I tried this, but I got this error-message. Can you give me some hints how to solve this?

import cv2 cv2.version '4.0.0'

OpenCV changed the interface of findContours(). It does not return an image anymore. Gladly my code doesn't use the returned image. Just remove imgEdge, in line 76 in https://github.com/pinae/Zozo-Measurer/blob/master/markers.py. Let me know if this solves your problem. I might update the code based on this to cv2 version 4.
