Yes "pip install ..." and "sudo apt install ..." did run without errors.

pip list made this output:

But

sudo apt install libgstreamer-plugins-base0.10-dev

gives this error:

Error:
Reading package lists... Done

E: Unable to locate package libgstreamer-plugins-base0.10-dev
E: Couldn't find any package by glob 'libgstreamer-plugins-base0.10-dev'
E: Couldn't find any package by regex 'libgstreamer-plugins-base0.10-dev'

And please don't forget my problem is with Python3, not Python2.

OK I tried something on my own:

pip3 list

and the output was:

Output:
