ipython problem after upgrade

After I Syu'd, I found that ipython has shifted to python3. However, matplotlib is still dependent on python2. When I start ipython with the --pylab flag, I get a 'no module name matplotlib' error.

Install ipython2.

Also, if you have ipython-docs installed you'll have to manually remove it and add ipython2-docs.

Re: ipython problem after upgrade

The upgrade breaks emacs-ipython-mode as well.  I've changed my
previous setup in .emacs

(setq py-python-command-args '("--pylab"))
(require 'ipython)

to a new setup,

(setq ipython-command "/usr/bin/ipython2")
(setq py-python-command-args '("--pylab"))
(require 'ipython)

and I have installed ipython2.  Starting up the IPython shell in emacs
generates the following error

Traceback (most recent call last):
  File "<string>", line 1, in <module>
NameError: name 'olors' is not defined
>>>

I'm a bit stumped at this point.

find out why it is trying to use 'olors' instead of 'colors'
grep can be handy for this.

Sidenote, ipython does some silly things, so beware that some scripts might not run in it but run fine standalone, or the other way around.

Re: ipython problem after upgrade

The latest version of ipython.el fixes the "olors" problem. See comment (and references therein) by mauro2 for more
