ModuleNotFoundError: No module named 'cv2'

I got this error:

Traceback (most recent call last):
  File "/lib/security/howdy/compare.py", line 19, in <module>
    import cv2
ModuleNotFoundError: No module named 'cv2'

Are you using that "recommended" package on openSUSE? It's completely broken. For some reason the package "depends" upon OpenCV3, where the runtime actually uses OpenCV2.

I'm not familiar with OpenCV (or Python) in general, but I've read that v3 can be substantially faster than v2; therefore, I'm wondering if any efforts are being made to migrate the project over to it.

Feel free to re-open it if you can provide more information.

For what it's worth - I'm no linux or python expert, but after trying lots of stuff online I ended up with:

Run sudo python Run each of the import lines from cli/test.py - see which fails. eg:

import configparser
import os
import sys
import time
import dlib
import cv2

Had to install dlib using pip install dlib - worked fine Then tried getting cv2 (opencv-python) a bunch of ways, but the only way that worked for me was

sudo apt install -y python3-opencv

Test now running and trying to get the rest set up.
