Getting the same errors on a Home Assistant OS setup with OS 8.2

[OkhammahkO]

Same issue.

[McGiverGim]

The problem remains in Home Assistant 2022.8.0...

[markfrancisonly]

fortunately I was able to replace opencv with pillow for my application, maybe someone else here will have the same option

[McGiverGim]

The problem remains in september version...

I found the solution there is to change on the manifest.json "numpy", "opencv-python-headless==4.7.0.72" this will install correctly openCV

And it appears to be getting attention here:

I can confirm this fixes my issue too! A bit more info for others, what I did was bascially copy the dev version of the opencv componet into my custom components folder and then make the opencv-python-headless version change. I also needed to add "version": "1.0"

[sca075]

I simply used "requirements": ["numpy", "opencv-python-headless==4.7.0.72"] Open CV use numpy as dependences normally it should not be needed to install it, anyhow.. I´ve also see Frank is working on it in the log of this component.
