I have been using igraph for a few days, and it worked perfectly fine until today. When i tried to execute one of my previously working codes, i got this error:
Traceback (most recent call last): File "conductance.py", line 2, in <module>
from igraph import * File "/usr/lib/python2.7/dist-packages/igraph/__init__.py", line 30, in <module> from igraph.core import * ImportError: /usr/lib/python2.7/dist-packages/igraph/core.so: undefined symbol: igraph_community_leading_eigenvector_naive
