`sphinxext/ipython_directive.py` no longer in matplotlib

まず make html を実行し、sampledoc/sphinxext/ipython_directive.py と sampledoc/ipython_directive.rst を調べてから、警告に記載されている他のファイル custom_look.rst、cheatsheet.rst、extensions.rst を確認します。ディレクティブが現在の matplotlib で動作し、報告されるソース位置が有用で、インデントと参照の問題が修正され、ドキュメントのビルドがこれらのエラーや警告なしで完了すれば完了です。

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:
