    algorithm based on XGBoost python library, and it can be used in PySpark Pipeline
    and PySpark ML meta algorithms like
    - :py:class:`~pyspark.ml.tuning.CrossValidator`/
    - :py:class:`~pyspark.ml.tuning.TrainValidationSplit`/
    - :py:class:`~pyspark.ml.classification.OneVsRest`

    SparkXGBRegressor automatically supports most of the parameters in
    :py:class:`xgboost.XGBRegressor` constructor and most of the parameters used in
    :py:meth:`xgboost.XGBRegressor.fit` and :py:meth:`xgboost.XGBRegressor.predict`
    method.

    To enable GPU support, set `device` to `cuda` or `gpu`.

    SparkXGBRegressor doesn't support setting `base_margin` explicitly as well, but
    support another param called `base_margin_col`. see doc below for more details.

    SparkXGBRegressor doesn't support `validate_features` and `output_margin` param.

    SparkXGBRegressor doesn't support setting `nthread` xgboost param, instead, the
    `nthread` param for each xgboost worker will be set equal to `spark.task.cpus`
    config value.


    Parameters

        fit method.
    weight_col:
        To specify the weight of the training and validation dataset, set
        :py:attr:`xgboost.spark.SparkXGBRegressor.weight_col` parameter instead of setting

        To specify the base margins of the training and validation
        dataset, set :py:attr:`xgboost.spark.SparkXGBRegressor.base_margin_col` parameter

    ranking algorithm based on XGBoost python library, and it can be used in
    PySpark Pipeline and PySpark ML meta algorithms like
    :py:class:`~pyspark.ml.tuning.CrossValidator`/
    :py:class:`~pyspark.ml.tuning.TrainValidationSplit`/
    :py:class:`~pyspark.ml.classification.OneVsRest`

    SparkXGBRanker automatically supports most of the parameters in
    :py:class:`xgboost.XGBRanker` constructor and most of the parameters used in
    :py:meth:`xgboost.XGBRanker.fit` and :py:meth:`xgboost.XGBRanker.predict` method.

    To enable GPU support, set `device` to `cuda` or `gpu`.

    SparkXGBRanker doesn't support setting `base_margin` explicitly as well, but support
    another param called `base_margin_col`. see doc below for more details.

    SparkXGBRanker doesn't support setting `output_margin`, but we can get output margin
    from the raw prediction column. See `raw_prediction_col` param doc below for more
    details.

    SparkXGBRanker doesn't support `validate_features` and `output_margin` param.

    SparkXGBRanker doesn't support setting `nthread` xgboost param, instead, the
    `nthread` param for each xgboost worker will be set equal to `spark.task.cpus`
    config value.


    Parameters
    ----------

    features_col:
        When the value is string, it requires the features column name to be vector type.
        When the value is a list of string, it requires all the feature columns to be numeric types.
    label_col:
        Label column name. Default to "label".
    prediction_col:
        Prediction column name. Default to "prediction"
    pred_contrib_col:
        Contribution prediction column name.
    validation_indicator_col:
        For params related to `xgboost.XGBRanker` training with
        evaluation dataset's supervision,
        set :py:attr:`xgboost.spark.SparkXGBRanker.validation_indicator_col`
        parameter instead of setting the `eval_set` parameter in :py:class:`xgboost.XGBRanker`
        fit method.
    weight_col:
        To specify the weight of the training and validation dataset, set
        :py:attr:`xgboost.spark.SparkXGBRanker.weight_col` parameter instead of setting
        `sample_weight` and `sample_weight_eval_set` parameter in :py:class:`xgboost.XGBRanker`
        fit method.
    base_margin_col:
        To specify the base margins of the training and validation
        dataset, set :py:attr:`xgboost.spark.SparkXGBRanker.base_margin_col` parameter
        instead of setting `base_margin` and `base_margin_eval_set` in the
        :py:class:`xgboost.XGBRanker` fit method.
    qid_col:
        Query id column name.
    num_workers:
        How many XGBoost workers to be used to train.
        Each XGBoost worker corresponds to one spark task.
    use_gpu:
        .. deprecated:: 2.0.0

        Use `device` instead.

    device:

        .. versionadded:: 2.0.0

        Device for XGBoost workers, available options are `cpu`, `cuda`, and `gpu`.

    force_repartition:
        Boolean value to specify if forcing the input dataset to be repartitioned
        before XGBoost training.
    repartition_random_shuffle:
        Boolean value to specify if randomly shuffling the dataset when repartitioning is required.
    enable_sparse_data_optim:
        Boolean value to specify if enabling sparse data optimization, if True,
        Xgboost DMatrix object will be constructed from sparse matrix instead of
        dense matrix.

    kwargs:
        A dictionary of xgboost parameters, please refer to
        https://xgboost.readthedocs.io/en/stable/parameter.html

    .. Note:: The Parameters chart above contains parameters that need special handling.
        For a full list of parameters, see entries with `Param(parent=...` below.

    .. Note:: This API is experimental.
