Hello,

I was wondering that can we customise sampling progressbar during inference by Turing.jl?

```julia
 sample(model, NUTS(1000, 0.65), MCMCThreads(), 10000, 3, progress = true)

```

At the moment it shows progress after 1/3 sampling is done. I want it to report after every 1/10. Is this possible?

Hi @Sahil_Khan, this is a longstanding issue with Turing and the summary is that it’s generally not possible right now, see [Progress reporting in parallel sampling · Issue #2264 · TuringLang/Turing.jl · GitHub](https://github.com/TuringLang/Turing.jl/issues/2264) and [More useful logging when sampling multiple chains · Issue #82 · TuringLang/AbstractMCMC.jl · GitHub](https://github.com/TuringLang/AbstractMCMC.jl/issues/82) for more discussion.

What about saving chain internally or printing some information about likelihood during run?. So, one gets some information whats going on for long runs.

How can i do this?

Since quite a few people have clicked the link I posted above, I should add that the received wisdom of it being impossible was not fully accurate, and since about a year ago sampling with `MCMCThreads()` now gives much more informative progress bars, with some customisation options to boot. There are some examples with videos at [Progress bars when sampling multiple chains - Pull Request #168 - TuringLang/AbstractMCMC.jl - GitHub](https://github.com/TuringLang/AbstractMCMC.jl/pull/168).

There are also callbacks that one can use to log / visualise more information during runs, there are some docs here [Callbacks · AbstractMCMC](https://turinglang.org/AbstractMCMC.jl/stable/callbacks/).
