Broken in jupyter console

[lukelbd]

I get the following traceback in a jupyter console session with the itermplot==0.5 version recommended in the readme. Using pip install --upgrade itermplot to version 0.331 also does not help.

In [1]: fig, ax = plt.subplots()
   ...: fig.show()

experiencing the same issue

edit:
adding matplotlib inline before importing matplotlib fixed the issue for me:

%matplotlib inline
import matplotlib.pyplot as plt
