Problem

The setup steps defined in .github/copilot-setup-steps.yml were not being executed because the file was located in the wrong directory. GitHub Actions workflows must be placed in the .github/workflows/ directory to be recognized and executed by the GitHub Actions runner.

This caused issues when trying to verify the setup process, as running python -c 'import pytensor' would fail with:

ModuleNotFoundError: No module named 'numpy'

Solution

Moved the workflow file from .github/copilot-setup-steps.yml to .github/workflows/copilot-setup-steps.yml.

What This Enables

With the file in the correct location, the workflow will now:

1. Be properly recognized by GitHub Actions
2. Automatically trigger when:
   • Manually invoked via workflow_dispatch
   • The workflow file itself is modified (via push or pull request)
3. Execute the setup steps that:
   • Install Python 3.13 with Micromamba
   • Install all required dependencies (numpy, scipy, jax, etc.)
   • Install pytensor in development mode
   • Verify the installation by importing pytensor

This ensures that the Copilot agent environment is properly configured with all necessary dependencies before code execution.
