Opencv Can't Be Found But Can Be Imported

I've installed opencv from source using a virtualenv, however I faced some errors and needed to reinstall it. I tried removing all the files with sudo find / -name 'opencv' -exec r

Solution 1:

Run this command from your installed environment.

pip uninstall opencv-python

and if you are using Python3 than

pip3 uninstall opencv-python

Solution 2:

I found out that I hadn't uninstalled in the build folder, problem solved!
