About graph_draw and condensational_graph

I solved the problem by installing the python bindings for graphviz. I did not installed it as appears as optional in the documentation. I tried to draw a 250,000 nodes graph and my machine run out of memory (it has 3GB). Have you tested what is the maximum graph size to be drawn in graph-tool? Regards, Juan

About graph_draw and condensational_graph

Hi, First of all thank you for graph-tool, on my humble opinion one of the bests tools for graphs manipulation in open source. I have two basic problems I hope you can resolve. First I am trying to draw a graph using the draw_graph function, but something seems to be wrong in the code. This is my code: import sys, os from pylab import * from graph_tool.Graph import * g = load_graph("mygraph.dot") graph_draw(g, output="prueba.png") I get the following error: /usr/local/lib/python2.6/dist-packages/graph_tool/draw/__init__.pyc in graph_draw(g, pos, size, pin, layout, maxiter, ratio, overlap, sep, splines, vsize, penwidth, elen, gprops, vprops, eprops, vcolor, ecolor, vcmap, vnorm, ecmap, enorm, output, output_format, returngv, fork, seed) 239 gvg = gv.digraph("G") 240 else: --> 241 gvg = gv.graph("G") 242 243 if pos != None: NameError: global name 'gv' is not defined I am using the last release from the git repository. Is this a problem from the repository version (non stable I suppose) or is this a problem in my code or installed libraries? I had no problem during the compilation, and I have already tested other functions such as the local_clustering and seem to be working. Second. I have tried to use the condensational_graph function to compare some community_structures. But this function seems missing, is this some problem regarding with the non stable version, or it is my fault? Thank you very much. Juan

Stable release?

Ciao all- Is there any planned date for a stable release of graph-tool at this point? The current requirements, particularly GCC 4.4 and > 1 GB of ram, are out of reach for me currently, and I would love to be able to just grab a package. Cheers, Cyrus
