    """
    A wrapper around :func:`train_model` which loads the params from a file.

    Parameters
    ----------
    parameter_filename : ``str``
        A json parameter file specifying an AllenNLP experiment.
    serialization_dir : ``str``
        The directory in which to save results and logs. We just pass this along to
        :func:`train_model`.
    overrides : ``str``
        A JSON string that we will use to override values in the input parameter file.
    file_friendly_logging : ``bool``, optional (default=False)
        If ``True``, we make our output more friendly to saved model files.  We just pass this
        along to :func:`train_model`.
    recover : ``bool`, optional (default=False)
        If ``True``, we will try to recover a training run from an existing serialization
        directory.  This is only intended for use when something actually crashed during the middle
        of a run.  For continuing training a model on new data, see the ``fine-tune`` command.
    force : ``bool``, optional (default=False)
        If ``True``, we will overwrite the serialization directory if it already exists.
    cache_directory : ``str``, optional
        For caching data pre-processing.  See :func:`allennlp.training.util.datasets_from_params`.
    cache_prefix : ``str``, optional
        For caching data pre-processing.  See :func:`allennlp.training.util.datasets_from_params`.
