Add EP download progress bar to all samples by bmehta001 · Pull Request #621 · microsoft/Foundry-Local

bmehta001 · 2026-04-09T15:35:37Z

All samples now show per-EP download progress with name and percentage, matching the pattern already in native-chat-completions samples.

Changes (38 files across 4 languages):

C# (9 samples): Replaced bare \DownloadAndRegisterEpsAsync()\ and \RunWithSpinner\ calls with progress callback
JS/TS (12 samples): Replaced bare \downloadAndRegisterEps()\ with progress callback
Python (9 samples): Replaced bare \download_and_register_eps()\ with progress callback
Rust (8 samples): Replaced \download_and_register_eps(None)\ with \download_and_register_eps_with_progress\

Each callback tracks the current EP name and displays a carriage-return progress line showing EP name (left-aligned 30 chars) and download percentage.

Add download_and_register_eps (or language equivalent) to all sample applications that were missing it. This ensures execution providers are downloaded and registered before model loading, which is required for variants like NvTensorRTRTX to appear in the catalog. Changes across 33 files in 4 languages: - C# (4 tutorials): await mgr.DownloadAndRegisterEpsAsync() - Python (9 samples): manager.download_and_register_eps() - JavaScript/TypeScript (12 samples): await manager.downloadAndRegisterEps() - Rust (8 samples): manager.download_and_register_eps(None).await?

Pull request overview

This PR updates the multi-language samples to display per–execution provider (EP) download progress (EP name + percent) while running download*AndRegisterEps*, aligning sample UX across C#, JS/TS, Python, and Rust.

Changes:

Added per-EP progress callbacks to EP download/registration calls across all samples.
Standardized console progress output formatting (carriage-return line with aligned EP name + percentage).
Updated one JS Electron sample to serialize SDK initialization via an initPromise.

Calling .ok() on the flush() result silently discards any I/O error in a way that can look accidental. If the intent is to ignore flush failures in a sample, using an explicit discard (e.g., assigning to _) makes that intent clearer; alternatively, log the error once to stderr if you want troubleshooting hints without failing the sample.
