I am trying to run the calibration module as follows:

cd ~/picar-x/example/calibration  
sudo python3 calibration.py

I get the following error:

Traceback (most recent call last):  
File “/home/dhewitt/picar-x/example/calibration/calibration.py”, line 2, in   
from picarx import Picarx  
ModuleNotFoundError: No module named ‘picarx’

I can see that the module “picarx” is located two directories up from the calibration directory.

Why can’t it see it?

Thanks,

Don
