How many python installations do you have? Do you use virtual environments? How do you run your code?
RE: matplotlib isn't recognized after installation - Pavel_47 - Sep-18-2019
I guess I've one Python installation.
Anyway I can check - does exist any instriuction in Linux to check this ?
I use Jupyter as environment and run my code there.

if you are on Linux most distros come with python2 and python3 installed. python will run system python2, so I guess you installed matplotib in system python2. Now the question is what version runs in Jupyter
you can run
$ which python to see what version invoke python command.

The Jupyter version: 3.6.8
Executing $which python in terminal outputs this: Python 2.7.15+
Resolved.
The instruction sudo apt-get install python3-matplotlib fixed the problem.
Thanks.

Remember to use
pip3 in the future not pip(as it install to Python 2).Look also at pyenv Simple Python Version Management can make stuff simpler.
