OpenCV can't be found but can be imported

问题

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 rm {} \; and checked if the package was removed with pkg-config --modversion opencv, and it said it could not be found, but when I open the terminal with python3 and enter import cv2 then print(cv2.__version__), the terminal returns 4.0.0. How can I completely remove opencv? I'm on Ubuntu 18.04 LTS.

回答1:

Run this command from your installed environment.

pip uninstall opencv-python

and if you are using Python3 than

pip3 uninstall opencv-python

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