Hi,

That kind of things happen when your numpy version is not the same as the one used to compile graph-tool..

Maybe you can try to get the newer version of numpy and scipy (or older ones if this problem appeared after you upgraded).

Hope it helps,

Guillaume

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:

Python 2.7.6 (default, Nov 12 2013, 13:10:34)
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin

1)

ImportError: cannot import name ellipkm1

Could you help me solve this problem?


Best regards,


Sandrine
