I am new to igraph and use python igraph 0.6.5 in ubuntu python 2.7.
I have my own pajek file I loaded into python, and ran community detection
algorithm and got the following dendrogram
>>> print(dendrogram)Dendrogram, 1335 elements, 314 merges
But when I tried to run as_clusting, I got the following error:
>>> clusters = dendrogram.as_clustering()Traceback (most recent call last):
>>> File "<stdin>", line 1, in <module> File
>>> "/usr/lib/python2.7/dist-packages/igraph/clustering.py", line 959, in
>>> as_clustering num_elts - n)igraph._igraph.InternalError: Error at
>>> community.c:767: `steps' to big or `merges' matrix too short, Invalid value
How do I debug from here? My pajek file's Vertices are not continuous. Would
that create a problem?
Thanks,
Xiao
