(
        self, study: Study, trial: FrozenTrial, search_space: Dict[str, BaseDistribution]
    )
Sample parameters in a given search space.

        This method is called once at the beginning of each trial, i.e., right before the
        evaluation of the objective function. This method is suitable for sampling algorithms
        that use relationship between parameters such as Gaussian Process and CMA-ES.

        .. note::
                The failed trials are ignored by any build-in samplers when they sample new
                parameters. Thus, failed trials are regarded as deleted in the samplers'
                perspective.

        Args:
            study:
                Target study object.
            trial:
                Target trial object.
                Take a copy before modifying this object.
            search_space:
                The search space returned by
                :func:`~optuna.samplers.BaseSampler.infer_relative_search_space`.

        Returns:
            A dictionary containing the parameter names and the values.
