Hello,
I am trying to read a graphml format file in igraph using python shell.
This is the command I run:
g = igraph.read("mumbaiFinal.graphml")
Earlier this seemed to work fine, however now suddenly I am getting
following error:
---------------------------------------------------------------------------
InternalError Traceback (most recent call last)
/home/stuti/project/mumbai/<ipython-input-56-119be08d9a80> in <module>()
----> 1 g = igraph.read("mumbaiFinal.graphml")
/usr/local/lib/python2.7/dist-packages/igraph/__init__.pyc in
read(filename, *args, **kwds)
3986 @param filename: the name of the file to be loaded
3987 """
-> 3988 return Graph.Read(filename, *args, **kwds)
3989 load=read

/usr/local/lib/python2.7/dist-packages/igraph/__init__.pyc in Read(klass,
f, format, *args, **kwds)
2171 raise IOError("no reader method for file format: %s" %
str(format))
2172 reader = getattr(klass, reader)
-> 2173 return reader(f, *args, **kwds)
2174 Load = Read
2175
InternalError: Error at foreign-graphml.c:1134: xmlParseEntityRef: no name
, Parse error
In the graphml file I have defined the attributes as keys:
<key id="latitude" for="node" attr.name="latitude" attr.type="double"/>
<key id="longitude" for="node" attr.name="longitude" attr.type="double"/>
<key id="label" for="node" attr.name="label" attr.type="string" />
<graph edgedefault="directed">
Could you please help me fix this problem? I am not able to create a graph
itself, and thus not able to proceed further. Any other method/hack to
create graph using graphml file would also do.
Thank you.
