Hi,
I have experienced some problems when using the tfplot using the new version of matplotlib.
More details about the error are:

Traceback (most recent call last):
  File "tmp.py", line 169, in <module>
    main()
  File "tmp.py", line 160, in main
    summary = session.run(summary_op)

AttributeError: 'FigureCanvasBase' object has no attribute 'tostring_argb'

I have solved it by reinstalling an older version of matplotlib == 3.0.2

Best,
Osama

@wookayin
Fix matplotlib 3.1+ issue (#18)
7a55191 
Starting from matplotlib 3.1, Figure instances have .canvas attribute
by default, which however lacks tostring_argb(). To make it work
regardless of matplotlib version (<3.1, >=3.1), use agg-backend canvas.
