Hi,
I'm using python-igraph (0.7.1) and when I save a graph with an integer
attribute as GraphML, attr.type= "double" is used instead of "int". See a
minimal example below.
Regards,
In [1]: import igraph as ig
In [2]: g = ig.Graph()
In [3]: g.add_vertex()
In [4]: g.vs["size"] = [1]
In [5]: g.vs[0]
Out[5]: igraph.Vertex(<igraph.Graph object at 0x7f25969f0430>,0,{'size': 1})
In [6]: g.write_graphml("test.graphml")
In [7]: %cat test.graphml
<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns
http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd";>
<!-- Created by igraph -->
<key id="v_size" for="node" attr.name="size" attr.type="double"/>
<graph id="G" edgedefault="undirected">
<node id="n0">
<data key="v_size">1</data>
</node>
</graph>
</graphml>
