Dear Filip,

The vertex_attrs dictionary should map attribute names to the list of  
attribute values. If  you use the dictionary above, igraph does not  
know the attribute name to which it should map the nodes[] array. A  
better solution is this:

>>> vattrs = {"node": nodes}

This maps the "nodes" list (or more precisely a shallow copy of that)  
to an attribute called "node":

>>> g = Graph(n=2, edges=[(0,1),(0,2)], directed=True,  
vertex_attrs=vattrs)
>>> print g.vs["node"]
[<__main__.Node instance at 0x192a3a0>, <__main__.Node instance at  
0x192a300>, <__main__.Node instance at 0x192a378>]
