The good thing is I figured how to launch the .py file, sadly now i have this problem

pyroot ClassificationKeras.py
Traceback (most recent call last):
  File "ClassificationKeras.py", line 17, in <module>
    from keras.models import Sequential
  File "/snap/root-framework/121/usr/local/lib/ROOT/_facade.py", line 121, in _importhook
    return _orig_ihook(name, *args, **kwds)
ModuleNotFoundError: No module named 'keras'

Thanks for any help in advance
