linux服务器导入python matplotlib.pyplot报错

在linux服务器端执行python脚本，有时候需要画图，但是linux没有GUI界面，因此需要在导入matplotlib.pyplot库之前先执行

import matplotlib as mpl

mpl.use('Agg')

再执行

import matplotlib.pyplot as plt

需要保存图片到指定的目录

plt.savefig("/home/yourname/test.jpg")

如果直接执行import matplotlib.pyplot as plt会报错：

>>> import matplotlib.pyplot as plt
