Hello,
I encountered another problem when compiling the pytorch image the way I did before. The following link is the problem I mentioned earlier.

I found this warning in the above log. Do you need to manually delete it?

Hi,

Not sure why it tries to remove CMake when uninstalling the OpenCV.
It should be better to keep it since CMake is commonly used.

It looks like just a warning so it’s recommended to ignore it if no other issues occur.

Thanks.
