【出现问题的原因】问题在于，您使用的是一个交互式后端，它试图为您创建图形窗口，但由于您断开了启动模拟时可用的x服务器，所以失败了。

【解决方法】

使用非交互式后端(请参见后端？)比如：Agg(用于Png格式，PDF, SVG或PS。在生成图形的脚本中，只需在import matplotlib.pyplot as plt之前调用matplotlib.use(）即可，具体如下：

将导入更改为

import matplotlib
matplotlib.use('AGG')#或者PDF, SVG或PS
import matplotlib.pyplot as plt

永久解决办法：

mkdir -p $HOME/.config/matplotlib/ 
echo"backend: Agg" >> $HOME/.config/matplotlib/matplotlibrc
