解決方法:
Problem Cause In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There is Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.
I resolve this issue following ways:
- I assume you have installed the pip matplotlib, there is a directory in you root called
~/.matplotlib
. - Create a file
~/.matplotlib/matplotlibrc
there and add the following code:backend: TkAgg
