Python - Generate Requirements

Description​

Generate a requirements.txt file for your Python project or environment directly from SAS Studio. This custom step allows you to either:

  • Freeze all packages in a given Python environment, or
  • Generate requirements based on the imports used in a folder of Python scripts.

This enables reproducible, portable analytics workflows and helps ensure your Python dependencies are clearly documented for deployment or sharing.
