D:\workspace\fma_td\src\fma\library.zip\matplotlib\__init__.py:908: UserWarning: This call to matplotlib.use() has no effect
because the the backend has already been chosen;
matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
or matplotlib.backends is imported for the first time.
本文讨论了一个关于Matplotlib使用过程中的警告信息,指出如果在导入pylab、matplotlib.pyplot或matplotlib.backends之前未调用matplotlib.use(),则该调用将无效。文章强调了正确设置后端的重要性。
