How to install IPython3?

I found that installing ipython3 (JuPyTer) last version (JSON4 etc.) is harder that expected on Ubuntu 14.04.$ The problem is that default version of ipython3 using sudo apt-get install ipython3-notebook is the version 1.2.1 which is a bit old.

To install a good version without cloning the ipython rpositories one has to use pip3 for instance. Pip3 package are more up to date.

• sudo pip3 install ipython There will still be somme erros and you will have to install the last version of tornado and jsonschema
• sudo pip3 install tornado jsonschema --upgrade

Now you have a beautiful jupyter console!
