I am trying to import matplotlib.pyplot using python3.6, but an error appear.

ModuleNotFoundError: No module named '_tkinter

Importing tkinter directly in a python script gives the same error.

I have also tried installing tkinter, but still fail to be imported in python3.6

python3-tk is already the newest version (3.5.1-1).

Installing python3.6-tk gives

Matplotlib and tkinter work fine when using python2.7 and 3.5. I guess the problem is to install tkinker for python3.6, but I failed to install it.

Thanks

  • Maybe the [accepted answer here](https://stackoverflow.com/questions/50327906/importerror-no-module-named-tkinter-please-install-the-python3-tk-package) will help you? – Billal Begueradj May 17 '18 at 04:48
  • @BillalBEGUERADJ The answer allows me to import matplotlib without error, but still cannot generate the plots visually using plt.show(). So I might still want to install tkinter. – Watsup MyMan May 17 '18 at 05:33
