(prop.get_family (), self.defaultFamily [fontext]))

Because there is no such font in the server.

1. ~ / .cache / matplotlib/fontList.json file stores font information that will be called when matplotlib runs. The above error indicates that there must be no Helvetica-related information or corresponding Helvetica.ttf file in this file.

two。 Download a Helvetica.ttf file online and put it in matplotlib's font directory (* * / matplotlib/mpl-data/fonts/ttf/) or the system's font directory (/ usr/share/fonts/)
