Hi Tiago, I am a new user for Graph Tool. I was trying to do a fitting approach for a graph. And to measure the goodness of fit, I intend to use log of likelihood score for the generated graph and the real graph. For this, I needed to calculate the probabilities of each edge existing in the generated graph. However, when I use the 'get_edge_prob' function for BlockState, I get values which are greater than 0 for an edge existing. Which should not be possible since log(prob) <= 0. It is supposed to return 'unnormalised log probability' of the edge. Can you please clarify?
