I don't have the prior for how the layers should be grouped together. I suppose I need equation 18 also? Are all of these implemented in graph-tool? If so, can you specify the functions in graph-tool for this? It doesn't seem the LayeredBlockState constructor takes multiple graphs or multilayer graphs as input.

OK. Fig 1 and its legend in this paper (http://ieeexplore.ieee.org/document/7442167/) is a summary of what I just stated before.
They describe a multilayer SBM, much like the one which is implemented in graph-tool (the main difference is that in graph-tool the model is nonparametric).
If you want to find what they call "strata", i.e. groups of layers, all you need to do is group layers together, such that the description length, with the addition of a term, as described in Eq. 17 of http://dx.doi.org/10.1103/PhysRevE.92.042807.
