Hello, and thank you for the time you will take to answer.
I got myself in trouble when trying to install opencv on my Fedora machine. I first followed this :
https://opencv-python-tutroals.readthedocs.io/en/latest/py_tutorials/py_setup/py_setup_in_fedora/py_setup_in_fedora.html
yum didn't work and cv2 couldn't be found, so I tried the complete install from the github repo, following the tutorial exactly step by step. When it fails again, I tried to add the path, but there were different problems: either cv2 couldn't be found or it can't find a module cv2.cv2
Now, I removed all folders manually from usr/ with cv2 in it, and I hope someone could help me fix the installation :D
