I have the same problem too. I did pip uninstall opencv-python-headless and it still does not work.

[Kitty1122]

Tried pip uninstall opencv-python-headless - didn't work
Also, pip uninstall opencv-python; pip install open-python - didn't work

Closed Spyder environment and opened it again - worked! :)

@LikhithChakravarthi Hi Addinational Solution :
Use Pycharm,
Install opencv-python and cv2 from the module installation location of the interpreter you will use from the interpreter options in Pycharm.
