Uninstall openCV on python 2 and python 3

Question

OS: Ubuntu 18.04-LTS bionic

i downloaded openCV using the command
sudo apt-get install python-opencv from the link

https://docs.opencv.org/3.4/d2/de6/tutorial_py_setup_in_ubuntu.html

This installs openCV 4.2 onto both my python 2.7 & python 3.6.9. I wanted to remove openCV and i used this command in terminal sudo apt-get --purge autoremove python-opencv When i call the version in terminal

    python
 import cv2
 cv2.__version__

only python2.7 openCV is removed but not python3.6.9.Please help me

If you have multiple python versions you can run cmd commands like this:

py -3.X -m pip uninstall opencv-python

So use this to try uninstalling opencv for every python version you have installed.
