Answer 1

You can change the backend used by matplotlib by including:

import matplotlib
matplotlib.use('TkAgg')

before your line 1 import matplotlib.pyplot as pl, as it must be set first. See this answer for more information.

(There are other backend options, but changing backend to TkAgg worked for me when I had a similar problem)
