ipython

Ipython's not behaving as expected; this is hardy. I think i installed it
early on, with

sudo apt-get install ipython

on running it, arange doesn't work. I can't install pylab etc. Start again.

$ sudo aptitude install bzr
$ bzr branch lp:ipython

Read the installation instructions and found:

$ sudo easy_install ipython[kernel,security,test]

this bloody failed, too. Try:
$ sudo easy_install ipython

seems ok.


*UPDATE*

This same command, seems to safely update ipython, too! The change from 0.8.1 to 0.9.1 was seamless. Numpy, scipy and my modules import fine. ipcluster didn't work, though: twisted
was required.

$ sudo easy_install twisted

amazing. It worked. Now foolscap is missing.

$ sudo easy_install foolscap

Unbelievable. It worked, and

$ ipcluster -n 4

works, too.

Update, May 2013:

sudo apt-get install ipython-notebook python-matplotlib \ 

python-scipy python-pandas python-sympy python-nose

now works!
