IPython3 on SL (RHEL)

I am running IPython (and especially a notebook server) on Scientific Linux 6.3 (thus RHEL). I tried to use python3 to run setup and use ipython and also the ipython3 command. However this fails all the time. Before I go into detail with error messages and such - I read somewhere that IPython3 is currently not supported for RHEL derivates (I think the post was relating to Fedora), is this true?

Cheers

Phil

I understand that this is a fairly old question. However, given that Fedora 20 (the current version) comes with IPython 0.13 which lacks some functionality of IPython 2, I decided to write down how I installed it, in hopes that someone might find it useful. My focus was on the newest version of IPython Notebook.

Edit: I was just made aware of this IPython backport repo.

All yum and pip* commands here are to be run as the root. Those disliking such approach can prepend sudo do all yum and pip* commands and run the rest of them without sudo.

Remove RPMs of IPython (to avoid collisions):

yum remove python-ipython\* python3-ipython\*

Install pip:

yum install python-pip python3-pip

Install additional Python dependencies (it did work for me without these, but I didn't test much, so something might break down without these):

yum install python-jinja2 python-markupsafe python3-jinja2 python3-markupsafe python-devel python3-devel

Install IPython for both Python 2 and Python 3:

pip install ipython[all]
pip-python3 install ipython[all]

I've read somewhere that on Ubuntu, pip-python3 is called pip3.

To run IPython Notebook for Python 2 (do this as an ordinary user, not the root):

ipython notebook

To run IPython Notebook for Python 3 (do this as an ordinary user, not the root):

ipython3 notebook

To test your installation, call iptest or iptest3 (again, as an ordinary user, not the root). These tests may fail, so you might need additional packages for them to pass. For me, PyZMQ failed. This was fixed by installing two more packages:

yum install python-zmq-tests python3-zmq-tests

Many thanks to IPython-dev mailing list members Zoltán Vörös, for pointing me in the right direction, and Roberto Colistete Jr., for additional Python dependencies.
