Is it illegal for a police officer to buy lottery tickets? TGF, To do it with numpy.random.rand, generate the random array, threshold it with the probability you want, and then pass it to Graph.Adjacency: adj = numpy.random.rand(edges, edges) adj[adj > 0.999] = 1 # sets everything over 0.999 to 1 adj[adj <= 0.999] = 0 # sets everything below to 0 graph = Graph.Adjacency(adj) This generates a directed graph, where adj [i, j] tells you whether there's an edge from i -> j.
