The command % python3 -c "import cv2" gives ModuleNotFoundError: No module named 'cv2' because the cv2 package is not installed at /usr/lib64, but rather % qlist opencv | grep cv2/__init__ /usr/lib/python3.6/site-packages/cv2/__init__.py Moving the directory cv2 under /usr/lib64 make cv2 work again. Reproducible: Always
After re-emerging it works with python-3.7 because in python-3.7 sys.path uses /usr/lib: % python3.7 -c "import sys; print(sys.path)" ['', '/usr/lib/python37.zip', '/usr/lib/python3.7', '/usr/lib/python3.7/lib-dynload', '/usr/lib/python3.7/site-packages'] but python-3.6 does not: % python3.6 -c "import sys; print(sys.path)" ['', '/usr/lib64/python36.zip', '/usr/lib64/python3.6', '/usr/lib64/python3.6/lib-dynload', '/home/xxx/.local/lib64/python3.6/site-packages', '/usr/lib64/python3.6/site-packages'] By the way, cv2 is the only python package on my system installed to /usr/lib/python3.6/site-packages/.
