Use the get_backend()function to obtain a string denoting which backend is in use:
使用该get_backend()函数获取表示正在使用哪个后端的字符串：
>>> import matplotlib
>>> matplotlib.get_backend()
'TkAgg'
回答by Serenity
Another way to determine the current backend is to read rcParamsdictionary:
确定当前后端的另一种方法是读取rcParams字典：
>>> import matplotlib
>>> print (matplotlib.rcParams['backend'])
MacOSX
>>> matplotlib.use('agg')
>>> print (matplotlib.rcParams['backend'])
agg
