how to uninstall opencv-python package installed by using pip in anaconda?

Question

I have tried to install OpenCV in anaconda. but when I use it, I figure out the instead of using OpenCV, the program using OpenCV-python and that why my program crashed. I type "conda uninstall opencv" but it just uninstalls OpenCV package not OpenCV-python. I also use " conda uninstall opencv-python" and "pip uninstall opencv-python" but it's not work.

To uninstall I used this line of code and it worked,

    sudo pip uninstall opencv-python

Resulted as given:

Solution 3

1. Go to directory where pip is installing your packages.
2. You should able to see the egg file that corresponds to the package you want to uninstall. Delete the egg file (or, to be on the safe side, move it to a different directory).
3. Do the same with the package files for the package you want to delete for (opencv-python)

Solution 4

According to official documentation, this issue must be solved quite easily:

pip uninstall opencv-python
