InsightFace Stable ABI Wheels

Fork of deepinsight/insightface that publishes:

  • a single cp311-abi3 wheel per platform (works on Python 3.11+),
  • compiled cleanly against NumPy 2.x (forward-compatible with NumPy 1.x consumers),
  • with the PR #2870 modernization (PEP 621 metadata, regenerated Cython output) and the PR #2849 albumentations-warning fix already applied.

The default branch for this fork is abi3_stable.

Index

https://appmana.github.io/forks-insightface-stable-abi/

(insightface uses onnxruntime and has no CUDA dependency, so the index has no cu128/cu130 layering — one wheel set fits all GPUs.)

Install With pip

pip install insightface --index-url https://appmana.github.io/forks-insightface-stable-abi/

Install With uv

uv pip install --system insightface --index-url https://appmana.github.io/forks-insightface-stable-abi/

pyproject.toml example for uv:

[[tool.uv.index]]
name = "insightface"
url = "https://appmana.github.io/forks-insightface-stable-abi/"
explicit = true

[tool.uv.sources]
insightface = { index = "insightface" }

Build From Source

uv pip install --system "setuptools>=80" "numpy>=2.0" "cython>=3.1" wheel build
python -m build --wheel python-package

The wheel is written to python-package/dist/.

Dev Notes

  • The only C extension is insightface.thirdparty.face3d.mesh.cython.mesh_core_cython, rewritten to use typed memoryviews so the generated C compiles under Py_LIMITED_API=0x030B0000.
  • Py_buffer only entered the Python stable ABI in 3.11 (PEP 688), which is why the floor is cp311-abi3 rather than cp39-abi3 like the sister sageattention/nunchaku forks.
  • Wheel ABI compliance is verified in CI via abi3audit.
  • Built with cibuildwheel for Linux x86_64/aarch64, macOS x86_64/arm64, and Windows AMD64.
