'Graph' object has no attribute 'vcount' #58

Hai, I have tried Leiden package. When running it with the famous 'karate club' network, it produced an error like Graph' object has no attribute 'vcount'. What will be the reason?????

import leidenalg
import igraph as ig
import networkx as nx

G = nx.karate_club_graph()
part = leidenalg.find_partition(G, leidenalg.ModularityVertexPartition)

The object G is a networkx object, not an igraph object. In the most recent versions of igraph, you can obtain an igraph object using from_networkx: G2 = igraph.Graph.from_networkx(G). You can then apply leidenalg.find_partition to G2 instead of G.
