Import from a parent's parent package (Python)

Question

The following is my folder structure:

/experiments
    /experiment_1
    /experiment_2
    /experiment_3
        /src
           /sample.py
helper.py

All experiments share some code, which I have exported into helper.py. Now I'm trying to import a function from helper.py into sample.py:

from ...helper import my_function

and I get the following error:

ImportError: attempted relative import with no known parent package

Please note that I have tried many solutions offered here, but none worked.

Not all folders are packages. A package is a special folder accessible from the Python path. — Serge Ballesta, Feb 09 '22 at 09:53
