[Matplotlib-users] imshow?

[Stephen W. <ste...@cs...>]

I'm doing something wrong, obviously, but am not sure what.  I have
Numeric 23.1 (and numarray 1.1) installed under Python 2.2 on Fedora
Core 1, and matplotlib 0.62.4.  Attempts to do an imshow() result in an
error message that "pygtk was not compiled with Numeric Python support."

I looked into this a little and the message is coming from pygtk itself,
not surprisingly.  Is there any chance you installed Numeric after
pygtk?  If so,  you might want to try reconfiguring and re-installing
pygtk.

Hope this helps,
Todd

My guess is you are using a precompiled pygtk (eg the one that ships
with FC1).  You'll probably need to compile pygtk from src, with
threads and numpy support

Alternatively, you could simply use the gtkagg backend, in which case
you won't need gtk with numpy support.

Yup.  I changed .matplotlibrc to force the GTKAgg backend and all is
more or less well.  I say this because (1) I'm using "ipython -pylab" on
both FC1 and FC2; (2) I'm using the precompiled pygtk2 on both; (3)
imshow works fine on FC2 with no .matplotlibrc file; and (4) the default
colormap on FC1 seems to be grayscale, but on FC2 it is colorful.

All systems have IPython 0.6.3 installed from Fernando's RPM and
matplotlib 0.62.4 built locally with no changes to the defaults.
