Fix Windows MAX_PATH failure in CI model download step#2
Conversation
The snapshot_download call was writing temp .incomplete files to a
path 261 chars long — 1 char over the Windows 260-char MAX_PATH limit:
{workspace}/test_models/stable-diffusion-turbo-amdnpu-onnx/
.cache/huggingface/download/text_encoder/<hash>.incomplete
The existing "Enable Windows long path support" step silently swallows
admin-privilege errors when setting the HKLM registry key, so it
cannot be relied upon.
Fix: use C:\m as $modelsDir, reducing the longest temp path from 261
to 194 chars — safely within MAX_PATH regardless of OS long-path
support.

snapshot_downloadwrites temp files to{local_dir}/.cache/huggingface/download/{subdir}/{hash}.incomplete. With models stored under the workspace path, this produces a 261-char path — 1 char over Windows' 260-charMAX_PATHlimit, causing aFileNotFoundError.The existing "Enable Windows long path support" step silently swallows admin-privilege errors when writing to
HKLM, so it is not a reliable fix.Change
$modelsDir = "C:\m"instead of"${{ github.workspace }}/test_models", reducing the longest temp-file path from 261 → 194 chars — safely underMAX_PATHregardless of OS long-path registry state.
