Instructions

1. Make sure you have installed python3.10.13 or do sudo apt install Python3.10.13.
2. Clone the repo.
3. (Recommended) Create and activate a virtualenv under the env/ directory. Git is already configured to ignore it.
4. Install the very minimal requirements using pip3 install -r requirements.txt
5. Run Jupyter in whatever way works for you. The simplest would be to run pip3 install jupyter && jupyter notebook.
6. Activate your virtual environment with source venv/bin/activate,
7. Run Python script within your virtual environment.
