The default value is [8.0, 6.0] which can be changed of course. To know all the default values just inspect the value of ‘rcParams‘
import matplotlib.pyplot as plt
print(plt.rcParams) # to examine all values
print(plt.rcParams.get('figure.figsize')

on trying to plot any thing in ipython using matplotlib i got the following error
This application failed to start because it could not find or load the Qt platform plugin “xcb”.
Available platform plugins are: eglfs, kms, linuxfb, minimal, minimalegl, offscreen, xcb.
Reinstalling the application may fix this problem.
Aborted (core dumped)
for example the following command will produce the error
ipython -c 'import pylab; pylab.plot()'
matplotlib backend: Qt5Agg
