Ipython fails to display matplotlib fig directly

Community

See my following example:

In [8]: %matplotlib inline
   ...: 
   ...: import matplotlib.pyplot as plt
   ...: import matplotlib.ticker as ticker
   ...: 
   ...: # Create a simple plot
   ...: fig, ax = plt.subplots()
   ...: ax.plot([1, 2, 3, 4], [10, 20, 15, 25])
   ...: 
   ...: # Use AutoLocator to dynamically determine tick positions
   ...: ax.xaxis.set_major_locator(ticker.AutoLocator())
   ...: 
   ...: plt.show()
Shell is already running a gui event loop for tk. Call with no arguments to disable the current loop.
<Figure size 640x480 with 1 Axes>

How can I let ipython display the matplotlib fig directly?

See here for the related discussion.

Have you tried putting %matplotlib inline in a separate cell?

See below, but I’m not sure if I understand you correctly:

Installed gtk4 event loop hook.

This happens immediately on start, so you must have some configuration picking it. I don’t know where to find that, but I’m sure it’s somewhere in the IPython docs.

However, the inline backend doesn’t display in the IPython console. That’s for inline in the notebook. I’m not aware of a method of displaying figures in the console directly.

According to the description here, it’s controlled by c.InteractiveShellApp.gui, but I don’t set this option at all:

(datasci) werner@X10DAi:~/.ipython/profile_default$ ug c.InteractiveShellApp
ipython_config.py:c.InteractiveShellApp.matplotlib = 'inline'

See below for the configurations done before:
