在使用时nx.connected_component_subgraphs(G)[0],遇到报错: TypeError: 'generator' object has no attribute '__getitem__' 解决方法: 从1.9版本开始,connected_components的输出不再是list形式,而是generator 如果仍需使用list输出,可以采用 list(connected_components(G)) 输出 另外, 获取最大连通子图时如果可以...

使用networkx的connected_components函数获取所有连接的组件: 代码语言:txt 复制 components = list(nx.connected_components(G)) 创建集团对象并将连接的组件添加到集团中: 代码语言:txt 复制 集团= [] for component in components: 集团.append(list(component)) 完成以上步骤后,你将得到一个包含所有连接的组件的集...
获取连通分量(nx.connected_component_subgraphs(G),返回的是列表,但是元素是图,这些分量按照节点数目从大到小排列,所以第一个就是最大的连通分量。
Have you noticed that 'connected_component_subgraphs' is removed in 'networkx' version 2.4?Contributor Jessime commented May 30, 2020 I have; networkx is specifically pinned to avoid this problem until I get a chance to fix it. https://github.com/CalabreseLab/seekr/blob/master/setup.py#...
Gc = max(nx.connected_component_subgraphs(G), key=len)为了以后查此问题的人方便！

由于整个网络过于庞大,我们会将整个网络模型G拆为多个子网络放到subgraphs中。 subgraphs = [gforginnx.connected_component_subgraphs(G.to_undirected())] subgraphs= sorted(subgraphs, key=lambdax: x.number_of_nodes(), reverse=True)print([s.number_of_nodes()forsinsubgraphs[:10]]) ...
