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
