py:445: UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure. % get_backend())

问题

I was trying to run the Mask-RCNN repository provided by the matterport in Github. https://github.com/matterport/Mask_RCNN. when I run the demo in the anaconda, it showed "C:\Anaconda\lib\site-packages\matplotlib\figure.py:445: UserWarning: Matplotlib is currently using agg, which is a non-GUI backend, so cannot show the figure. % get_backend()) ". Is there someone came cross the similar problem?

回答1:

If you are trying to plot on a remote server, ssh X11 forwarding can then be used to display matplotlib plots.

Try to use this,

import matplotlib
matplotlib.use('tkagg')

Make sure you have XMing or XQuartz (if you're on mac), and use -Y

$ shh -Y username@servidorIP
