[IPython-dev] how to upgrade iPython on AWS ec2? ERROR: Line magic function `%matplotlib` not found.

[Thomas Kluyver]

Hi Andy,

You should be able to upgrade to IPython 1.2.1 on Python 2.6, and I believe
that has the %matplotlib magic.

Red hat is a very conservative Linux distro, which is why it still offers
Python 2.6. If that's not what you want, I'd use the Ubuntu LTS images,
which will definitely have Python 2.7.
