Matplotlib works with python 2.7 but No module named in python 3.6

[zillurbmb51]

Hello, I am using centos7. I have both python 2.7 and 3.6 installed. Matplotlib is fine with python 2.7 but in python 3.6 it shows No module named 'matplotlib' I have tried uninstall and reinstall with pip3 but nothing works. I have tried all the possible ways... Any Help?

I seems like you have installed matplotlib for your system python (the one in /root/.local/lib/python3.6/site-packages), but you are trying to use it in an Anaconda environment called (base). If you want to install it in that anaconda environment use

python -mpip install matplotlib

That is, python3.6 is not an executable of your environment.

[WeatherGod]

Don't do "sudo pip install" or "sudo pip3 install" for all sorts of reasons (mainly because it can mess up the system python that gets managed by your package manager). Furthermore, what is happening for you is that you are doing the install as root (due to sudo), and matplotlib at some point in time got installed into root's ~/.local rather than the system python's site-packages. The root's ~/.local is not accessible to anybody else on the system, hence why a regular user can not find the matplotlib that was installed as root. Please consider using user-space level package managers such as conda or for python-only management, something like venv.
