[Matplotlib-users] Can't run matplotlib without tk backend on windows?
Hi, after having correctly compiled matplotlib, now is time to test
something (I need at least to get it something working before I can
start hack it autonomously =). Unfortunately, it's not usable: it
complains about not being able to load _tkagg module. The fact is I
don't want tkagg backend at all! Here is the backends dependencies
detect log:
OPTIONAL BACKEND DEPENDENCIES
libpng: found, but unknown version (no pkg-config)
Tkinter: no
* Tkinter present, but header files are not found.
* You may need to install development packages.
wxPython: no
* wxPython not found
Gtk+: gtk+: 2.10.11, glib: 2.12.11, pygtk: 2.10.6,
pygobject: 2.12.3
Qt: no
Qt4: no
Cairo: 1.2.6
As it should be clear, I want to use the a gtk+ aware backend, and
initially in fact I used a customized setup.cfg; seeing the error I
tryed deleting the customized setup.cfg, but without results. Is
there some problems with backend selection on windows platform?
I hope gtk+ backends are supported. Follows 2 traces of the error
running an ipython shell and a test python program (it works on
linux).
Any help is appreciated.
Thanks,
Francesco

Re: [Matplotlib-users] Can't run matplotlib without tk backend on windows?
You need to set a different backend in your matplotlibrc or specify it first.
import matplotlib
matplotlib.use('Agg')
You can also run scripts passing the backend:
python lab1_ex2.py -dAgg

setup.py attempts to select the appropriate backend for you, based on what
backends were available at build time. That selection is written into the
default matplotlibrc file, which resides in
site-packages/matplotlib/mpl-data. If matplotlib finds another matplotlibrc
file (for example, in the current working directory, in $HOME/.matplotlib,
etc), then it will use those settings instead. I would guess that is the
source of the problem.
