Pycharm - Importing Matplotlib

Question

I've installed Pycharm and using Anaconda 3 as my interpreter. I cannot import Matplotlib (or Seaborn). When I run 'import matplotlib.pyplot as plt' I get the following:--

import matplotlib.pyplot as plt

Backend Qt5Agg is interactive backend. Turning interactive mode on.

Try running pip install PyQt5 in the command line (not Python, windows cmd or unix terminal). If this doesn't work - try conda install PyQt5. Though this doesn't make sense as matplotlib uses tkinter.
