      • Colabs

        Colab is a web-based Notebook service that requires no setup to use and provides free access to computing resources, including GPUs and TPUs. Colab is especially well suited to machine learning, data science, and education (e.g. to lean python, JAX, Tensorflow, Pytorch…).

        Marimo - Reactive notebook for Python

        Marimo is an open source Python-based notebook environment that makes working with data more interactive and intuitive. It supports both Python scripts and notebooks, allowing for seamless version control through Git.

        Marimo’s standout feature is its reactive UI, where changes in one part of the notebook automatically update other dependent parts, making it ideal for real-time data exploration.

        It is easy to use with plenty of features for advanced users. For example, it can be used to create interactive tools like embedding visualizers.

  • update notebooks
    • create a virtual env 
      python3 -m venv my-env-jupyter
source my-env-jupyter/bin/activate
deactivate          # how to leave/exit/deactivate
source deactivate   # if this doesn't work, try
