[yt-users] issue with wx python and matplotlib

[Matthew Turk]

Hi Eric,

I haven't seen this before, but it is a puzzler -- wx is famous for
having multiple versions concurrently instaleld, however, so I guess
it's not completely surprising.  It might be as simple as looking at
"import wx;print wx,wx.__version__" to see what it's importing.  I'd
recommend that you switch off the wx backend in Matplotlib.  There are
a couple ways to do this:

1)
import matplotlib;matplotlib.use("Agg")

2)
edit ~/.matplotlibrc and set backend to agg.

3)
launch python with -dAgg
