[Matplotlib-users] Installing matplotlib

[<rei...@gm...>]

Hello,

it's me again, I found my mistake, I specified the wrong path when  
installing pygtk. But now, I have a problem installing matplotlib. When  
I type

python setup.py build

it terminates with:

Traceback (most recent call last):
   File "setup.py", line 125, in ?
     try: import gtk
   File  
"/Library/Frameworks/Python.framework/Versions/2.3//lib/python2.3/site- 
packages/gtk-2.0/gtk/__init__.py", line 37, in ?
     from _gtk import *
RuntimeError: could not open display

What is going wrong? I have no idea...
Thanks
Reik

Actually I think this is fixed in CVS, isn't it?

All the best,

I think so.  In my cvs tree in setup.py, I have

if BUILD_GTKAGG:
    try:
        import gtk
    except ImportError:
        print 'GTKAgg requires pygtk'
        BUILD_GTKAGG=0
    except RuntimeError:
        print 'pygtk present but import failed'


If X is not present, they get the runtime error, and in this case GTK
will still build, right?

But you'll still need X to run the GTK backend....

This is an annoying build issue that hopefully we'll resolve before
too long.  I assume you are building from the Terminal shell is OSX.
You'll need build and run matplotlib from the X terminal

Hope this helps,

First of all, thanks for your help.
I made several mistakes, which I fixed: I installed matplotlib as root =20=

and from xterm. The installation process worked out fine,the output of
 >python setup.py build
was
TKAgg requires TkInter
running build
running build_py
running build_ext

which is ok, I think. At least it doesn't say "require pygtkg" anymore. =20=

The
 >sudo python setup.py install
ran without mistakes.

BUT: When  I start python, and I want to import matplotlib.matlab, this =20=

happens:

Python 2.3.4 (#2, Nov 14 2004, 18:39:27)
[GCC 3.3 20030304 (Apple Computer, Inc. build 1495)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
 >>> import matplotlib.matlab
Could not load matplotlib icon: Couldn't recognize the image file =20
format for file =20
'/Library/Frameworks/Python.framework/Versions/2.3/share/matplotlib/=20
matplotlib.svg'
Traceback (most recent call last):
   File "<stdin>", line 1, in ?
   File =20

packages/matplotlib/matlab.py", line 163, in ?
     from backends import new_figure_manager, error_msg, \
   File =20

   File =20

packages/matplotlib/backends/backend_gtkagg.py", line 16, in ?
     from _gtkagg import agg_to_gtk_drawable
ImportError: No module named _gtkagg


I thought,  everything ist ok, when the installation is completed =20
successfully - obviously I am wrong. But what now? I am lost...
Thanks for your help
