I am a beginner at computers. I use Anaconda python 3.6 in windows 10. I have already installed OpenCV using this command:
In my case, using Python 3.8 on Windows 10 and Pycharm (or VS Code as well), I have this same issue.
Finally I noticed that the Antivirus (Nod32) deletes the cv2.cp38-win32.pyd
file that should be in the cv2 folder. I simply paused the protection, installed opencv with pip install opencv-python
command and it worked just fine.
I hope it helps someone.
