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

如果你在使用networkx库中的from_numpy_matrix函数时出现AttributeError: module 'networkx' has no attribute 'from_numpy_matrix'错误，通常是因为你的networkx版本太低，该函数在较早的版本中可能不存在。你可以尝试更新networkx库到最新版本来解决这个问题，可以使用以下命令：

pip install --upgrade networkx

如果你使用的是conda环境，则可以使用以下命令：

conda update networkx

更新完成后，再次尝试运行from_numpy_matrix函数应该就不会出现该错误了。

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

这个错误通常是因为你的NetworkX库版本过低导致的，from_numpy_matrix是NetworkX 2.1版本之后才开始支持的函数。可以通过以下方法解决该问题：

1.升级NetworkX库版本到2.1以上：

pip install networkx --upgrade

2.使用其他方法替代from_numpy_matrix函数，如下面的代码所示：

import numpy as np
import networkx as nx

adj_matrix = np.array([[0, 1, 1], [1, 0, 1], [1, 1, 0]])
G = nx.from_numpy_array(adj_matrix)

这段代码将邻接矩阵转换为NetworkX图对象，可以代替from_numpy_matrix函数。

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

This error occurs when you try to use the `to_numpy_matrix` function from the `networkx` module, but the function is not found. This may be due to using an older version of the module where the function was not yet implemented, or it may have been removed in a newer version of the module.

To fix this error, you can try updating the `networkx` module to the latest version, or you can use an alternative method to convert the graph to a numpy matrix. One option is to use the `adjacency_matrix` function from the `scipy` module, which can be used to create a sparse matrix representation of the graph. Another option is to manually create a numpy matrix by iterating over the nodes and edges of the graph.
