This doesn’t answer your question directly, but I recommend [Turing](https://github.com/TuringLang/Turing.jl) or [DynamicHMC](https://github.com/tpapp/DynamicHMC.jl), as they are more activity maintained and developed. Turing in particular is geared towards machine learning. You might find some useful information in this [thread](https://discourse.julialang.org/t/bayesian-neural-network-multiclass-classification-in-turing-jl-and-flux-jl/21134/3).
