After reading your "Nonparametric weighted stochastic block models"  paper and trying weighted NSBM model. I'm trying to find inferred distribution (mixed) for weights (edge-covariates). How can I get them from the BlockState object? 
I need it to repeat your graphical analysis on different weight transforms from the paper.
I guess somehow I can restore the "the marginal covariate distribution between groups r and s" from resulted object. 

Thank you,
