Will require new release of AdvancedHMC TuringLang/AdvancedHMC.jl#160, once it's in this should be good to go. Works for me locally.

[xukai92]

The new release is there.

[Vaibhavdixit02]

Thanks @xukai92!

[ChrisRackauckas]

@xukai92 can we get some help figuring out what Turing is trying to iterate?

[xukai92]

Do you mean why we do this DynamicPPL thing?

[Vaibhavdixit02]

@ChrisRackauckas that happens because https://github.com/TuringLang/Turing.jl/blob/master/src/inference/Inference.jl#L856's types, the MvNormal is <: both Distribution and MultivariateDistribution, but the MultivariateDistribution method does not accept AbstractArray type, so when you don't matrixize in the dot_tilde call here, it can't iterate. On changing it though, I am encountering another error which I can't understand https://travis-ci.org/JuliaDiffEq/DiffEqBayes.jl/jobs/635608371?utm_medium=notification&utm_source=github_status

It's might be related to what @mohamed82008 is trying to fix.

[mohamed82008]

Yes that looks related to TuringLang/Turing.jl#1043. I will take a look next week. Please open an issue in Turing to track it, happy to investigate when I get some time.
