You can do "pip list" to see a list of packages installed using pip. There's also no harm in reinstalling.

pip install matplotlib should print a lot of stuff

Output:
c:\projects\bergen>pip install matplotlib

If already installed, the output is a lot shorter

Yes, thanks, maybe in those details there's an indication of what's wrong, wouldn't mind your opinion

Output:
C:\Users\richb>pip install matplotlib
