import gv about python-graph

You need to install graphviz and configure your Python path to include the 
bundled
Python module.

I have Graphviz2.20 installed for Windows XP but am unsure what the Python 
module is
I should be looking for.  Can you advise?

I'm not familiar with Graphviz for Windows, but you probably need to add the 
location
of the module to the import path.

On Linux, I do this:
import sys
sys.path.append('/usr/lib/graphviz/python/')

Replace /usr/lib/graphviz/python/ with the location of the gv module on Windows.

Probably a path problem. Try this before importing the gv module:
import sys
sys.path.append('/usr/lib/graphviz/python/')    # 32-bits
sys.path.append('/usr/lib64/graphviz/python/')  # 63-bits

This is what I do in Fedora. Maybe Ubuntu places the module on na different 
location.

You can create .dot files and then use the command-line tools distributed with
graphviz to draw the images.

To make it work at Ubuntu 9.10 (after installing graphviz, python-graph, 
libgv-python
and python-pygraphviz) it was necessary this ugly substitution for the "_gv.so" 
library:

sudo su
cd /usr/lib/pyshared/python2.6 mv _gv.so _gv.so-
ln -s libgv_python.so _gv.so

Than you have to use: sys.path.append('/usr/lib/pyshared/python2.6')

It appears that graphviz for windows has no python bindings, or they are not 
included with the installer, and not available elsewhere.

Furthermore, I can find no mention of libgv-python (the library which gv is 
from, I 
think) *ever* being available on windows.

Has this library ever actually been tested on windows?

@nagini, thank you. Your solution works. Although I could not get it working on 
64 bit one. may be its ubuntu 10.04 or 64 bit.

I've already done what Nagini said, but i've got:


  File "/usr/lib/pymodules/python2.6/gv.py", line 25, in <module>
    _gv = swig_import_helper()
  File "/usr/lib/pymodules/python2.6/gv.py", line 17, in swig_import_helper
    import _gv
ImportError: No module named _gv

I don't see any _gv in "/usr/lib/pymodules/python2.6/" Any suggestion?

I know what's the problem... i should use: sudo ln -s libgv_python.so _gv.so

Can't get this to work on OS X Snow Leopard. Have built graphviz from scratch, 
have intalled py??-pygraphviz packages via MacPort and I still can't neither 
get python to find the gv module nor find the _gv.so library.
