Hi,

I‘m relying on the deb package, so I’ll have to wait for next release. Meanwhile, here is a workaround for any one interested:

def _get_valid_mask(graph):
    '''Mask over valid edges '''
    valid = graph.new_edge_property('bool')
    valid.a[:] = 0
    for edge in graph.edges():
        valid[edge] = 1
    return valid

valid = _get_valid_mask(graph)
graph.set_edge_filter(valid)

edge_prop.fa.shape[0] == graph.num_edges()

Thanks for the fast answer,

Best,

Guillaume

Hi Tiago, hi all,

When an edge is removed from a graph, it still occupies a place in the graphs EdgePropertyMap, leading to the following being |False|:

|edge_prop.a.shape[0] == graph.num_edges()|

Is there a way to circumvent this?

If you use a recent version from git, this can be obtained by getting
the filtered array, with the .fa attribute:

    edge_prop.fa.shape[0] == graph.num_edges()

Best,
Tiago
