igraph与netwrokx的转换

igraph官网：https://igraph.org/python/#startpy
值得注意的是，安装不是所见即所得的pip install igraph，而是：

pip install python-igraph

如题，本篇文章中将介绍的内容为networkx和igraph之间的转换。

1. networkx转igraph

import networkx as nx
import igraph as ig

g = nx.karate_club_graph()
d = nx.to_pandas_edgelist(g).values
g = ig.Graph(d)
for v in g.vs:
    print(v)

2. igraph转networkx

import networkx as nx
import igraph as ig

g = nx.karate_club_graph()
d = nx.to_pandas_edgelist(g).values
g = ig.Graph(d)

t = [str(e[0])+" "+str(e[1]) for e in g.get_edgelist()]
f = nx.parse_adjlist(t)
print(f.nodes)
