Errors when using any explorer besides SliceSampler() on a turing model

[Raoul-Kima]

When I try to use any explorer other then SliceSampler I get an error saying:
KeyError: key :singleton_variable => OnlineStatsBase.Variance not found

Here's a stacktrace from AutoMALA:

Test model was:

Explorers tested were: AAPS, MALA, AutoMALA.

Here's the environment and reprex:

Yes, the Pigeons-Turing integration currently support only the SliceSampler. We hope to relax this restriction soon. Note however that the slice sampler is more general since it handles both discrete and continuous variables. If performance is critical, for now it may be better to code the target in Stan, or as a Julia function as a workaround. For these types of target, AAPS, MALA, AutoMALA do work.

Thanks for the clarification!
Shall I close this issue then, or leave it open for others so they can see it's known and being worked on? (I'm asking because it sounds a bit like you had a separate issue tracker somewhere else where this is already being tracked)

No worries! This issue is already tracked by #160 so feel free to close this one.
