@detrin not for your training data, i.e. not for polars data frames. Polars uses column-wise storage, i.e. each of your columns is represented by a contiguous chunk of memory (but...

See @jameslamb's comment above for LightGBM's "API": > CSV, TSV, and LibSVM files You could e.g. write your data to CSV. Obviously, this introduces some performance hit.

FYI (not sure if this is common knowledge yet): when developing on LightGBM on Apple Silicon, I never turned off OpenMP but used `gcc` instead of `clang` for compilation (for...

This is odd, I just ran into a similar issue with the `postgres` dialect. The following causes the same issue as above when calling `fix` (although there is nothing to...

Sorry @jameslamb, I saw your comment only now! Unfortunately, I also can't restart Azure jobs, my login continues to fail 🙄

@jameslamb I just thought again about adding documentation about how to pass `polars` data to LightGBM. Where do you think is the most appropriate place for this? I wouldn't want...

This is exciting! From a user's POV: what can be expected from this design proposal? Does it lay the groundwork for implementation s.t. there will be an experimental implementation available...
