I cloned the repo, installed with pip install -e ., ran ipython, and tried import prometeo. I get the error:

Type 'copyright', 'credits' or 'license' for more information
IPython 7.22.0 -- An enhanced Interactive Python. Type '?' for help.

Hi @vpatov! Sorry for the loose response. Indeed M1 is not supported at the moment. I should find some time to add the support soon...
