Networkx无法读取我的gml文件：输入不是AScienceODED

Question

我想用networkx读取我的gml文件

import networkx as nx
G = nx.read_gml('test.gml')

但我总是犯同样的错误：

networkx.exception.NetworkXError: input is not ASCII-encoded

我已经尝试将networkx降级到1.9.1版，但仍然不起作用

这里是我的gml文件的开头：

<?xml version="1.0" encoding="UTF-8"?>

通过阅读文档networkx.read_gml()

The GML specification says that files should be ASCII encoded, with any extended ASCII characters (iso8859-1) appearing as HTML character entities.

尝试使用类似于以下代码的方法重新绘制图形，但要使用您的数据

g = nx.DiGraph()
g.add_nodes_from([1, 2, 3, 4, 5, 6, 7, 8, 9])
g.add_edges_from([(1,2), (2, 1),
                  (1, 3),(3, 1),
                  (3, 4), (4, 3),
                  (4, 5), (5, 4),
                  (4, 6), (6, 4),
                  (6, 7), (7, 6),
                  (7, 8), (8, 7),
                  (1, 9), (2, 9),(3, 9), (4, 9),(5, 9), (6, 9),
                          (7, 9), (8, 9),
                  ])
nx.write_gml(, 'test.gml')
