pip uninstall opencv-python-headless -y

pip install opencv-python --upgrade

worked for me btw

@edehino thanks for the tip! I'll try this in the docker image to see if it can resolve the cv2 4.6 errors I've been seeing

@edehino doesn't affect Docker image as if I try to uninstall I get:

WARNING: Skipping opencv-python-headless as it is not installed.
