Hello, Thank you for your suggestions. Actually, there were 2 versions of scipy and numpy installed on my computer. So, I uninstalled and re-install everything (scipy, numpy, graph_tool). Unfortunately, I observe the same problem. I will now contact the macports maintainers, as you suggest.

Dear graph_tool users,
I try to use graph_tool on my Mac OS X 10.6.8. I used Macport to install py-27-graph-tool and it seems to work perfectly. But now, when I try to import graph_tool, I have successively 2 errors:

// Could you help me solve this problem?
Do you observe the sample problems simply by importing scipy, without graph-tool? For instance: >>> import scipy >>> import scipy.stats If you observe the same problem, then clearly the problem would be with scipy. You should try simply re-installing it. If you still have the same problems afterwards, I suggest you contact the macports maintainers, and report a bug: https://trac.macports.org/auth/login/?next=/newticket Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de> _______________________________________________ graph-tool mailing list graph-tool@skewed.de http://lists.skewed.de/mailman/listinfo/graph-tool
