Question

当我运行栅格化示例found here并将bbox_inches='tight'参数添加到任何savefig()函数时，我收到以下错误。还有其他人有这个问题吗？我找不到错误报告。我使用matplotlib 1.4.0和python 2.7.6

这是已修复的已知错误（https://github.com/matplotlib/matplotlib/pull/3434）（https://github.com/matplotlib/matplotlib/pull/3453）。

如果您可以编辑安装，则需要删除三个字符。您还可以下载相关代码更改的差异（https://github.com/jowr/matplotlib/commit/2191358c4d0dd2a705c418376a8a0e9e22c4ca9d.diff），可以应用补丁。
