See original GitHub issue

First of all, thank you for this great library!

face_recognition version: latest
Python version: 3.5.6

Description

Trying to run the webcam example on my mac using command python webcam_recongnition.py.

keep getting this error on command line

qt.qpa.plugin: Could not find the Qt platform plugin "cocoa" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

I tried to install mac version of PT platform but the command gave me an error about ‘more than 1 binary’.

any advise would be much appreciated!

resolved. If you are on a mac, make sure you install opencv-python-headless instead of opencv-python to avoid these errors.

you all should not install ‘opencv-contrib-python-headless’ package because this is for server. Opening the window with cv2.imshow does not seem to be a problem, but the closing button does not work.

So, you should install previous version. pip3 install --user opencv-contrib-python==4.1.2.30 The close button does work well.
