I think it is a useful feature for all samplers, which would fit nicely here.
To slightly widen the scope of this issue, we can also consider saving/restoring sampler states (e.g. step-size and preconditioning matrix of HMC).

Saving in what sense? This would all be included in the state
, no?
Yes, I think that's one of the things that could/should be moved from DynamicPPL/Turing to AbstractMCMC (maybe I misremember but it feels like there was also some discussion in some issue or PR a while ago?).
It would be nice to move have something similar to
resume_from
that we have in DPPL (https://github.com/TuringLang/DynamicPPL.jl/blob/217b8cc3a0fbee96049b90a53f5db9f2a586ba96/src/sampler.jl#L84-L95) in AbstractMCMC.In particular, by default, it shouldn't be an issue to just make
assuming that the
resume_from
corresponds to the samplerstate
.Thoughts @devmotion @cpfiffer @yebai ?
