[Matplotlib-users] saving PNG graphics on mac

[Gideon S. <gr...@co...>]

For some reason when trying to save in PNG format on OS X 10.5.2,  a  
window pops up with the error:

Matplotlib backend_wx error
cannot return std::string from Unicode object


This is with the simple scipy demo at http://www.scipy.org/Cookbook/OptimizationDemo1
