Dear Tiago, When I use this, there is a error:

What are the reasons ? Thank you for your help.
Looks strange... Please send a complete (minimal) example program so I can see what is going on. Also please tell me what operating system and version of graph-tool you are using. Cheers, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
