unable to open camera [BUG]

[Daryatnt]

I'm facing this error while I'm trying to compile the code :

I am having the same problem, any progress about the solution? :)

Uninstalling opencv-python and installing it with the following command fixed my problem:
pip3 install git+https://github.com/opencv/opencv-python

Try an OpenCV version specified in the README.md release notes. Keep in mind 4.4.1 JetsonHacksNano wrote was a typo. But 3.3.1 and 4.1.1 worked for me.

Try running: https://gist.github.com/luke-han/55047815e0dc2c446f5e184d9d0201cc for OpenCV 3.3.1
