Jiaming Yuan	80065d571e	[dask] Add DaskXGBRanker (#6576) ... * Initial support for distributed LTR using dask. * Support `qid` in libxgboost. * Refactor `predict` and `n_features_in_`, `best_[score/iteration/ntree_limit]` to avoid duplicated code. * Define `DaskXGBRanker`. The dask ranker doesn't support group structure, instead it uses query id and convert to group ptr internally.	2021-01-08 18:35:09 +08:00
