Translate content of jupyter notebook using gettext tools.

$ git clone https://github.com/devrt/nbtranslate.git
$ cd nbtranslate
$ sudo pip install -r requirements.txt
$ sudo ./setup.py install

or

$ pip install git+https://github.com/devrt/nbtranslate.git

Extract text to translate from the jupyter notebook:

$ nbtranslate --pot en.pot notebook_en.ipynb

Translate en.pot using your favorite gettext translation tool (I recommend poedit or google translator toolkit).

Save the translated result to entoja.po and then apply the translation:

$ nbtranslate --po entoja.po notebook_en.ipynb > notebook_ja.ipynb
