[Matplotlib-users] I get a warning when running code with ipython, but not with python

[Alejandro W. <ale...@gm...>]

Hi:

I just installed matplolib from source code, and Ipython using pip, in
Ubuntu 11.10.

When I run this code

########### foo.py ############
import matplotlib.pyplot as plt
plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.show()
##############################

in ipython, I get the following warning:

In [1]: %run foo.py
/usr/lib/python2.7/dist-packages/gtk-2.0/gtk/__init__.py:54: Warning:
ignoring sys.argv: it must be a list of strings
  _gtk.init_check()

Other than the warning the plot looks OK.

Also, if I type each sentence in ipython, I don't get the warning. I
don't get a warning if I use the standard python interpreter either
(as in $ python foo.py).

Any clue about this? Should I report this in the Ipython mailing list?

I am running Ipython 0.11 and matplotlib 1.2.x.
