打开文件搜索matplotlibrc

打开这个文件，搜索backend关键字

# The default backend; one of GTK GTKAgg GTKCairo GTK3Agg GTK3Cairo

# MacOSX Qt4Agg Qt5Agg TkAgg WX WXAgg Agg Cairo GDK PS PDF SVG

# Template.

# You can also deploy your own backend outside of matplotlib by

# referring to the module name (which must be in the PYTHONPATH) as

# ‘module://my_backend’.
