I registered a new video about How to install python and Opencv on Windows as in the previous one there were a few mistakes. I made the installation process much easier in this new video.
I want to thank the user @foxfire374 for commenting in the previous video and for giving me tips for improvement.

Thanks for the video. Your website has an error I believe in the code to install OpenCV and numpy. Your video shows "python -m pip" and the webpage shows "python pip -m". The webpage way gave me errors. This is steps 5 & 6.

[Liberciaa]

I did everything like in the video and finished without problem but I'm still getting warning when I'm trying to import cv2 in pycharm it says, Unused import statement 'import cv2'. I'm using virtualenv environment. Also when I try file<settings<python interpreter<install packages<cv2 it says,
ERROR: Could not find a version that satisfies the requirement cv2 (from versions: none)
ERROR: No matching distribution found for cv2
I dont get it I can download some packages and can't download others... I tried many solutions and stuck... Please help

[Turbopasta]

for anybody who's getting "ImportError: DLL load failed while importing cv2: The specified module could not be found." when trying to run import cv2, try typing this into cmd: pip install opencv-contrib-python

import cv2 and import numpy both seem to work fine with no errors now
