Whenever I try to sample multiple chains (njobs \> 1), the output gets printed on the console instead,

Not a huge issue but perhaps something to add to the list? I feel like the combination of notebook + windows platform often throws multiprocessing under the bus and produces a lot of bugs. I’ve also encountered other issues but currently have trouble consistently replicating it.

That seems like a bug, can you open a github issue? Thanks.
