python - 属性错误 : module 'networkx' has no attribute 'connected_component_subgraphs'

Question

B = nx.Graph()
B.add_nodes_from(data['movie'].unique(), bipartite=0, label='movie')
B.add_nodes_from(data['actor'].unique(), bipartite=1, label='actor')
B.add_edges_from(edges, label='acted')

A = list(nx.connected_component_subgraphs(B))[0]

尝试使用 nx.connected_component_subgraphs(G) 时出现以下错误.
在数据集中有两个库(电影和 Actor )，它的形式是二分图。
我想获得电影节点的连接组件。

Answer 1

这在 2.1 版中已被弃用，最终在 2.4 版中被删除。
见 these instructions

Use (G.subgraph(c) for c in connected_components(G))

Or (G.subgraph(c).copy() for c in connected_components(G))
