AttributeError: module ‘networkx‘ has no attribute ‘from_numpy_matrix‘解决方法_module 'networkx' has no attribute 'from_numpy_mat

在我学习louvain算法时，运行了这样一段代码

from communities.algorithms import louvain_method
from communities.visualization import draw_communities
import numpy as np
adj_matrix = np.array([[0, 1, 1, 0, 0, 0],
                       [1, 0, 1, 0, 0, 0],
                       [1, 1, 0, 1, 0, 0],
                       [0, 0, 1, 0, 1, 1],
                       [0, 0, 0, 1, 0, 1],
                       [0, 0, 0, 1, 1, 0]])
 
communities, frames = louvain_method(adj_matrix)
draw_communities(adj_matrix, communities)

运行报错

AttributeError: module 'networkx' has no attribute 'from_numpy_matrix'

问题原因及解决方案：

在 .networkx 3.0 中，变更日志显示以下内容“删to_numpy_matrix & from_numpy_matrix (#5746)” https:/.networkx.org/documentation/stable/release/release_3.0.html您必须降级.networkx 或改用G=nx.from_numpy_array(A) 。 https:/.networkx.org/documentation/stable/reference/readwrite/matrix_market.html
