`sphinxext/ipython_directive.py` no longer in matplotlib

首先运行 make html，检查 sampledoc/sphinxext/ipython_directive.py 和 sampledoc/ipython_directive.rst，然后查看警告中提到的其他文件：custom_look.rst、cheatsheet.rst 和 extensions.rst。当该指令能够与当前的 matplotlib 一起工作、报告的源位置有用、缩进和引用问题已修复，并且文档构建在没有这些错误或警告的情况下完成时，即视为完成。

First of all: thanks for making this great tutorial!

It doesn't work with matplotlib HEAD though, because matplotlib/sphinxext/ipython_directive.py no longer exists.
This worked for me:
cp ipython/docs/sphinxext/ipython_directive.py sampledoc/sphinxext

After that a missing import numpy as np in combination with @doctest on line 120 in sampledoc/ipython_directive.rst makes sphinx abort.
For me simply adding the missing import numpy as np doesn't work, the doctest still fails.
Is it possible to make the following error message point to the .rst file name and line number that contains np.random.rand(10,2) (instead of suggesting a bug in sphinx)?

There's a few more small issues:
