I'm not sure why the matplotlib examples page would contain weird
dependencies like that, rather than just having simpler examples.
As for 'pip', it is a replacement for 'easy_install', both of which
find and install python packages. pip is meant to improve on
easy_install, with new features and more stability.
And I think you figured out my exact problem:

Yep, unfortunately in ~/.matplotlib/matplotlibrc
this line was set to
backend : GTKAgg
So I fixed that. The other solution I found is to have at the top of
the plotting script the matplotlib.use() statement so that it uses
something else for a backend:
import matplotlib # Do this before importing pylab or pyplot
#matplotlib.use('Agg') # Anti-Grain Geometry (raster images)
matplotlib.use('PDF')
import matplotlib.pyplot as plt
Thanks!

Re: [Matplotlib-users] error: Gtk* backend requires pygtk to be installed
Hi Mike,
I tried to run it on windows.
Got error
D:\download\python>demo_axes_grid.py
Traceback (most recent call last):
File "D:\download\python\demo_axes_grid.py", line 2, in
from demo_image import get_demo_image
ImportError: No module named demo_image
Went looking on examples page and found there was a file name demo_image.py
http://matplotlib.sourceforge.net/examples/axes_grid/demo_image.html
However for whatever reason the source code was not downloadable (404
error), so I copied it off the html page.
After that the example ran fine under windows, ... I have never
installed anything called 'dsextras' and don't know what it is.
However it doesn't look like a gtk GUI to me., a quick check of the code
reveals no gtk type commands or imports?
I'd be questioning your configuration of matplotlib, there should be a
rc file somewhere, maybe you (or your distro) have set the backend to
gtk by default?
I don't have a system here without gtk installed, that I could test
example runs without it installed - sorry.
(what distro and what's a pip command?)
