Matplotlib GUI showing even though I never called plt.show()

Question

I am using the following functions in order...

 - plt.figure()
 - plt.plot()
 - plt.ylim 
 - plt.xticks() 
 - figure = plt.gcf() 
 - figure.set_size_inches()
 - plt.savefig()

I just want to save the figure as png, which I've been doing successfully. But the GUI keeps showing up and I am going to generate a bunch of graphs in one script, I don't want the GUI popping up every time one is created and slow my run time.

Does anyone know why it is showing up still?

Jonah, did my answer below solve your problem? If so, please kindly mark it as such. Thanks. — avi, Mar 14 '21 at 11:24

If you are using a Jupyter Notebook, there are a number of potential solutions posted here.

To summarize, try this to disable inline output from Matplotlib:

import matplotlib as plt
plt.ioff()

Or put this at the start of a cell to prevent it from creating output:

%%capture

I'm using PyCharm as an IDE. I've tried plt.ioff() and it hasn't worked in the past. – Jonah Dafilou Mar 15 '21 at 14:58

You have to use plt.ioff() after the first plot, otherwise it will still show the images. – Cesar Flores Apr 17 '23 at 15:47
