[Short note] In matplotlib, nothing is displayed even if I show it → Check the backend setting

The backend may not be GUI.

python

import matplotlib as mpl
mpl.use('tkagg')

Is evaluated before import matplotlib.pyplot` (written in the line above).

** ʻImport Error: No module named backend_tkagg.pyis displayed: ** It looks like the backend is not installed. Installation is required with apt-get or yum. For SUSE sudo zypper in python-matplotlib-tk` (python3-matplotlib-tk for Python3)

** Now I can do it, but it's a hassle to do this every time ** Describe in the matplotlibrc file.

~/.config/matplotlib/matplotlibrc

backend : tkagg

For Linux, .config/matplotlib/matplotlibrc On other platforms, .matplotlib/matplotlibrc If you don't know

python

import matplotlib as mpl
print(mpl.get_configdir() + '/matplotlibrc')
