Upload any lib/*.py files to Google Colab

colab_bootstrap.py

Minimal bootstrap script for running Jupyter notebooks in both local and Google Colab environments.

Purpose

Solves the chicken-and-egg problem of needing setup code before you can load your setup code. This script:

  • Detects whether you're running locally or in Colab
  • Sets up Python paths appropriately
