get_out_degrees function issue
by Davide Baù 10 Nov '17

Hi, I'm trying to use the function "get_out_degrees", but I get following error: AttributeError: 'Graph' object has no attribute 'get_out_degrees' The graph I generated is a directed graph: <Graph object, directed, with 396 vertices and 10042 edges at 0x7fb5c15c5690> The gt version is the 2.18 (Ubuntu Trusty): '2.18 (commit 37996a0a, Thu Jul 21 17:56:14 2016 +0200)' Any idea of what I'm doing wrong? Thanks a lot! Davide

Segmentation fault (core dumped) when running minimize_blockmodel_dl(g, overlap=True)
by Sanja Šćepanović 09 Nov '17

Hi All, I am experiencing the problem that I always get Segmentation fault (core dumped) and my program does not finish when running state = minimize_blockmodel_dl(g, overlap=True) When overlap=False, there is no problem. I have the 2.24 graph-tool version installed from Ubuntu repo. I tried this with both python2.7 and python3 -- in both cases, I get the segmentation fault error. Also, this is not due to the size of my graph, I tried with a toy example with only 10 nodes, it still happens. Any ideas what I could do are very much appreciated. Thanks, Sanja

disassortative constraints?
by Peter Straka 01 Nov '17

01 Nov '17

Hello, so clabel() and pclabel() serve as constraint labels: different values for nodes mean that nodes are placed in different groups, i.e. this is an assortative constraint (all nodes with the same label are place in one group). Is there a way to do a disassortative constraints: nodes with the same label are placed in different groups?
