I was not successful to run the unit tests locally: ModuleNotFoundError: No module named 'classic_controllers'

Did I miss an optional install or is something missing from the requirements? Also, GitHub still reports the tests to not be successful for Python 3.8. Is that fixable?

I will look into it on Thursday.

Integration test still fails on my machine, all other tests seems successful.

Also, GitHub still reports Version 3.8 to have failing tests.

Formatting issues persist and make it hard to read coded matrices.
