I tried running your code via docker-compose. After some building time, none of the notebooks in examples-folder worked. The notebook with the title "10 minutes to pypolars" was missing the pip command which I had to add to your Dockerfile (actually python-pip3). After rebuilding the whole thing and restarting the notebook, I had to change "!pip" to "!pip3" (was to lazy to add an alias) in the first code-cell which installed all dependencies after running. All the other cells resulted in errors. I suggest to focus on stability and reproducibility first and then on performance.
