Hi!
what is the graph-toolic way of working with a GraphView other than for drawing?
I find the filtering functionality pretty neat and would like to do things like
babo = load_graph('babonet.gt')
babo_in_hist = vertex_hist(babo, 'in')
chabo = GraphView(g, efilt=lambda e: g.ep.chabo_prop[e] == 'WISSEN_WER')
chabo_in_hist = vertex_hist(chabo, 'in')
Yet babo_in_hist == chabo_in_hist evaluates to True, which makes sense because chabo knows who the babo is (they share the same basis data).
I can come up with a way of building an extra network based on the GraphView, but this seems like something somebody else has already needed so I figured I better ask first (obviously after having checked the mailing list archive ;) )
Have a nice weekend everybody!
Juan Dominguez-Moran

Hi,
I don't think you're supposed to do "gt.centrality.eigenvector(MyGraph)". Did you try
"gt.eigenvector(MyGraph)"?

Yes, I tried this too but it doesn't work.
*gt.eigenvector(MyGraph)* doesn't work. It's not listed in the list of
modules inside graph_tool package.
Also documentation specifically mentions
*graph_tool.centrality.eigenvector(g, weight=None, vprop=None,
epsilon=1e-06, max_iter=None)*
that is the command has to be called inside the centrality module of graph
tool package.

Sir,
I am unable to import centrality function from the graph tool package
*import graph_tool as gt*
*gt.centrality.eigenvector(myGraph)*
gives the following error:
*AttributeError: module 'graph_tool' has no attribute 'centrality'*
I tried after restarting my Spyder IDE but the issue remains
I am using graph tool version
'2.27 (commit ce258562, Thu Jun 28 14:29:44 2018 +0100)'

I'd like to use the "add_edge_list" function to add edges to my graph, and
simultaneously assign a value for an edge property map for each of the added
edges.
When I try the following example (with no edge property map information)
works fine:
elist1 = np.array([[0,1], [1, 2]]) #edge list with no value for edge
property map data (only the source and target for the edges)
g = gt.Graph()
my_eprop = g.new_edge_property('bool')
g.add_edge_list(elist)
But with the following example, I get the error below:
elist2 = np.array([[0,1, 1], [1, 2, 0]]) #edge list with edge property map
value in 3rd column
g = gt.Graph()
my_eprop = g.new_edge_property('bool')
g.add_edge_list(elist2, eprops=my_eprop)
Error:
