Thanks. I ran the Simple Hello World program (section 25.1.2.2 at http://docs.python.org/library/tkinter.html) without any problem, so I guess Tk installation itself is ok.
Someone has experience with getting matplotlib work with Tk?

Just based on the traceback, the problem seems to be in Tk - does anything in tk work for you? (e.g. any of the builtin python gui stuff) You might try installing wx and changing your matplotlibrc file to have the line “backend:WxAgg” in it. I’ve never tried using the wx backend on windows (anyone done this?), but presumably it should work…

Subject: Re: [Matplotlib-users] problem with import pylab
This is not just a problem on Windows. I have exactly the same problem when trying to use pylab with the SAGE package on my Mac OS X 10.4. I have put up questions on the SAGE support group, but have not gotten any replies. I did some googling and recall that someone on a group a while back said this was a basic problem with matplotlib. I cannot find that message, but the idea was that matplotlib was building only for file saving of graphics, not for interactive. I built my SAGE package from source so that might be right. I have a separate python framework that I use regularly and that has no problems. It's been a long time since I installed it from a binary that I don't remember if I had a problem with it, too. Unfortunately the version is different from SAGE's and I cannot just use the _tkagg module.
My error message:
/Applications/sage/local/lib/python2.6/site-packages/matplotlib/
backends/tkagg.py in <module>()
Does anyone know how to fix the tkagg interactive
plotting in matplotlib?
I have a Mac Book Pro, Mac OS X 10.4. I installed SAGE (a symbolic math
package with Python2.6), but got the following error when trying to import
pylab:
/Applications/sage/local/lib/python2.6/site-packages/matplotlib/backends/backend_tkagg.py
in ()
6
7 import Tkinter as Tk, FileDialog
----> 8 import tkagg
Paint image to Tk photo blitter extension
9 from backend_agg import
FigureCanvasAgg
10
/Applications/sage/local/lib/python2.6/site-packages/matplotlib/backends/tkagg.py
in ()
2 import Tkinter as Tk
3
4 def blit(photoimage, aggimage,
bbox=None, colormode=1):
5 tk = photoimage.tk
6
ImportError: No module named _tkagg
It appears this is matplotlib problem.
Some googling turned up a web discussion where it was
suggested that this is a matplotlib problem, not a SAGE one. The recent thread
“[Matplotlib-users] problem with import pylab” suggests that,
too. I’ve found a few comments
online, but the “fixes” are all for Linux platforms.
Does anyone know how to get TKagg interactive working
on Mac OS X? It appears to revolve
around getting the importable library _tkagg in place. Maybe other things, too.
