@yinxusen Thanks very much for working on this patch. Iâve spent quite
a bit of time trying to figure out how to simplify it, but given the very
little time left before the code freeze, I think it will be best if we exclude
persistence for model tuning in Python for this release. To keep the current
approach, we would need to clearly document its limitations, and the current
approach is too ad-hoc for me to be confident in writing that documentation. I
think we can design a cleaner approach for the next release, including some
general simplifications to the Python wrapper API.
Iâll work on reverting the current save/load for python tuning and CC you
on the PRs.
Could you please close this issue? Please keep the branch since the
integration test will be useful in the future. Also, could you please send a
small patch with the Scala fixes which are in your PR?
Thanks a lot!
