matplotlib is currently using a non-GUI backend ERROR

[AgustinPardo]

Hello, I'm trying to run the first code lines of the tutorial:

import matplotlib matplotlib.use('Agg') import venn labels = venn.get_labels([ range(10), range(5, 15) ], fill=['number', 'logic']) print labels fig, ax = venn.venn2(labels, names=['list 1', 'list 2']) fig.show()

And I recibe this error:

/usr/local/lib/python2.7/dist-packages/matplotlib/figure.py:459: UserWarning: matplotlib is currently using a non-GUI backend, so cannot show the figure "matplotlib is currently using a non-GUI backend, "

Do you know what is the problem and how to solve it?

The error message seems to imply that you are working in a headless console. So fig.show() is meaningless. Are you looking for:

fig.savefig('demo.png', bbox_inches='tight')

[AgustinPardo]

That worked out!

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

and using import matplotlib

Agg backend runs without a display

matplotlib.use('Agg')
import matplotlib.pyplot as plt

Use fig.savefig('demo.pdf')

Try this: matplotlib.use( 'tkagg' )

[ash-aldujaili]

%matplotlib inline

install python-tk or python3-tk for python3

sudo apt install python3-tk

I was using venv with several versions of Python installed in VM. Installing python3-tk did not work. But installing the PyQt5 via pip solved this problem for me:

pip install PyQt5

[neurosignal]

Just give the command: %matplotlib qt5

if qt5 is not available, install it first as: pip install PyQt5
