How to run examples

[Sciss]

Hello. Noobie question, as someone not really familiar with pip - if I follow the README and run pip install --editable ., this happens, but how do I run example code?

I'm kind of lost here as to the next step. I installed juypiter via pip install jupyter --user, then run jupyter-notebook and in the browser try to open an example. But something is not right:

$ jupyter-notebook

Seems a conflict between python (debian) and python (pip). After doing sudo apt remove python-configparser and reinstalling juypter via pip, this goes away. However, now I seem to have to install more packages by hand.

Dear Hanns,

I recommend that you use a dedicated Python environment for your research. We typically use Anaconda since this comes with, e.g., Numpy built-in.
