`sphinxext/ipython_directive.py` no longer in matplotlib

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)?

make: *** [html] Error 1

There's a few more small issues:

• Line 101 in sampledoc/ipython_directive.rst needs to be indented
  Users/deil/github/sampledoc/custom_look.rst:6: (WARNING/2) Duplicate explicit target name: "sphinx".
  /Users/deil/github/sampledoc/cheatsheet.rst:7: WARNING: undefined label: cheatsheet -literal (if the link has no caption the label must precede a section header)
  /Users/deil/github/sampledoc/extensions.rst:53: WARNING: undefined label: extensions-literal (if the link has no caption the label must precede a section header)

Bắt đầu bằng cách chạy make html và kiểm tra sampledoc/sphinxext/ipython_directive.py cùng sampledoc/ipython_directive.rst, sau đó xem xét các tệp khác được nêu trong các cảnh báo: custom_look.rst, cheatsheet.rst và extensions.rst. Công việc được xem là hoàn tất khi directive hoạt động với matplotlib hiện tại, vị trí mã nguồn được báo cáo là hữu ích, các vấn đề về thụt lề và tham chiếu được sửa, và quá trình build tài liệu hoàn tất mà không có các lỗi hoặc cảnh báo này.
