        Args:
            booster: The LightGBM model to store in the checkpoint.
            preprocessor: A fitted preprocessor to be applied before inference.
            path: The path to the directory where the checkpoint file will be saved.
                This should start as an empty directory, since the *entire*
                directory will be treated as the checkpoint when reported.
                By default, a temporary directory will be created.

        Returns:
            An :py:class:`LightGBMCheckpoint` containing the specified ``Estimator``.

        Examples:
            .. testcode::

                import lightgbm
                import numpy as np
                from ray.train.lightgbm import LightGBMCheckpoint

                train_X = np.array([[1, 2], [3, 4]])
                train_y = np.array([0, 1])

                model = lightgbm.LGBMClassifier().fit(train_X, train_y)
                checkpoint = LightGBMCheckpoint.from_model(model.booster_)
