我正在尝试使用
读取GML文件nx.read_gml('test.gml')
我查看了networkx read_gml()文档。据说 GML规范说文件应该是ASCII编码的，所以当我写GML时，我使用以下
reload(sys)
sys.setdefaultencoding('ascii')
nx.write_gml(g, fname + '.gml')
test.gml的内容如下。

答案 0 :(得分：0)
我使用当前的networkx-2.0b1测试版进行了测试，结果正常。
In [1]: import networkx as nx
In [2]: G = nx.read_gml('test.gml')
In [3]: nx.write_gml(G,'test2.gml')
In [4]: H = nx.read_gml('test2.gml')
In [5]: nx.is_isomorphic(G,H)
# True
如果您没有使用该版本，也许您可以更新并测试？
