1、我使用的是networkx 3.1 2、networkx 3.0开始就删除了from_numpy_matrix() 详见官方文档:NetworkX 3.0 — NetworkX 3.1 documentation 3、from_numpy_array()的使用from_numpy_array — NetworkX 3.1 documentation
这是因为NetworkX需要知道如何将DataFrame中的数据映射到图的节点和边。如果你需要创建一个空的图并手动添加节点和边,可以使用nx.Graph或nx.DiGraph类。这些类没有内置的方法来从NumPy矩阵创建图,但你可以使用add_edge或add_nodes_from方法来手动添加节点和边。以下是一个示例代码: import networkx as nx # 创建一...
这提供了许多库和组件，用于简化不同的任务，包括创建图形和显示。NetworkX 代表了一个高效的 Python ...
遇到“module 'networkx' has no attribute 'from_numpy_matrix'”这个错误,通常是因为你正在使用的NetworkX版本已经不再包含from_numpy_matrix这个属性或方法。以下是针对这个问题的详细解答和解决方案: 1. 确认from_numpy_matrix属性的存在 在NetworkX的较新版本中,from_numpy_matrix方法已经被移除。这是因为NetworkX团...

I recently needed an implementation of the A* algorithm in Python to find the shortest path between two points in a cost matrix representing an image. Normally I would simply use networkx, but for graphs with millions of nodes the overhead incurred to construct the graph can be expensive. ...
