Hello,

I found this issue while installing.

Getting requirements to build wheel ... error

I ran the script and found the issue below that causes 'No keyword found'. I'm not sure it relates to the above issue or not. Any suggestion to resolve this case?

Thank you in advance

Could be because opencv-python no longer supports Python 2.7. You could try installing an older version:
pip install opencv-python==4.2.0.32 and try again.

Thank you for reply. I change python version to 3.5 and install open

Thank you for your suggestion. I change python version to 3.5 with recommended opencv-python. I still got this issue when I run a script

Do you still have this issue when trying to install latest version @kattinum?

On Windows, also the installation of opencv-contrib-python is needed.
