Here is the fix simply add the below mentioned line along with your import statement.

import matplotlib matplotlib.use('Agg')

matplotlib.use('Agg') should be next to import matplotlib Hope this will help you..

I've experienced the same problem between Django runserver and matplotlib with Django 2.0 and python 3.X. Waiting for a patch for this problem, meanwhile, I solved it using gunicorn with nginx as frontend instead of the Django embedded server.
