Hi everyone,
I would like to develop a Tkinter GUI application for a course that I am
teaching this semester that has an embedded matplotlib plot. I was hoping to
have this application work with both the Mac OS X and Windows versions of
Enthought Python Distribution v. 6.0.0. As a starting point, I was going to
try the user interface examples, embedding_in_tk.py and embedding_in_tk2.py, on
the matplotlib website. I have changed my default backend from WXAgg to TkAgg
in my matplotlibrc file. With the Mac OS X version of EPD 6.0.0, the examples
seem to work just fine. However, with the Windows version, I get the following
import error:
C:\Documents and Settings\bminch\Desktop>python embedding_in_tk2.py
Traceback (most recent call last):
File "embedding_in_tk2.py", line 6, in <module>
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg, NavigationT
oolbar2TkAgg
File "C:\Python26\lib\site-packages\matplotlib\backends\backend_tkagg.py", lin
e 8, in <module>
import tkagg # Paint image to Tk photo blitter extension
File "C:\Python26\lib\site-packages\matplotlib\backends\tkagg.py", line 1, in
<module>
import _tkagg
ImportError: No module named _tkagg
C:\Documents and Settings\bminch\Desktop>
The same thing happens when I invoke ipython with the -pylab option, although
with a traceback that is a bit longer. At the bottom of it is the same import
error, "No module named _tkagg."
Has anyone experienced similar problems with the TkAgg backend under the
Windows version of EPD 6.0.0? Can anyone suggest how to fix the problem?
Thanks,
Brad Minch.
