其实,网上说解决方法是加:
matplotlib.use('Agg')
但是代码里面:
# Set headless-friendly backend.
import matplotlib；matplotlib.use('Agg') # pylint: disable=multiple-statements
import matplotlib.pyplot as plt # pylint: disable=g-import-not-at-top
已经有了呀,很奇怪,最后面看到网上的解决方案:https://github.com/tensorflow/models/issues/4777

然后就搞定了,把

这个放在第一个,这样就ok了,其实可能是调用的先后顺序问题
