm don't understand uv workspace structure. Pylance shows import errors for valid workspace dependencies. Auto-complete fails. -More specifically: `ThreadDataLoader` creates `ThreadPoolExecutor` workers instead of subprocess workers. These threads share the GIL and the process's memory space. If a test creates a `ThreadDataLoader` and doesn't explicitly shut it down, the threads persist into the next test, causing resource leaks and eventual `OSError: too many open files`. +**Why it happens:** IDEs look for standard Python project markers. uv workspaces use different conventions than Poetry/pip. -**Why it happens:** -`ThreadDataLoader` was chosen for DynaCLR/triplet because tensorstore performs async I/O that releases the GIL. Thread-based workers are more efficient than subprocess workers for GIL-releasing I/O. But this design choice has testing implications that aren't obvious until you run a full test suite. - -**How to avoid:** -1. Use pytest fixtures that explicitly create and tear down DataLoaders: - ```python - @pytest.fixture - def triplet_dataloader(triplet_datamodule): - triplet_datamodule.setup("fit") - loader = triplet_datamodule.train_dataloader() - yield loader - # Explicit cleanup - if hasattr(loader, '_executor'): - loader._executor.shutdown(wait=False) - ``` -2. Run triplet-related tests in a separate pytest session or mark them with `@pytest.mark.forked` (requires `pytest-forked`). -3. Set `num_workers=0` in test fixtures to avoid threading entirely. Reserve `num_workers>0` tests for integration/slow test marks. -4. Add resource leak detection: `pytest --tb=short -W error::ResourceWarning`. - -**Warning signs:** -- Tests hang indefinitely when run as a full suite but pass individually -- `OSError: [Errno 24] Too many open files` in CI -- Intermittent test failures ("flaky tests") that depend on test execution order - -**Phase to address:** -Test migration phase.

If the guard fails or is at module level, `import viscy_data` itself fails for users who only installed the base package without extras. +**What goes wrong:** If VisCy kept `viscy.transforms` as a namespace package allowing both old and new code to coexist, all packages sharing that namespace must use identical `__init__.py` files. -**Why it happens:** -viscy-transforms got away with eager re-exports because all its dependencies are required. viscy-data has optional deps that make eager re-exports dangerous. - -**How to avoid:** -1. Only re-export classes whose modules have no optional dependencies in `__init__.py`: - ```python - # viscy_data/__init__.py - from viscy_data.hcs import HCSDataModule, SlidingWindowDataset - from viscy_data.gpu_aug import GPUTransformDataModule - from viscy_data.combined import CombinedDataModule - from viscy_data.distributed import ShardedDistributedSampler - # Do NOT import from triplet, livecell, mmap_cache at top level - ``` -2. For optional-dep modules, use `__all__` and document the import path: - ```python - # Users must import explicitly: - # from viscy_data.triplet import TripletDataModule - ``` -3. Alternatively, use `__getattr__` for lazy module-level imports (PEP 562): - ```python - def __getattr__(name): - if name == "TripletDataModule": - from viscy_data.triplet import TripletDataModule - return TripletDataModule - raise AttributeError(f"module 'viscy_data' has no attribute {name}") - ``` - -**Warning signs:** -- `import viscy_data` fails on a fresh install without `[all]` -- Users report `ModuleNotFoundError: No module named 'tensorstore'` when they only wanted `HCSDataModule` - -**Phase to address:** -Package scaffolding phase (design `__init__.py` strategy before code migration). +**Why it happens:** Python's namespace package mechanism (pkgutil or pkg_resources style) requires consistency across all packages using the namespace. + +**Consequences:** +- Import failures +- "Namespace package breaks module imports" errors +- Partial imports work, others fail randomly + +**Prevention:** +- VisCy chose clean break approach (good decision) +- `from viscy_transforms import X` not `from viscy.transforms import X` +- No namespace packages, no coordination required + +**Detection:** Would manifest as inconsistent import errors. + +**Phase:** N/A for VisCy (already decided on clean break). + +**Confidence:** HIGH (documented in [Python Packaging Guide](https://packaging.python.org/en/latest/guides/packaging-namespace-packages/)) --- -### Pitfall 9: Zarr/iohub Test Fixtures Are Expensive and Non-Trivial +### Pitfall 10: Optional Dependencies Conflicting Across Groups -**What goes wrong:** -Data module tests require actual OME-Zarr stores with HCS plate structure (plates > wells > FOVs > images). Creating these fixtures is not trivial -- it requires iohub to write proper OME-Zarr metadata, multiple resolution levels, and channel metadata. If each test creates its own fixture, the test suite becomes extremely slow. If fixtures are shared (session-scoped), tests can interfere with each other through mutations. +**What goes wrong:** `viscy[dev]` includes `onnxruntime` but a future `viscy[gpu]` extra needs `onnxruntime-gpu`. These packages conflict and cannot be installed together. -Additionally, tensorstore tests need properly structured Zarr arrays, and livecell tests need COCO-format JSON annotations plus TIFF images. These are three different fixture ecosystems within one package. +**Why it happens:** PyPI packages can have mutually exclusive variants. uv resolves all extras together by default. -**Why it happens:** -viscy-transforms tests only needed tensor fixtures (easy: `torch.randn(1, 1, 32, 32)`). Data module tests need filesystem-backed fixtures with specific directory structures and metadata. This is a qualitative jump in fixture complexity. - -**How to avoid:** -1. Create a `conftest.py` with session-scoped, read-only fixtures: - ```python - @pytest.fixture(scope="session") - def ome_zarr_store(tmp_path_factory): - """Create a minimal HCS OME-Zarr store for testing.""" - store_path = tmp_path_factory.mktemp("data") / "test.zarr" - # Use iohub to create a proper HCS plate - from iohub.ngff import open_ome_zarr - with open_ome_zarr(store_path, layout="hcs", mode="w") as plate: - position = plate.create_position("A", "1", "0") - position.create_image("0", data=np.random.rand(1, 2, 5, 64, 64)) - return store_path - ``` -2. Use `tmp_path_factory` (session-scoped) not `tmp_path` (function-scoped) for expensive I/O fixtures. -3. Mark tests that need real I/O fixtures with `@pytest.mark.slow` and skip them in the fast CI job. -4. For livecell: create a minimal COCO JSON fixture as a Python dict, write it to a temp file. Do not download real LiveCell data in CI. -5. NEVER use real data paths in tests. The existing Hydra configs reference `/hpc/projects/...` paths that are HPC-specific. - -**Warning signs:** -- Test suite takes >5 minutes due to fixture creation -- Tests fail on CI but pass locally (missing data files) -- Flaky tests due to shared mutable fixtures - -**Phase to address:** -Test migration phase. Design fixture strategy BEFORE writing test files. +**Prevention:** +- Use `[tool.uv.conflicts]` to declare mutually exclusive extras: + ```toml + [tool.uv] + conflicts = [ + [ + { extra = "cpu" }, + { extra = "gpu" }, + ] + ] + ``` +- Document which extras can be combined +- Consider separate packages instead of conflicting extras + +**Detection:** `uv lock` fails when conflicting extras exist without conflict declaration. + +**Phase:** Address when defining extras for extracted packages. + +**Confidence:** HIGH (documented in [uv dependencies docs](https://docs.astral.sh/uv/concepts/projects/dependencies/)) --- -### Pitfall 10: Lightning CLI / Hydra Config Class Paths Break Silently +### Pitfall 11: CI Cache Explosion in Monorepos -**What goes wrong:** -Downstream training configs (Hydra YAML, Lightning CLI YAML) reference data modules by fully qualified class path: -```yaml -# Old path (broken after extraction) -data: - class_path: viscy.data.hcs.HCSDataModule +**What goes wrong:** Every PR creates its own cache copy of `.venv` and `~/.cache/uv`. GitHub Actions storage fills up. Build times remain slow despite caching. -# New path (correct) -data: - class_path: viscy_data.hcs.HCSDataModule -``` -The breakage is silent -- configs are just YAML files, so no linter or type checker catches the stale path. The error only appears when someone runs training, potentially weeks after the extraction. +**Why it happens:** Default cache key includes PR-specific identifiers. No shared baseline cache. -Hydra is explicitly out of scope per PROJECT.md, but Lightning CLI is used by the training pipelines. The existing Hydra output configs in `applications/dynacell/outputs/` show the config structure but don't reference class paths (they use nested config, not `_target_`). However, Lightning CLI configs DO use `class_path`. +**Prevention:** +- Use `uv cache prune --ci` before saving cache (removes pre-built wheels) +- Share cache across PRs using workflow-level cache key +- Consider weekly cache expiration +- Use `astral-sh/setup-uv` with smart cache management -**Why it happens:** -Config files are stringly-typed. Import path changes are invisible to them. The v1.0 extraction of viscy-transforms did not have this problem because transforms are passed as constructor arguments (MONAI `Compose`), not referenced by class path in configs. - -**How to avoid:** -1. Search all YAML/JSON files for `viscy.data` references: - ```bash - grep -r "viscy\.data\." applications/ examples/ configs/ --include="*.yaml" --include="*.json" - ``` -2. Create a migration guide document listing old -> new import paths for every public class. -3. Add a deprecation shim module (even though clean break is the policy): - ```python - # viscy/data/__init__.py (in the umbrella package, if it exists) - import warnings - warnings.warn( - "viscy.data is deprecated. Use viscy_data instead. " - "See migration guide: https://...", - DeprecationWarning, stacklevel=2 - ) - from viscy_data import * - ``` - This is optional and contradicts the "clean break" decision, but it prevents silent failures for existing users. -4. If clean break is firm (per PROJECT.md): ensure all known configs in the repository are updated in the same PR that extracts the package. - -**Warning signs:** -- Training scripts fail with `ModuleNotFoundError` or `ClassNotFoundError` weeks after extraction -- Users open issues about broken configs -- Saved experiment configs become non-reproducible - -**Phase to address:** -Code migration phase (update all in-repo configs).

During extraction, if the base classes are reorganized or their `__init__` signatures change, Python's Method Resolution Order (MRO) can break. Specifically: if `GPUTransformDataModule.__init__` calls `super().__init__()` but `SelectWell.__init__` expects different arguments, you get `TypeError: __init__() got an unexpected keyword argument`. +**What goes wrong:** Sphinx documentation with `_static/` and `_templates/` directories doesn't deploy correctly to GitHub Pages. -**Why it happens:** -Multiple inheritance with `super()` requires cooperative `__init__` chains. If any class in the MRO doesn't properly forward `**kwargs`, the chain breaks. This is fragile even without extraction, but extraction increases the risk because developers may refactor `__init__` signatures to "clean up" the extracted code. - -**How to avoid:** -1. Do NOT change `__init__` signatures during extraction. Copy first, refactor later. -2. Add explicit MRO tests: - ```python - def test_cached_ome_zarr_mro(): - mro = CachedOmeZarrDataModule.__mro__ - assert mro.index(GPUTransformDataModule) < mro.index(SelectWell) - ``` -3. Ensure all mixins accept `**kwargs` and forward them to `super().__init__(**kwargs)`. -4.

These memory-mapped files hold open file descriptors. In tests, if the fixture doesn't explicitly close/unmap these tensors, you get: (a) `PermissionError` on Windows when pytest tries to clean up `tmp_path`, (b) memory leaks in CI, (c) stale memory-mapped files accumulating in `/tmp` on long-running test sessions. +Annoyances that are easily fixable but worth knowing about. -**Why it happens:** -Memory-mapped files are OS resources, not Python objects managed by the garbage collector. `del tensor` doesn't immediately release the mmap. On Windows, you cannot delete a file that has an open memory map. - -**How to avoid:** -1.

Override `teardown()` in `MmappedDataModule` to explicitly close all `MemoryMappedTensor` handles. -3. On Windows CI, use `shutil.rmtree(tmp_path, ignore_errors=True)` as a fallback. -4.

The stack prioritizes: -viscy-data introduces three new concerns beyond viscy-transforms: +1. **Modern tooling** (uv, hatchling) over legacy (setuptools, pip) +2. **Workspace-native versioning** (hatch-cada + hatch-vcs) for independent package releases +3. **Zensical documentation** as the successor to Material for MkDocs +4. **Minimal configuration** with sensible defaults -1. **Heavy I/O dependencies** -- iohub (OME-Zarr), zarr, and tifffile form the core I/O layer that nearly every module requires. -2. **Optional heavyweight deps** -- tensorstore, tensordict, and pycocotools are only needed by specific modules (triplet, mmap_cache, livecell) and require optional dependency groups. -3. **Inter-package dependency** -- viscy-data depends on viscy-transforms (for `BatchedCenterSpatialCropd` in triplet.py), making this the first workspace package with a cross-package dependency. +--- -The core stack is: **iohub + monai + lightning + torch + numpy** as required dependencies, with **tensorstore, tensordict, pycocotools, pandas, tifffile, torchvision** available through optional extras `[triplet]`, `[livecell]`, `[mmap]`, `[all]`. +## Recommended Stack ---- +### Package Management & Build System -## Recommended Stack -- New Dependencies for viscy-data +| Technology | Version | Purpose | Why | Confidence | +|------------|---------|---------|-----|------------| +| uv | latest | Package manager, virtual env, workspace orchestration | Industry standard for 2025+; 10-100x faster than pip; native workspace support | HIGH | +| hatchling | >=1.28.0 | Build backend | Recommended by uv; extensible via plugins; better than setuptools for modern projects | HIGH | +| hatch-vcs | latest | VCS-based versioning | Derives version from git tags; eliminates manual version bumps | HIGH | +| hatch-cada | >=1.0.1 | Workspace dependency versioning | Rewrites workspace deps with version constraints at build time; enables independent releases | HIGH | -### Core Required Dependencies +**Rationale:** The combination of hatchling + hatch-vcs + hatch-cada is specifically designed for uv workspace monorepos. This replaces setuptools-scm which the current project uses. The uv build backend (`uv_build`) does NOT support plugins yet, so hatchling is required. -These are imported by the majority of modules and must be required (not optional). +### Dynamic Versioning Strategy -| Technology | Version | Purpose | Why This Version | Confidence | -|------------|---------|---------|------------------|------------| -| iohub | >=0.3a2 | OME-Zarr I/O (Plate, Position, ImageArray) | Matches original VisCy pinning; provides `open_ome_zarr`, `ngff` module used by 9 of 13 data modules | HIGH | -| monai | >=1.5.2 | Transforms (Compose, MapTransform), data utilities (ThreadDataLoader, set_track_meta, collate_meta_tensor) | 1.5.2 is current (Jan 2026 release); used by 10 of 13 modules; aligns with viscy-transforms pin | HIGH | -| lightning | >=2.3 | LightningDataModule base class | Every DataModule inherits from this; matches original VisCy pin | HIGH | -| torch | >=2.10 | Tensor operations, DataLoader, Dataset, DDP | Aligns with viscy-transforms pin (>=2.10); needed by all modules | HIGH | -| numpy | >=2.4.1 | Array operations | Aligns with viscy-transforms pin; iohub returns numpy arrays | HIGH | -| zarr | * | Zarr store access | Imported directly in hcs.py for decompression caching; version managed transitively via iohub | HIGH | -| imageio | * | Image reading (imread in hcs.py) | Used in hcs.py; lightweight; version managed transitively | MEDIUM | -| viscy-transforms | (workspace) | BatchedCenterSpatialCropd | triplet.py imports this; one-way dependency (data -> transforms), no circular risk | HIGH | +| Approach | When to Use | Configuration | +|----------|-------------|---------------| +| **hatch-vcs + hatch-cada** (RECOMMENDED) | Independent versioning per package | Package-specific git tags like `viscy-transforms@1.0.0` | +| uv-dynamic-versioning | Simpler single-package or lockstep versioning | Single version derived from any tag | -**Rationale for iohub >=0.3a2:** The original VisCy on main pins `iohub[tensorstore]>=0.3a2`. This is a pre-release version (alpha), which means the API may not be fully stable. However, VisCy has been using this version in production. The `[tensorstore]` extra on iohub itself is separate from our optional `[triplet]` extra -- iohub uses tensorstore for its own OME-Zarr v0.5 sharded access. We should pin `iohub>=0.3a2` as the base dependency and let users who need tensorstore-backed I/O install `viscy-data[triplet]` which includes both. +**Why hatch-vcs + hatch-cada over uv-dynamic-versioning:** +- hatch-cada properly handles workspace dependencies at build time +- hatch-vcs is mature and well-documented +- uv-dynamic-versioning's metadata hook is newer and less battle-tested for workspaces -**Rationale for monai >=1.5.2 (not >=1.4):** The original VisCy pinned >=1.4, but viscy-transforms already uses >=1.5.2. Since viscy-data depends on viscy-transforms, the effective floor is 1.5.2 anyway. Be explicit to avoid confusing lower bounds. +### Documentation -### Optional Dependencies (Extras) +| Technology | Version | Purpose | Why | Confidence | +|------------|---------|---------|-----|------------| +| zensical | >=0.0.19 | Static site generator | Successor to Material for MkDocs by same team; 4-5x faster incremental builds; Rust + Python | MEDIUM | +| mkdocstrings | latest | API documentation from docstrings | Standard for Python API docs; works with Zensical | HIGH | +| mkdocstrings-python | latest | Python handler for mkdocstrings | Required for Python docstring extraction | HIGH | -These are imported by specific modules only and should be lazy-loaded with clear error messages. +**Why Zensical over MkDocs:** +- MkDocs is unmaintained since August 2024 +- Material for MkDocs entered maintenance mode (November 2025) +- Zensical is the official successor, maintains compatibility with mkdocs.yml +- New projects should use zensical.toml (not mkdocs.yml) -| Extra Group | Dependencies | Used By | Why Optional | -|-------------|-------------|---------|--------------| -| `[triplet]` | tensorstore, pandas | triplet.py, cell_classification.py | tensorstore is a large C++ library (~100MB+); pandas adds weight; only needed for contrastive learning pipelines | -| `[livecell]` | pycocotools, tifffile, torchvision | livecell.py | pycocotools requires C compiler on some platforms; tifffile + torchvision only needed for LiveCell benchmark | -| `[mmap]` | tensordict | mmap_cache.py | Part of torchrl ecosystem; only needed for memory-mapped caching strategy | -| `[all]` | (union of above) | All modules | Convenience extra for users who want everything | +**Caution:** Zensical is still Alpha (0.0.x).

This is the second extraction milestone, building on the established patterns from viscy-transforms (Milestone 1). The extraction is architecturally straightforward — copy modules, update imports, declare dependencies — but has three significant complexities that distinguish it from viscy-transforms: (1) heavy I/O dependencies (iohub, zarr, tensorstore) with platform-specific constraints, (2) optional heavyweight dependencies requiring careful lazy loading, and (3) a one-way cross-package dependency on viscy-transforms for `BatchedCenterSpatialCropd`. +This research evaluated transforming VisCy from a single setuptools-based package into a modern uv workspace monorepo with independently versioned subpackages. The recommended approach uses **hatchling + hatch-vcs + hatch-cada** for build and versioning, replacing the current setuptools + setuptools-scm configuration. The first extraction targets `viscy-transforms` (GPU augmentation transforms), establishing patterns for future extractions. -The recommended approach follows the proven viscy-transforms pattern: flat module layout with underscore-prefixed private modules, top-level exports in `__init__.py`, optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`), and workspace dependency declaration. The critical difference is extracting shared utilities from `hcs.py` into `_utils.py` FIRST — this breaks the current dual-role pattern where hcs.py serves as both a concrete DataModule and a utility library, preventing fragile cross-module coupling. +The monorepo approach enables users to install only what they need (`pip install viscy-transforms` instead of the entire VisCy stack), reduces dependency bloat, and allows independent release cycles. Critical to success: agreeing on a single Python version floor (3.11+) across all workspace members, preventing import leakage via isolated testing, and using src layout to avoid development-time import confusion. The architecture requires careful dependency management since all packages share a single lockfile. -Key risks center on multiprocessing and cross-platform compatibility: the `Manager().dict()` shared cache pattern works on Linux (fork) but breaks on macOS/Windows (spawn), optional dependencies like pycocotools and tensorstore have platform-specific build requirements, and `ThreadDataLoader` with tensorstore creates test isolation challenges. These are mitigated by: (1) testing with `spawn` explicitly in CI, (2) using optional dependency groups with platform markers, (3) session-scoped test fixtures with explicit cleanup, and (4) a tiered CI matrix (base deps on 3x3, full extras on 1x1). +Key risks center on the shared lockfile constraint (conflicting dependencies between packages break the workspace) and the clean break in import paths (`from viscy_transforms import X` not `from viscy.transforms import X`). Applications and examples will have temporarily broken imports until updated. Mitigation requires phase-gated extraction with validation at each step, comprehensive CI testing per package, and clear migration documentation for downstream users. ## Key Findings ### Recommended Stack -The core stack is **iohub + monai + lightning + torch + numpy** as required dependencies, with **tensorstore, tensordict, pycocotools, pandas, tifffile, torchvision** available through optional extras. This represents an incremental addition to the workspace — the build system (hatchling + uv-dynamic-versioning), Python version support (3.11-3.14), and CI patterns are already established and do not need re-research. +The stack modernizes VisCy's tooling while maintaining compatibility with the scientific Python ecosystem. Core shift: **hatchling replaces setuptools** because it's extensible via plugins and integrates cleanly with uv workspaces. Dynamic versioning uses **hatch-vcs (git tag based) + hatch-cada (workspace dependency rewriting)** instead of setuptools-scm. This combination enables independent package versioning with tags like `viscy-transforms@1.0.0` while correctly handling inter-package dependencies at build time. **Core technologies:** -- **iohub >=0.3a2**: OME-Zarr I/O layer (Plate, Position, ImageArray) used by 9 of 13 modules; pre-release version but stable in VisCy production use -- **monai >=1.5.2**: Transforms (Compose, MapTransform), data utilities (ThreadDataLoader, set_track_meta, collate_meta_tensor) used by 10 of 13 modules; aligns with viscy-transforms pin -- **lightning >=2.3**: LightningDataModule base class for all data modules; matches original VisCy pin -- **torch >=2.10**: Tensor operations, DataLoader, Dataset; aligns with viscy-transforms for consistency -- **tensorstore (optional)**: High-performance array I/O for contrastive learning triplet cache; C++ library with platform wheel limitations; only needed for `[triplet]` extra -- **tensordict (optional)**: MemoryMappedTensor for mmap caching strategy; part of PyTorch RL ecosystem; only needed for `[mmap]` extra -- **pycocotools (optional)**: COCO annotation parsing for LiveCell benchmark dataset; requires C compiler on some platforms; only needed for `[livecell]` extra +- **uv** (package manager, workspace orchestration) — 10-100x faster than pip, native workspace support, industry standard for 2025+ +- **hatchling + hatch-vcs + hatch-cada** (build system + versioning) — Plugin-based extensibility; hatch-cada critical for workspace deps; hatch-vcs mature git versioning +- **Zensical** (documentation) — Official successor to Material for MkDocs (now in maintenance mode); 4-5x faster builds; Rust + Python +- **ruff** (linting + formatting) — Replaces black + isort + flake8; 200x faster; native Jupyter support; current project already uses it -**Version pinning philosophy:** Floor pins (`>=X.Y`) for core dependencies to avoid over-constraining user environments.

No version pins for optional dependencies — let the resolver pick compatible versions. +**Note:** Cannot use uv's native build backend (`build-backend = "uv"`) because it doesn't support plugins yet. Hatchling required for hatch-vcs/hatch-cada functionality. ### Expected Features -All 13 modules must be extracted and importable with clean paths (`from viscy_data import HCSDataModule`). The extraction must preserve all existing functionality while establishing a cleaner architecture through utility refactoring. Optional dependency groups enable users to install only what they need for their specific pipeline (translation, FCMAE pretraining, contrastive learning, or benchmarking). - **Must have (table stakes):** -- All 13 modules extracted with clean import paths (no `viscy.data.` references) -- Flat top-level exports for all DataModules and Datasets -- Type exports (Sample, NormMeta, TripletSample, etc.) for downstream type annotations -- Optional dependency groups (`[triplet]`, `[livecell]`, `[mmap]`, `[all]`) -- Workspace dependency on viscy-transforms (for `BatchedCenterSpatialCropd` import in triplet.py) -- Shared utilities extracted from hcs.py into `_utils.py` (breaks dual-role anti-pattern) -- Existing tests passing under new import paths -- py.typed marker for type checking support +- **Workspace member discovery** — `members = ["packages/*"]` glob pattern; users expect this to work +- **Shared lockfile** — Single `uv.lock` ensures reproducibility; standard uv workspace design +- **Editable inter-package dependencies** — `workspace = true` in sources; changes propagate immediately during development +- **Per-package testing** — `uv run --package viscy-transforms pytest` must work from any directory +- **Git-based versioning** — Dynamic version from VCS tags; avoids manual version bumps (scientific Python standard) +- **src layout** — `packages/*/src/*/` prevents import confusion; pytest/pip best practice +- **CI changed-package filtering** — Path-based filtering; don't test unchanged packages (monorepo efficiency requirement) **Should have (competitive):** -- Lazy imports for heavy optional deps with clear error messages when missing -- Package README with pipeline mapping table (adapted from existing `viscy/data/README.md`) -- GPU transform mixin as protocol for duck typing without forced inheritance -- Type-safe batch structures exported as first-class types +- **Reusable CI workflows** — DRY GitHub Actions with parameters; reduces maintenance overhead +- **API documentation generation** — Auto-generated from docstrings (mkdocstrings/Zensical); keeps docs synchronized +- **Package-specific documentation** — Per-package docs with cross-linking; docs stay close to code +- **Parallel test execution** — pytest-xdist for faster runs; easy win for large test suites +- **Independent versioning** — Each package has own version via package-specific tags; good for loosely coupled packages **Defer (v2+):** -- Promoting internal utilities like `_read_norm_meta` to public API (wait for user demand) -- Abstract cache interface unifying Manager.dict, tensorstore, and MemoryMappedTensor patterns (complexity without immediate benefit) -- Config-driven DataModule registry for Lightning CLI integration (wait for viscy meta-package) +- **Release automation** — python-semantic-release or manual workflow; manual releases acceptable initially +- **Coverage aggregation** — Combined coverage across packages; nice-to-have for later +- **Dependabot/Renovate** — Automated dependency updates; can add after initial stabilization +- **Dev containers** — Consistent environment via devcontainer.json; useful but not blocking ### Architecture Approach -The package uses a flat module layout following the viscy-transforms pattern. All modules use underscore-prefixed names (`_hcs.py`, `_utils.py`) to signal "import from package top-level, not from module." The internal dependency graph is a clean DAG with foundation modules (`_typing.py`, `_utils.py`) at the root, core modules (`hcs.py`, `gpu_aug.py`) in the middle, and specialized modules (triplet, livecell, mmap_cache) as leaves. +The architecture uses a **virtual workspace root** (not a distributable package) that coordinates multiple independent packages under `packages/*`. Each package uses src layout (`packages//src//`) with its own pyproject.toml, preventing import confusion and enabling true independence. The single lockfile at workspace root ensures consistent dependency resolution, while workspace dependencies declared via `[tool.uv.sources]` with `workspace = true` enable editable development. **Major components:** +1. **Workspace Root** — Defines membership via `[tool.uv.workspace]`, shared tooling config (ruff, mypy, pytest), not installable itself +2. **viscy-transforms (first extraction)** — Image transformations (kornia, monai based); standalone with no workspace dependencies +3. **viscy-data (future)** — Data loading, HCS datasets; may depend on viscy-transforms via workspace sources +4. **viscy-models (future)** — Neural network architectures; may depend on viscy-transforms +5. **applications/** — Publication code (not a package); broken imports acceptable during transition -1. **Foundation layer** (`_typing.py`, `_utils.py`) — Type definitions and shared utilities; no internal dependencies; imported by all other modules -2. **Core DataModules** (`hcs.py`, `gpu_aug.py`) — HCSDataModule for translation pipelines, GPUTransformDataModule (ABC) for FCMAE pretraining; depend only on foundation layer -3. **Specialized DataModules** (triplet, mmap_cache, livecell, cell_classification, cell_division_triplet, ctmc_v1, segmentation) — Pipeline-specific implementations extending core DataModules; may have optional dependencies -4. **Composition modules** (combined, concat) — Wrappers for multi-source training and dataset concatenation; depend on core modules -5. **Utilities** (select, distributed) — SelectWell mixin for well/FOV filtering, ShardedDistributedSampler for DDP; standalone with no internal dependencies - -**Critical architecture decision:** Extract shared utilities (`_ensure_channel_list`, `_read_norm_meta`, `_collate_samples`) from `hcs.py` into `_utils.py` BEFORE extracting any other modules. The current code has 5 modules importing from `hcs.py` for utility functions, not for `HCSDataModule`, creating unnecessary coupling. This refactoring is the prerequisite that enables clean module boundaries. +**Critical path:** Workspace scaffolding → First package extraction → Code migration → Test migration. Phases 5+ (dependency groups) and 6 (dynamic versioning) can run in parallel after Phase 2 completes. ### Critical Pitfalls -Based on analysis of the 13-module architecture, v1.0 extraction experience, and domain expertise with PyTorch/Lightning data loading patterns: - -1. **Lazy Import Guard Ordering Breaks at Runtime** — Optional dependencies (tensorstore, tensordict, pycocotools) must use lazy imports that defer errors until actual usage, not module import time. If guards are missing or placed incorrectly, errors surface deep in training loops (potentially in DataLoader worker subprocesses), making them hard to trace. Prevention: centralized lazy import pattern in `_imports.py`, call import helpers at method entry points, test with base-deps-only CI job to catch unguarded imports. +1. **Single requires-python constraint** — uv enforces workspace-wide Python version intersection. If one package needs 3.12+, entire workspace becomes 3.12+. Users on 3.11 cannot install any package even if individually compatible. **Mitigation:** Agree on Python 3.11 floor upfront; document in workspace root; all packages must use `>=3.11`. -2. **Manager().dict() Shared Cache Not Picklable Across spawn Contexts** — `CachedOmeZarrDataset` uses `multiprocessing.Manager().dict()` which works with `fork` (Linux) but fails with `spawn` (macOS/Windows default). Proxy objects must pickle, and depending on creation timing relative to DataLoader fork/spawn, you get either pickle errors or silently separate caches per worker. Prevention: create Manager in `setup()` (Lightning hook after multiprocessing context is configured), test with `mp_start_method="spawn"` explicitly in CI, consider replacing with file-based cache. +2. **Conflicting dependencies between members** — All packages share one lockfile. If viscy-transforms needs `numpy<2` and a future package needs `numpy>=2`, resolution fails and workspace cannot lock. **Mitigation:** Survey dependency constraints before adding packages; pin compatible ranges for PyTorch/NumPy early; consider path dependencies for genuinely incompatible packages. -3. **Base Class Extraction Creates Hidden Import Cycles** — `hcs.py` is both a concrete DataModule and the base class for TripletDataModule/CellDivisionTripletDataModule. Extracting utilities into `_utils.py` without careful dependency analysis creates circular imports. Prevention: map complete import graph BEFORE moving code, follow strict layering (_typing -> _utils -> hcs -> specialized), test import order explicitly with isolated `python -c "from viscy_data import X"` calls. +3. **Import leakage between workspace members** — Python doesn't enforce dependency boundaries. viscy-transforms can accidentally import from viscy-data even without declaring it, because both are in the same environment. Works in monorepo, fails for users. **Mitigation:** Test each package in isolation (`uv sync --package `); CI must test packages independently, not just whole workspace. -4. **Optional Extras Create a 2^N CI Matrix Explosion** — With 4 optional groups across 3 Python versions and 3 OS targets, testing all combinations creates 45+ jobs. Some combinations are invalid (pycocotools doesn't build on Windows). Prevention: tiered CI strategy (base deps 3x3, full extras 1x1, per-extra smoke tests), use pytest markers to skip when deps missing, exclude known-broken combinations in matrix. +4. **uv-dynamic-versioning requires hatchling** — Using `build-backend = "uv"` breaks dynamic versioning; uv-dynamic-versioning is a hatchling plugin. **Mitigation:** Always use `build-backend = "hatchling.build"`; verify version in built wheel before publishing. -5. **pycocotools Build Failure Blocks Windows CI** — pycocotools requires C compiler; Windows has no default C compiler. When wheels are missing, pip falls back to source build which fails. Prevention: exclude livecell extra from Windows in CI matrix, mark `[livecell]` as Linux/macOS only in docs (LiveCell is HPC dataset anyway), or use `pycocotools-windows` fork. +5. **Entry points lost during migration** — CLI commands (`viscy = "viscy.cli:main"`) stop working after setuptools → hatchling. Different config syntax; easy to forget. **Mitigation:** Audit all `[project.scripts]` sections; test CLI after migration: `uv run viscy --help`. ## Implications for Roadmap -Based on the dependency analysis and architecture patterns, the extraction follows a layered build order. The critical path is: scaffolding → foundation modules → core modules → specialized modules → composition modules → finalize. Tests can begin after core modules are migrated. +Based on research, suggested phase structure: -### Phase 1: Package Scaffolding & Foundation -**Rationale:** Establish package structure and dependency declarations before migrating any code. Extract shared utilities first to break the hcs.py dual-role anti-pattern. +### Phase 1: Workspace Foundation +**Rationale:** Establishes monorepo structure and prevents critical pitfalls (Python version floor, build system). Must come first because all packages depend on workspace configuration. **Delivers:** -- `packages/viscy-data/pyproject.toml` with all dependencies (required and optional groups) -- Empty `__init__.py` placeholder -- `py.typed` marker -- `_typing.py` with all data types (verbatim copy from `viscy/data/typing.py` + DictTransform alias) -- `_utils.py` with extracted helpers (`_ensure_channel_list`, `_read_norm_meta`, `_collate_samples`, `_search_int_in_str`) -- Root `pyproject.toml` updated with viscy-data workspace dependency - -**Addresses features:** -- Package structure (table stakes) -- Type exports (table stakes) -- Shared utilities extraction (table stakes, prevents coupling) -- Optional dependency groups (table stakes) +- Root pyproject.toml with `[tool.uv.workspace]` and `members = ["packages/*"]` +- Shared tooling config (ruff, mypy, pytest at workspace level) +- Python version floor decision (3.11+) documented +- Virtual workspace root (`package = false`) -**Avoids pitfalls:** -- P3 (import cycles) — extracting _utils.py first prevents coupling -- P1 (lazy imports) — pyproject.toml defines extras structure -- P5 (pycocotools Windows) — optional deps with platform markers +**Addresses:** +- Workspace scaffolding (table stakes from FEATURES.md) +- Shared lockfile requirement +- Pre-commit/prek hooks for quality gates + +**Avoids:** +- Pitfall #1 (Python version conflicts) by setting floor upfront +- Pitfall #4 (wrong build backend) by configuring hatchling immediately -### Phase 2: Core Data Modules -**Rationale:** Migrate the two base DataModule classes that other modules depend on. These have no optional dependencies and establish the inheritance patterns. +### Phase 2: viscy-transforms Package Extraction +**Rationale:** First extraction establishes patterns for future packages. viscy-transforms chosen because it's standalone (no workspace dependencies), well-isolated, and delivers immediate user value. **Delivers:** -- `hcs.py` (HCSDataModule, SlidingWindowDataset, MaskTestDataset) — remove extracted functions, update imports -- `gpu_aug.py` (GPUTransformDataModule ABC, CachedOmeZarrDataset, CachedOmeZarrDataModule) — update imports to viscy_data._utils -- `select.py` (SelectWell mixin) — verbatim copy, update imports -- `distributed.py` (ShardedDistributedSampler) — verbatim copy, no internal imports +- `packages/viscy-transforms/` with src layout +- Per-package pyproject.toml with hatchling + hatch-vcs + hatch-cada +- Git-based versioning configured (tag pattern: `viscy-transforms@X.Y.Z`) +- Clean import path: `from viscy_transforms import X` -**Uses stack:** iohub, monai, lightning, torch (all required deps) +**Uses:** +- hatchling build backend +- hatch-vcs for version from git tags +- hatch-cada for workspace dependency rewriting +- PEP 735 dependency groups for dev/test separation -**Implements architecture:** Foundation → Core layer in dependency DAG +**Implements:** +- src layout pattern from ARCHITECTURE.md +- Independent package testing workflow -**Avoids pitfalls:** -- P2 (Manager().dict() spawn) — CachedOmeZarrDataModule addressed in this phase -- P11 (MRO fragility) — copy-first, no refactoring during extraction +**Avoids:** +- Pitfall #3 (import leakage) via isolated testing from day 1 +- Pitfall #14 (src layout confusion) via clear documentation -### Phase 3: Specialized Data Modules -**Rationale:** Migrate pipeline-specific DataModules that extend core classes. These introduce optional dependencies and lazy loading patterns. +### Phase 3: Code and Test Migration +**Rationale:** Moves actual code after scaffolding is validated. Separating this from Phase 2 allows validation of structure before content. **Delivers:** -- `triplet.py` (TripletDataset, TripletDataModule) — add lazy imports for tensorstore/pandas -- `cell_classification.py` (ClassificationDataset, ClassificationDataModule) — lazy pandas import -- `cell_division_triplet.py` (CellDivisionTripletDataset, CellDivisionTripletDataModule) -- `mmap_cache.py` (MmappedDataset, MmappedDataModule) — lazy tensordict import -- `livecell.py` (LiveCellDataset, LiveCellTestDataset, LiveCellDataModule) — lazy pycocotools/tifffile imports -- `ctmc_v1.py` (CTMCv1DataModule) -- `segmentation.py` (SegmentationDataset, SegmentationDataModule) - -**Uses stack:** tensorstore, tensordict, pycocotools (all optional) +- Migrated code: `viscy/transforms/*.py` → `packages/viscy-transforms/src/viscy_transforms/` +- Updated imports within package +- Migrated tests: `tests/transforms/` → `packages/viscy-transforms/tests/` +- Updated test imports -**Implements architecture:** Specialized modules layer in DAG +**Addresses:** +- Test organization (table stakes) +- Clean import paths requirement -**Avoids pitfalls:** -- P1 (lazy imports) — centralized pattern for all optional deps -- P7 (ThreadDataLoader leaks) — addressed in triplet.py migration -- P12 (MemoryMappedTensor cleanup) — addressed in mmap_cache.py +**Avoids:** +- Pitfall #5 (entry points lost) by auditing and testing CLI +- Pitfall #2 (dependency conflicts) via careful dependency specification -### Phase 4: Composition Modules & Finalize -**Rationale:** Migrate the high-level composition wrappers that depend on core modules, then finalize the package with complete exports and README. +### Phase 4: CI/CD Updates +**Rationale:** CI must validate monorepo structure before merging. Comes after code migration so there's something to test. **Delivers:** -- `combined.py` (CombinedDataModule, CombineMode) — update imports -- `concat.py` (ConcatDataModule, BatchedConcatDataModule, CachedConcatDataModule, BatchedConcatDataset) — split from combined.py -- Complete `__init__.py` with all public exports (15 classes + 8 types) -- Package README adapted from `viscy/data/README.md` +- GitHub Actions workflows for monorepo testing +- Package-specific test jobs with path-based filtering +- Build verification (version correctness) +- Independent package testing validation -**Implements architecture:** Composition layer, public API surface +**Addresses:** +- CI changed-package filtering (table stakes) +- Path-based filtering requirement +- Build caching for efficiency -**Avoids pitfalls:** -- P8 (__init__.py eager imports) — only re-export modules with required deps +**Avoids:** +- Pitfall #11 (CI cache explosion) via `uv cache prune --ci` +- Pitfall #3 (import leakage) by testing packages in isolation -### Phase 5: Test Migration & CI -**Rationale:** Migrate existing tests after code modules are stable, establish test fixtures with proper cleanup, configure tiered CI matrix. +### Phase 5: Documentation Migration +**Rationale:** Documentation can be migrated after core functionality works. Zensical setup is independent of code migration. **Delivers:** -- `tests/conftest.py` with session-scoped OME-Zarr fixtures (migrate from main branch tests/conftest.py) -- `test_hcs.py` (update imports, verify HCSDataModule + SlidingWindowDataset) -- `test_triplet.py` (update imports, add ThreadDataLoader cleanup) -- `test_select.py` (update imports, verify SelectWell mixin) -- `test_typing.py` (new: smoke tests for type definitions) -- CI workflow with tiered matrix: base deps (3x3), full extras (1x1), per-extra smoke tests +- Zensical configuration replacing current docs +- Per-package documentation structure +- API documentation from docstrings (mkdocstrings) +- GitHub Pages deployment workflow -**Verifies:** All table-stakes features work, pitfall mitigations are effective +**Uses:** +- Zensical (successor to Material for MkDocs) +- mkdocstrings-python for API doc generation -**Avoids pitfalls:** -- P4 (CI matrix explosion) — tiered strategy keeps job count manageable -- P9 (expensive fixtures) — session-scoped, read-only fixtures -- P7 (ThreadDataLoader leaks) — explicit cleanup in fixtures -- P12 (mmap cleanup) — explicit teardown for MemoryMappedTensor +**Addresses:** +- API documentation generation (differentiator) +- Package-specific documentation -### Phase 6: Workspace Integration & Validation -**Rationale:** Verify the extracted package integrates correctly with the workspace and existing configs still reference correct import paths. +**Avoids:** +- Pitfall #12 (Jekyll interference) via `.nojekyll` file in deploy workflow -**Delivers:** -- Root `pyproject.toml` verified with viscy-data in dependencies and [tool.uv.sources] -- All YAML/JSON configs in applications/ checked for stale `viscy.data.` references -- Integration test: `uv sync --package viscy-data` + `uv run --package viscy-data pytest` -- Integration test: viscy meta-package can import from both viscy-transforms and viscy-data -- Documentation: migration guide with old → new import paths +### Phase 6: Validation and Documentation (Launch) +**Rationale:** Final validation before considering MVP complete. Documentation ensures future maintainers understand the patterns. -**Verifies:** Clean workspace integration, no config breakage +**Delivers:** +- Developer guide for monorepo workflow +- Migration guide for downstream users +- Example updates (fix broken imports in examples/) +- Version validation and test coverage verification -**Avoids pitfalls:** -- P10 (config class_path breakage) — grep + update all in-repo configs -- P6 (iohub API coupling) — integration test verifies iohub types +**Addresses:** +- Clean break import migration (VisCy-specific risk #3) +- Documentation of migration path ### Phase Ordering Rationale -- **Sequential dependency chain:** Foundation → Core → Specialized → Composition follows the import DAG. Each phase depends on the previous phase being complete. -- **Extract _utils.py FIRST:** This is the critical prerequisite. The current hcs.py dual-role creates coupling that blocks clean extraction of downstream modules. -- **Lazy imports in Specialized phase:** Optional dependencies are leaf nodes in the dependency graph. They're isolated in Phase 3 so Phase 2 can be tested without tensorstore/tensordict/pycocotools. -- **Tests after code:** Tests require all modules to exist. Session-scoped fixtures need the full package structure. Testing comes after Phases 1-4 are stable. -- **CI after tests:** The tiered CI matrix needs to know which tests can run with base deps vs. which need extras. CI design happens after test structure is known. +- **Foundation first (Phase 1):** Workspace configuration is prerequisite for all packages; Python version floor prevents rework +- **Pattern establishment (Phase 2-3):** First extraction creates blueprint for future packages; validating structure before content prevents large-scale rework +- **Validation early (Phase 4):** CI must validate monorepo before considering it functional; testing in isolation catches import leakage +- **Documentation deferred (Phase 5):** Zensical setup independent of code migration; can proceed in parallel with Phase 4 if resources allow +- **Launch preparation (Phase 6):** User-facing docs and examples updated after core functionality proven + +**Dependency ordering:** +- Phase 1 blocks all others (foundation) +- Phase 2 blocks Phase 3 (scaffolding before content) +- Phase 3 blocks Phase 4 (must have code to test) +- Phase 4 and Phase 5 can run in parallel after Phase 3 +- Phase 6 depends on all previous phases + +**Avoids pitfalls:** +- Phase-gated extraction prevents commitment to flawed structure +- Isolation testing at each phase catches import leakage early +- Build verification before merge prevents version issues in production ### Research Flags -**Phases with standard patterns (skip research-phase):** -- **Phase 1-4:** Code extraction follows the proven viscy-transforms pattern. All architectural decisions are documented in existing research. -- **Phase 5:** Test fixture patterns are well-documented in existing tests/conftest.py. CI workflow structure mirrors existing test.yml. -- **Phase 6:** Workspace integration is standard uv workspace mechanics. +**Phases needing deeper research during planning:** +- **Phase 2:** hatch-vcs tag pattern configuration (new as of v1.0.1, Jan 2026) — verify pattern syntax for monorepo +- **Phase 4:** GitHub Actions workspace testing patterns — sparse official guidance on monorepo path filtering +- **Phase 5:** Zensical migration from mkdocs.yml (Alpha software, v0.0.19) — may need fallback plan to mkdocs-material -**No phases need additional research.** All architectural decisions, dependency choices, and pitfall mitigations are informed by the comprehensive upfront research (STACK.md, FEATURES.md, ARCHITECTURE.md, PITFALLS.md) and the established viscy-transforms precedent. +**Phases with standard patterns (skip research-phase):** +- **Phase 1:** Workspace scaffolding — well-documented in uv official docs +- **Phase 3:** Code migration — standard Python refactoring patterns +- **Phase 6:** Documentation — standard technical writing ## Confidence Assessment | Area | Confidence | Notes | |------|------------|-------| -| Stack | HIGH | Core dependencies verified via lockfile and source code analysis. Optional dependencies verified via original pyproject.toml. Python version support follows workspace standard. | -| Features | HIGH | All 13 modules analyzed with direct source code review. Import paths, class hierarchies, and dependency graph documented in existing `viscy/data/README.md`. Feature requirements are table-stakes extraction, not new development. | -| Architecture | HIGH | Package layout follows proven viscy-transforms pattern. Internal dependency graph is well-documented (README.md). Shared utilities extraction is the only new architectural element, and it's a straightforward refactoring. | -| Pitfalls | MEDIUM-HIGH | Pitfalls derived from: (1) codebase analysis, (2) v1.0 extraction experience, (3) domain expertise with PyTorch multiprocessing, Lightning DataModules, tensorstore, and C-extension packages. WebSearch unavailable during research, so some cross-platform build claims (tensorstore arm64, pycocotools Windows wheels) could not be verified against current package indices. | +| Stack | HIGH | Verified with official uv, hatchling, hatch-vcs docs; multiple successful deployments (pydantic-ai, MCP SDK) | +| Features | HIGH | Based on uv official workspace docs and PEP 735; table stakes well-established in community | +| Architecture | HIGH | Patterns verified in official uv documentation; src layout is pytest/pip best practice | +| Pitfalls | MEDIUM-HIGH | Critical pitfalls verified in official docs; moderate/minor based on GitHub issues and community reports | **Overall confidence:** HIGH -The extraction is architecturally straightforward and follows established patterns. The three complexities (heavy I/O deps, optional deps, cross-package dependency) are well-understood and have documented mitigation strategies. The main uncertainties are platform-specific (tensorstore/pycocotools wheel availability), which are addressed by making those dependencies optional and testing in a tiered CI matrix. +Research is comprehensive with strong official documentation coverage. Lower confidence areas (Zensical, hatch-cada) have fallback options (mkdocs-material 9.7.0, uv-dynamic-versioning respectively) and don't block core functionality. ### Gaps to Address -**Platform-specific dependency availability:** -- **tensorstore Python 3.13 support:** Wheels may not exist yet. Mitigated by making `[triplet]` optional and testing extras only on Python 3.11-3.12 in CI. -- **pycocotools Windows build:** No pre-built wheels for some Python versions. Mitigated by excluding Windows from livecell tests in CI or documenting as Linux/macOS only. -- **tensordict Python 3.13 support:** Same mitigation as tensorstore (optional, narrower CI matrix). +**Gap: Zensical Alpha stability** +- **Impact:** Documentation generation may have bugs +- **Handling:** Keep mkdocs-material 9.7.0 as fallback; Zensical maintains compatibility with mkdocs.yml config +- **Validation:** Test Zensical during Phase 5 before committing; easy to roll back + +**Gap: IDE workspace support** +- **Impact:** VS Code/PyCharm may not understand workspace structure; import errors shown for valid code +- **Handling:** Configure `.vscode/settings.json` with Python paths; use `uv sync` to populate `.venv`; document in developer guide +- **Validation:** Test with both VS Code and PyCharm during Phase 1 -**iohub version stability:** -- iohub is pinned at pre-release (0.3a2) because stable release timeline is unknown. The API is stable in VisCy production use, but future releases may have breaking changes. Mitigated by floor pin (`>=0.3a2`), no upper bound, and integration test that verifies expected types/attributes. +**Gap: PyTorch + NumPy version matrix** +- **Impact:** NumPy 2.0 migration ongoing; PyTorch has tight NumPy requirements; potential dependency conflicts +- **Handling:** Pin NumPy range compatible with PyTorch 2.4+; test against both NumPy 1.x and 2.x in CI matrix +- **Validation:** Run `uv tree` during Phase 2 to inspect resolved versions; monitor NumPy 2.0 ecosystem compatibility -**Manager().dict() cross-platform:** -- Shared cache pattern works on Linux (fork) but needs testing on macOS/Windows (spawn). Mitigated by explicit spawn testing in CI. If failures persist, fallback is to document CachedOmeZarrDataModule as Linux-only or refactor to file-based cache (tensordict MemoryMappedTensor pattern already exists in mmap_cache.py). +**Gap: Docker build efficiency** +- **Impact:** Docker builds may copy entire workspace for every package; massive cache invalidation +- **Handling:** Defer to post-MVP; use `uv sync --frozen --package ` when available; structure Dockerfiles for minimal layer invalidation +- **Validation:** Measure Docker build times in CI during Phase 4; optimize if blocking -None of these gaps block the extraction. All have documented mitigation strategies that can be applied during Phase 2 (Manager().dict()), Phase 3 (optional deps), and Phase 5 (CI matrix). +**Gap: Release automation** +- **Impact:** Manual release process initially; potential for version tag errors +- **Handling:** Document manual release workflow clearly; consider python-semantic-release post-MVP +- **Validation:** Test manual release workflow during Phase 6 with test PyPI ## Sources ### Primary (HIGH confidence) -- `viscy/data/README.md` (modular-data branch) — Comprehensive module inventory, dependency graph, class hierarchy, GPU transform patterns -- All 13 source files in `viscy/data/` on main branch — Direct import statement analysis, function-level dependency tracing -- `packages/viscy-transforms/` — Established extraction pattern (pyproject.toml, __init__.py, _typing.py, CI structure) -- `main:pyproject.toml` — Original dependency pins: iohub>=0.3a2, monai>=1.4, lightning>=2.3 -- `uv.lock` — Resolved versions: monai 1.5.2, torch 2.10.0, numpy 2.4.2, tifffile 2026.1.28 -- `.planning/PROJECT.md` — Project constraints (no viscy-transforms dependency, clean break imports, optional extras) -- `.planning/ROADMAP.md` — Milestone 1 completion status, workspace patterns - -### Secondary (HIGH confidence) -- `main:tests/conftest.py` — Test fixture patterns for HCS OME-Zarr stores, tracks datasets -- `main:tests/data/test_hcs.py`, `test_select.py`, `test_triplet.py` — Existing test coverage and patterns -- MONAI `monai.data.__init__.py` — Flat API export pattern (100+ symbols from 20+ modules) -- viscy-transforms `__init__.py` — Sibling package pattern (44 exports, underscore-prefixed private modules) - -### Tertiary (MEDIUM confidence, needs validation) -- tensorstore Python 3.13 wheel availability — Claimed LIMITED based on historical lag, but not verified against current PyPI -- tensordict Python 3.13 wheel availability — Claimed LIMITED, same reason -- pycocotools Windows wheel coverage — Claimed REQUIRES C COMPILER for missing wheels, based on common CI failure pattern -- iohub latest stable release status — Pre-release 0.3a2 is used;

All other transform usage goes through MONAI's +`MapTransform` interface (transforms are passed in as constructor arguments). + +## Key Shared Helpers (from hcs.py) + +Several modules import utility functions from `hcs.py`: + +| Function | Used by | +|----------|---------| +| `_ensure_channel_list()` | `gpu_aug.py`, `mmap_cache.py` | +| `_read_norm_meta()` | `gpu_aug.py`, `mmap_cache.py`, `triplet.py`, `cell_classification.py` | +| `_collate_samples()` | `combined.py` | + +These should be extracted into a shared utilities module during subpackage conversion. + +## SelectWell Mixin Pattern + +`select.py` defines a `SelectWell` mixin class used via multiple inheritance: + +```python +# gpu_aug.py +class CachedOmeZarrDataModule(GPUTransformDataModule, SelectWell): ... + +# mmap_cache.py +class MmappedDataModule(GPUTransformDataModule, SelectWell): ... +``` + +This provides the `_filter_fit_fovs()` method for well/FOV selection. + +## Training Pipeline to DataModule Mapping + +Three training pipelines use different engine, DataModule, and Dataset combinations: + +| Aspect | FCMAE Pretrain | Translation Fine-tune | DynaCLR (Contrastive) | +|--------|---------------|----------------------|----------------------| +| Engine class | `FcmaeUNet` | `VSUNet` | `ContrastiveModule` | +| Source | `viscy.translation.engine` | `viscy.translation.engine` | `viscy.representation.engine` | +| DataModule | `CombinedDataModule` wrapping `CachedOmeZarrDataModule` | `HCSDataModule` | `TripletDataModule` | +| Dataset | `CachedOmeZarrDataset` | `SlidingWindowDataset` | `TripletDataset` | +| Batch structure | `list[list[dict]]` → collated `Sample` | `Sample` (`source`, `target`, `index`) | `TripletSample` (`anchor`, `positive`, `negative`) | +| GPU transforms | Engine-driven: `FcmaeUNet.train_transform_and_collate()` | None (CPU-only via MONAI `Compose`) | `TripletDataModule.on_after_batch_transfer()` | +| Caching | `Manager().dict()` shared cache per FOV/timepoint | Optional zarr decompression to `/tmp` | `tensorstore` cache pool | +| DDP support | `ShardedDistributedSampler` | Standard PyTorch shuffle | Standard PyTorch shuffle (`ThreadDataLoader`) | + +### FCMAE Two-Stage Workflow + +FCMAE uses the same model architecture (`FullyConvolutionalMAE`) across two stages +that swap both the engine class and DataModule: + +1. **Pretrain** (self-supervised MAE): `FcmaeUNet` engine with `CombinedDataModule` + wrapping one or more `CachedOmeZarrDataModule`s. The model runs with + `mask_ratio > 0` and `MaskedMSELoss`. GPU transforms are applied by the engine + in `train_transform_and_collate()` / `val_transform_and_collate()`. + +2. **Fine-tune** (supervised translation): `VSUNet` engine with `architecture="fcmae"` + and `HCSDataModule`. The encoder can be frozen via `freeze_encoder=True`. + All transforms are CPU-side MONAI `Compose` pipelines; no GPU transforms. + +The checkpoint from stage 1 is loaded into stage 2 via `VSUNet(ckpt_path=...)`. + +## GPU Transform Pattern Analysis + +GPU augmentation is implemented three different ways across the pipelines: + +### Pattern 1: Engine-Driven (FCMAE) + +`GPUTransformDataModule` defines abstract properties (`train_gpu_transforms`, +`val_gpu_transforms`, etc.) but does **not** override `on_after_batch_transfer()`. +Instead, the `FcmaeUNet` engine explicitly calls transforms in its training/validation +steps: + +```python +# FcmaeUNet.train_transform_and_collate() +for dataset_batch, dm in zip(batch, self.datamodules): + dataset_batch = dm.train_gpu_transforms(dataset_batch) +``` + +This gives the engine full control over transform ordering, collation, and shuffling. + +### Pattern 2: DataModule Hook (DynaCLR) + +`TripletDataModule` overrides `on_after_batch_transfer()` to apply transforms +per-key (`anchor`, `positive`, `negative`). Each key is transformed independently +via `_transform_channel_wise()`, which scatters channels into a dict, applies +MONAI transforms, and gathers back: + +```python +# TripletDataModule.on_after_batch_transfer() +for key in ["anchor", "positive", "negative"]: + batch[key] = _transform_channel_wise( + transform=self._find_transform(key), + channel_names=self.source_channel, + patch=batch[key], norm_meta=... + ) +``` + +### Pattern 3: CPU-Only (Translation) + +`HCSDataModule` applies all transforms (normalization + augmentation + crop) on +the CPU inside dataset `__getitem__()` via MONAI `Compose`. The only +device-transfer hook is `on_before_batch_transfer()`, which only slices the +target Z dimension for 2.5D models — no GPU augmentation. + +### Transform Flow Diagram + +```mermaid +sequenceDiagram + participant DS as Dataset.__getitem__() + participant DL as DataLoader + participant Hook as on_after_batch_transfer() + participant Engine as Engine.*_step() + + Note over DS,Engine: FCMAE Pretrain (Engine-Driven) + DS->>DL: cpu_transforms applied in CachedOmeZarrDataset + DL->>Engine: list[list[dict]] (raw batches per DataModule) + Engine->>Engine: dm.train_gpu_transforms() + collate + shuffle + + Note over DS,Engine: Translation Fine-tune (CPU-Only) + DS->>DL: normalize + augment + crop in SlidingWindowDataset + DL->>Hook: on_before_batch_transfer() slices target Z + Hook->>Engine: Sample (source, target) + + Note over DS,Engine: DynaCLR / Contrastive (DataModule Hook) + DS->>DL: raw patches from TripletDataset (no transforms) + DL->>Hook: on_after_batch_transfer() applies transforms per key + Hook->>Engine: TripletSample (anchor, positive, negative) +``` + +## Unification Assessment + +### What Can Be Shared + +- **CPU/GPU transform interface**: All three pipelines ultimately compose MONAI + `MapTransform`s. The `train_cpu_transforms` / `train_gpu_transforms` property + pattern from `GPUTransformDataModule` could be adopted as a standard interface. + +- **iohub I/O**: `CachedOmeZarrDataset`, `SlidingWindowDataset`, and + `TripletDataset` all read from OME-Zarr via `iohub.Position`. The + `_read_norm_meta()` helper is already shared. + +- **Caching strategy**: Both `CachedOmeZarrDataset` (Manager dict) and + `TripletDataset` (tensorstore cache pool) implement per-volume caching. A + common cache interface could standardize this. + +### What Cannot Be Unified + +- **Batch structure**: `Sample` (source/target), `TripletSample` + (anchor/positive/negative), and the FCMAE nested list format are fundamentally + different. Collation and transform application depend on this structure. + +- **Transform application logic**: FCMAE applies transforms to a flat list then + shuffles; DynaCLR transforms each triplet key independently with channel + scatter/gather; translation transforms during `__getitem__()`. These reflect + genuine differences in augmentation semantics. + +- **DataLoader type**: DynaCLR uses `monai.data.ThreadDataLoader` (thread-based + workers for GIL-friendly tensorstore I/O); FCMAE/translation use standard + `torch.utils.data.DataLoader`. + +### Recommendation: `GPUTransformMixin` + +Rather than forcing all pipelines into a single base class, introduce a +`GPUTransformMixin` that standardizes the **interface** while keeping per-DataModule +`on_after_batch_transfer()` implementations: + +```python +class GPUTransformMixin: + """Standard interface for CPU/GPU transform split.""" + + @property + @abstractmethod + def train_cpu_transforms(self) -> Compose: ... + + @property + @abstractmethod + def train_gpu_transforms(self) -> Compose: ... + + @property + @abstractmethod + def val_cpu_transforms(self) -> Compose: ... + + @property + @abstractmethod + def val_gpu_transforms(self) -> Compose: ... +``` + +This would allow: +- `CachedOmeZarrDataModule` to keep engine-driven GPU transforms (FCMAE pattern) +- `TripletDataModule` to keep its `on_after_batch_transfer()` with channel scatter/gather +- `HCSDataModule` to optionally adopt the interface with no-op GPU transforms + +The mixin decouples the **declaration** of transforms from the **application** +strategy, enabling engines to query any DataModule's transforms without knowing +which pattern it uses. + +## Shared Type Definitions (typing.py) + +`typing.py` defines types used across both `viscy.data` and `viscy.transforms`: + +| Type | Used in data | Used in transforms | +|------|-------------|-------------------| +| `DictTransform` | Yes (throughout) | Yes (extracted to `viscy_transforms._typing`) | +| `Sample` | Yes (hcs, livecell) | No | +| `ChannelMap` | Yes (hcs) | No | +| `NormMeta` | Yes (hcs, gpu_aug, triplet, mmap) | No | +| `HCSStackIndex` | Yes (hcs) | No | +| `TripletSample` | Yes (cell_division_triplet) | No | +| `SegmentationSample` | Yes (segmentation) | No | +| `AnnotationColumns` | Yes (cell_classification) | No | +| Label constants | Yes (cell_classification) | No | + +During the viscy-transforms extraction (Phase 3, already completed), only +`DictTransform` and `OneOrSeq` were copied into `viscy_transforms._typing`. +The rest remain data-specific. + +--- + +## Notes for viscy-data Subpackage Conversion + +### 1. Dependency on viscy-transforms + +`triplet.py` imports `BatchedCenterSpatialCropd` from `viscy.transforms`. +In a uv workspace, this becomes a package dependency: + +```toml +# packages/viscy-data/pyproject.toml +[project] +dependencies = [ + "viscy-transforms", # for BatchedCenterSpatialCropd +] +``` + +This is a **one-way dependency** (data -> transforms), so no circular dependency +issue. However, it couples the two packages. Consider whether +`BatchedCenterSpatialCropd` should move to viscy-data or if the dependency is +acceptable. + +### 2. Heavy Optional Dependencies + +Some modules have specialized dependencies that most users don't need: + +| Dependency | Module(s) | Size/Impact | +|-----------|-----------|-------------| +| `tensorstore` | `triplet.py` | Large C++ library | +| `tensordict` | `mmap_cache.py` | Part of torchrl ecosystem | +| `pycocotools` | `livecell.py` | Requires C compiler | +| `tifffile` | `livecell.py` | Light | +| `pandas` | `triplet.py`, `cell_classification.py` | Common but adds weight | + +**Recommendation:** Use optional dependency groups: + +```toml +[project.optional-dependencies] +triplet = ["tensorstore", "pandas"] +livecell = ["pycocotools", "tifffile"] +mmap = ["tensordict"] +all = ["tensorstore", "pandas", "pycocotools", "tifffile", "tensordict"] +``` + +Or use lazy imports with clear error messages. + +### 3. Extract Shared Utilities from hcs.py + +`hcs.py` serves as both a concrete data module AND a utility library. Before +extraction, refactor shared helpers into a `_utils.py`: + +``` +viscy_data/ + _utils.py # _ensure_channel_list, _read_norm_meta, _collate_samples + _typing.py # Sample, ChannelMap, NormMeta, etc. (from typing.py) + hcs.py # HCSDataModule, SlidingWindowDataset only + ... +``` + +### 4. typing.py Overlap with viscy-transforms + +`DictTransform` is defined in both `viscy/data/typing.py` and +`viscy_transforms/_typing.py`. For the subpackage: +- **Option A:** viscy-data re-exports from viscy-transforms (adds coupling) +- **Option B:** viscy-data defines its own copy (duplicates a one-line type alias) +- **Option C:** Create a shared `viscy-types` micro-package (over-engineering) + +**Recommendation:** Option B -- keep a local copy. `DictTransform` is a single +`Callable` type alias and duplication is preferable to adding a dependency just +for a type. + +### 5. HCSDataModule as Base Class + +`HCSDataModule` is the parent of `TripletDataModule` and +`CellDivisionTripletDataModule`. This inheritance means these three must stay in +the same package. The class is also tightly coupled to iohub's `Position` and +`Plate` types. + +### 6. GPUTransformDataModule Abstract Pattern + +`GPUTransformDataModule` is an abstract base that standardizes the CPU/GPU +transform split pattern. Four modules inherit from it (`CachedOmeZarrDataModule`, +`MmappedDataModule`, `LiveCellDataModule`, `CTMCv1DataModule`). This is a clean +abstraction that works well as a package-internal base class. + +### 7. combined.py Module Size + +`combined.py` contains 5 classes (`CombineMode`, `CombinedDataModule`, +`BatchedConcatDataset`, `ConcatDataModule`, `BatchedConcatDataModule`, +`CachedConcatDataModule`). Consider splitting into: +- `combined.py` -- `CombinedDataModule` (uses Lightning's `CombinedLoader`) +- `concat.py` -- `ConcatDataModule`, `BatchedConcatDataModule`, `CachedConcatDataModule` + +### 8. MONAI Dependency Depth + +Nearly every module depends on MONAI for transforms, data utilities, or +`set_track_meta`. MONAI is a large dependency (~hundreds of MB with all +transitive deps). This is unavoidable given the project's design, but worth +noting for install time. MONAI should be a required dependency, not optional. + +### 9. iohub as Core I/O Dependency + +Most data modules read from HCS OME-Zarr stores via `iohub`. This is a +required dependency. The `Position`, `Plate`, `Well`, and `ImageArray` types +from `iohub.ngff` are used extensively. Any change in iohub's API would require +coordinated updates. + +### 10. Distributed Training Support + +`distributed.py` provides `ShardedDistributedSampler` used by `gpu_aug.py`, +`mmap_cache.py`, and `combined.py`. This handles DDP sharding and should stay +as an internal utility within viscy-data. + +### 11.
