Summary

• Point actions/setup-python@v5 at the existing requirements-macos-arm64.txt file when computing the pip cache key.
• Keep the CPU unit-test job and dependency installation unchanged.

Root cause

The workflow enabled cache: pip, but this repository does not have a default requirements.txt or pyproject.toml. setup-python therefore stopped before dependency installation or tests with:

No file ... matched to [**/requirements.txt or **/pyproject.toml]

Specifying the existing dependency file gives the cache action a stable, valid input without broadening the workflow.

Validation

• python -m py_compile inference.py tests/test_inference.py
• python -m unittest discover -s tests -v: 14/14 passed
• python -m pip check
• git diff --check
• Confirmed cache-dependency-path is a supported actions/setup-python@v5 input and that requirements-macos-arm64.txt exists.

This is a one-line workflow-only follow-up to #38.
