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...

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...
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

Building a matrix from a network >>> graph = divisi2.load('data:graphs/conceptnet _ en.graph') >>> from csc.divisi2.network import sparse _ matrix >>> A = sparse _ matrix(graph, 'nodes', 'features', cutoff=3) >>> print A ...
本文简要介绍 networkx.convert_matrix.from_numpy_matrix 的用法。 用法: from_numpy_matrix(A, parallel_edges=False, create_using=None)从numpy 矩阵返回一个图。numpy 矩阵被解释为图的邻接矩阵。参数: A:numpy 矩阵 图的邻接矩阵表示 parallel_edges:布尔值 如果为真,create_using 是多重图,而A 是整数...
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. ...
