@User This kis something we have ran into, its a side effect of running pip-compile from windows. We actually ended up with 3 requirements files. If you were to split like this, it is more complicated but will cut down on what you install in docker. I suspect that you do not need pywin32 in docker, you only need it with jupyter. * base/prod - everyone installs this everywhere (kedro, pandas...) * ci - These are neede when ci is running (pytest, docs, ...) * dev - includes handy dev tools like (jupyter, ipython...)
