Python doesn't import a module from another folder inside of parent folder

Question

I am having so much trouble with imports and I never know how to solve them. The folders of the project are arranged as follows

project:
   distributed_computing:
       agent_server.py
   kinematics:
       inverse_kinematics.py

I am trying to import inverse_kinematics into agent_server.py.

The code used for that is :

import os
import sys
sys.path.append(os.path.join(os.path.abspath(os.path.dirname(__file__)), '..', 'kinematics'))

from kinematics import inverse_kinematics

I get the error ModuleNotFoundError: No module named 'kinematics'.

Following this tutorial I also tried to modify PYTHONPATH by adding the whole path C:\Users\TheCh\.......\project but it didn't change anything.

The script should not worry about modifying sys.path. It should assume that it will be executed in an environment where the top-level package kinematics is located in a directory in sys.path. That's what

PYTHONPATH=/path/to/project python /path/to/agent_server.py

does, no matter what the current working directory is.
