但是，当我试图读取GML时，networkx抛出下面的异常，抱怨

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 0: ordinal not in range(128)

我能知道怎么做吗

1. 正确阅读GML？有没有可能知道GML的哪一行导致了这个错误？在
2. 在不引起上述错误的情况下编写GML？在

我用当前的networkx-2.0b1测试版测试了它，它工作正常。在

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

如果您不使用该版本，也许您可以更新和测试？在
