当在最近Ubuntu更新后更新

后试图绘制matplotlib subplots时出现KeyError我无法再绘制matplotlib中的subplots。不完全确定是什么更新并导致此。我的版本是Ubuntu 17.04，matplotlib 2.0.0，python 2.7。有没有人有一个想法可能是什么原因？当在最近Ubuntu更新后更新

我只是尝试：

from matplotlib import pyplot as plt 
fig, axs = plt.subplots(3,3)

导致：

我想这很难找出是什么原因造成的，所以重新安装matplotlib可能是必需的。 – ImportanceOfBeingErnest

这奏效了！谢谢ImportanceOfBeingErnest :) 我所做的：

sudo -H pip uninstall matplotlib 
sudo -H pip install matplotlib

，现在，它再次工作。
