Simply delete the line

In order to make some interaction possible, an interactive backend needs to be used. So it will not work out of the box in IPython when %matplotlib inline mode is set. Options you have:

• Using %matplotlib notebook in IPython Qt console or jupyter notebook.
• Using a GUI backend when running code as a script, by adding plt.show(). In Spyder that can be ensured by running the script in a new dedicated window as sketched here.
