What version of matplotlib are you using? I have a vague recollection
that this was fixed at one point.
In any case, you should be able to get around this by casting your
filename to a string as such:
self.figure.savefig(str(image_file))
Hope that works for you,
Mike

Hello,
I'm trying to use savefig in my wx app and I'm using wxAgg backend. I'm
getting this error:
FILE .maplotlib\backends\backend_bases.py, line 397 in print_png
Self.get_renderer()._renderer.write_png(filename, self.figure.dpi.dpi.get())
TypeError: cannot return std::string from Unicode
