GitHub Workflows

Update Requirements

This workflow automatically updates the requirements.txt file based on Python imports found in Jupyter notebooks across the repository.

Triggers

The workflow runs on:

• Push to main: When notebooks (.ipynb files) are modified
• Pull requests: When notebooks are modified
• Schedule: Weekly on Mondays at 00:00 UTC
• Manual: Can be triggered manually via workflow dispatch

How it works

1. Scans all subdirectories for Jupyter notebooks (.ipynb files)
2. Extracts Python import statements from code cells
3. Maps import names to PyPI package names (e.g., sklearn → scikit-learn)
4. Generates an updated requirements.txt file with all unique packages
5. Creates a pull request if changes are detected

Script

The main logic is in .github/scripts/update_requirements.py, which:

• Recursively finds all notebooks
• Parses notebook JSON to extract imports
• Filters out standard library modules
• Handles common package name mappings
• Outputs a sorted list of dependencies
