[Matplotlib-users] TkAgg won't plot - how to debug?

Mon Nov 6 16:09:00 EST 2017

Tkinter was most likely installed as part of rpm install.
Backends - not really. I do know that with mpld3and agg  the scripts hang.
Ihave reinstalled matplot using rpm ( rpm comes only in 1.5 version) and
with pip3.
Today i tried on the office machine (fedora 25). Rpm brings only matplot1.5.

maybe 2 installed locally using pip3 messes with 1.5 leftover or libraries.
Not sure how to validate this idea though..
Probably unrelated:
In pycharm pyplot is not been recognized as part of matplotlib when i
"import matplotlib.pyplot. yet the script doesnt crash on import
statement...

How did you install Tkinter? Have you tested any other backends? Does this
happen for just the head-less "Agg" backend set as default?
