can't we add it to the baseclass so we don't need to hasattr check it?

We don't need it, I just added the hasattr so that pm.sample() does not throw.

I see there's a set_rng... could this be passed into setup? I haven't checked when/where is it called from

I think set_rng is called per chain. If we move set_rng to setup, then the rng would be shared across chains, and vice versa if we move setup to set_rng then it would be called for each chain repeatedly. That would not be an issue in the current implementation of BART because we can check if setup has already been called. Then the method should be renamed to something like setup_chain

Yeah setup_chain sounds good enough, and we combine both sources of info
…d tune as well as chain rng

Description
I added a function to
pm.sample(...)that passes the number of draws to the step methods if they have thesetupattribute. With this setup method, we can pre-allocate a vector to storeTreeBatchfor each sampling draw inbartrs.Related Issue
