Hi,
The issue could be because of relative paths. At the beginning of the notebook, try setting the paths like

import sys
sys.path.append(path)

where the path could be an absolute path to the python file or the folder containing __init__.py.
I hope this helps.

I think the directory is /app/yourpythonfile.py if its in the same directory as your notebook
