How to Install OpenCV on a Raspberry Pi

what is the meaning of PEP 517

Stupid Python again? The title is misleading. I wish someone would show how to install the actual OpenCV library, the C++ one.

Hi Sam, Great video, very easy to follow and the installation was “successful” at the conclusion of the second hour. Upon ‘import cv2’, however, I’m getting a message saying the package requires ‘numpy’ and goes on to say it could be a set up issue. I tried to install ‘numpy’ per the error message and I get the message “numpy requirements already satisfied”. What am I doing wrong? Thanks, Ed

I've run the pip install opencv-contrib-python and after 2 hours or so, the line at the end of the ... in building wheel for opencv-contrib-python (pep 517) stopped turning

Please provide me the installation of webcam not picam.

I want to code in C++. Does it work with this installation?

Dose it not work on 32bit os?

I'm trying the pip install opencv-contrib-python and it keeps saying "collecting opencv-contrib-python killed" then jt just stops

This is the best I have seen.

downloading opencv litreally took 1min not 2hours, does that makes any problem?

If you are stuck on "building wheel". Try to use the 64-bit OS instead of the 32-bit Version (the recommended one)
I tried to get it working for around one week before i tried this. After i changed the OS Version to 64-bit it worked on the first try.

you said it will take 2 hrs mine took 10 minutes

you save my life again and so many time

Hi, I installed opencv according to your guide.
