Graphml解析错误 [英] Graphml parse error

问题描述

我试图使用python和igraph库创建一个graphml文件.我可以使用以下方法构造igraph的图形对象并将其写入文件:

g.write_graphml("mygraph.graphml")

一切似乎都成功了，但是当我尝试使用以下命令将文件读回到python时:

g = Graph.Read_GraphML('mygraph.graphml')

我收到此错误:

igraph.core.InternalError: Error at .\src\foreign-graphml.c:1024: 
Input is not proper UTF-8, indicate encoding ! Bytes: 0xA0 0x3C 0x2F 0x64

请问该如何解决? 非常感谢.

解决方案

我已经看到了库源代码.我认为库只能输出UTF-8 XML编码.因此，所有字符都必须使用UTF-8编码，并且如果文件中包含某些非UTF-8字符，则会引发错误.

解决方案:

您应按照此处

希望获得帮助.

I tried to create a graphml file using python and igraph library. I can construct igraph's graph object and wrote it to a file using:

g.write_graphml("mygraph.graphml")

Everything seems to be successful but when I tried to read the file back to python using:

g = Graph.Read_GraphML('mygraph.graphml')

I got this error:

igraph.core.InternalError: Error at .\src\foreign-graphml.c:1024: 
Input is not proper UTF-8, indicate encoding ! Bytes: 0xA0 0x3C 0x2F 0x64

How can I solve this, please? Thank you very much.

解决方案

I already see the libary source code. I think library can output only UTF-8 XML Encoding. So all character must be UTF-8 encoding and if some non-UTF-8 character contains in file, Errors will be raised.

The Solution:

You should convert all string in your python application to UTF-8 encoding before use as describe here

Hope this help.
