If you want to run the code locally, first get a Python distribution. I use Miniconda. Alternatively, you could run it on Google Colab.
Install required packages. Using Python built-in tools you could do it like this:
pip install jinja2 notebook ipykernel matplotlib numpy wordcloud
Using conda, you could create an environment like this:
conda create -n snufa python=3 jinja2 notebook ipykernel matplotlib numpy wordcloud
conda activate snufa
Then run the notebook you’re interested in, either using Jupyter command line tool:
jupyter notebook
Or you could use vscode
and set it to use this kernel.
