Delete OpenCV installation in Ubuntu. [closed]

I installed OpenCV4 using the following command in Ubuntu 20.04:

sudo apt-get install python-opencv

It imports fine, but I need to undo this installation so I can build it from Source like this document states.

I ran the following command:

dpkg --get-selections | grep -v deinstall | grep opencv

Instead of uninstalling all files one by one, I did this:

sudo apt-get --purge remove libopencv*

Would that be enough or should I do something else?

Thanks for any advice!

Thank you! I performed some tests as well and it was imported OK. It is strange, making the build for the install is better if you have other packages that require a cmake build, this way they can find the packages properly. Using the apt-get you can't even find the folder that hosts the OpenCV installation, only a sort of wrapper on the directory of Python.

Yes. That is sufficiently. It should be ok.
