当你遇到 networkxerror: found infinite path length because the graph is not connected 这个错误时,通常意味着你正在尝试在一个未连接(即存在孤立的节点或节点之间不存在路径)的图上运行一个需要遍历所有节点的算法。这种情况下,算法可能无法找到有限长度的路径来连接所有节点,从而导致错误。 下面我将按照你提供的...

You can remedy this by first finding out if your Graph “is connected” (i.e. all one component) and, if not connected, finding the largest component and calculating diameter on that component alone. Here’s the code: # If your Graph has more than one component, this will return False...

G=nx.Graph() 在NetworkX中,图由节点(顶点)和连接节点的边(链接、连线等)组成。节点可以是任何可散列对象,例如数字或字符串。 2. 节点 可以使用add_node()方法将节点添加到图中。例如,添加一个值为1的单个节点: G.add_node(1) 也可以使用add_nodes_from()方法一次性添加多个节点。例如,添加节点2和3: ...
