在通过NetworkX搜索子图同构时,有没有找到节点映射的方法?例如,
import numpy as np
from networkx.algorithms import isomorphism
import networkx as nx
B = [[0, 2, 1, 0, 0],
[2, 0, 1, 0, 1],
[1, 1, 0, 1, 0],
[0, 0, 1, 0, 0],
[0, 1, 0, 0, 0]]
A = [[0, 1, 1],
[1, 0, 2],
[1, 2, 0]]
G1 = nx.from_numpy_matrix(np.array(B), create_using=nx.MultiGraph())
G2 = nx.from_numpy_matrix(np.array(A), create_using=nx.MultiGraph())
GM = isomorphism.MultiGraphMatcher(G1,G2)
print(GM.subgraph_is_isomorphic())
print(GM.mapping)打印{0: 0, 1: 1, 2: 2},但这不是真的。

我找到了解决办法:
GM = isomorphism.MultiGraphMatcher(G1, G2, edge_match=lambda x, y: x[0]['weight'] == y[0]['weight'])根据源代码文档,应该为多个图指定edge_match函数。
