It doesn't look like a faulty X setup, and since you *do* get a window, it's unlikely it's a Tkinter problem.
The fishy thing here is that _tkagg should be a C extension, have a .so file extension and have only the following members --> >>> dir(_tkagg) ['__doc__', '__file__', '__name__', '_pyobj_addr', 'tkinit'] tkagg (without the underscore), on the other hand, is a true Python module, would have a .pyc extension and all of the members you posted. So, somehow, tkagg got renamed to _tkagg on your system. I'm not sure how the build script may have done that. Does removing /usr/lib/python2.5/site-packages/matplotlib/backends/_tkagg.pyc help? (It's generally safe to remove .pyc files since they are regenerated by the Python compiler). Do you have a _tkagg.py sitting in that directory? Did you build matplotlib from the source tarball, a Gentoo port (or whatever they're called), or some other way? If you built yourself, (even if the above suggestion worked), could you try cleanly rebuilding again by: 1. deleting the build directory under the source tree 2. deleting /usr/lib/python2.5/site-packages/matplotlib 3. "python setup.py install" and let us know if that worked? Cheers, Mike Darren Dale wrote: > Do you have the tk-devel packages installed?
