    Start a Google Cloud ML Engine prediction job.

    This operator is deprecated. Please use
    :class:`airflow.providers.google.cloud.operators.vertex_ai.batch_prediction.CreateBatchPredictionJobOperator`
    instead.

    .. seealso::
        For more information on how to use this operator, take a look at the guide:
        :ref:`howto/operator:MLEngineStartBatchPredictionJobOperator`

    NOTE: For model origin, users should consider exactly one from the
    three options below:

    1. Populate ``uri`` field only, which should be a GCS location that
       points to a tensorflow savedModel directory.
    2. Populate ``model_name`` field only, which refers to an existing
       model, and the default version of the model will be used.
    3. Populate both ``model_name`` and ``version_name`` fields, which
       refers to a specific version of a specific model.

    In options 2 and 3, both model and version name should contain the
    minimal identifier. For instance, call::

        MLEngineStartBatchPredictionJobOperator(
            ...,
            model_name='my_model',
            version_name='my_version',
            ...)

    if the desired model version is
    ``projects/my_project/models/my_model/versions/my_version``.

    See https://cloud.google.com/ml-engine/reference/rest/v1/projects.jobs
    for further documentation on the parameters.

    :param job_id: A unique id for the prediction job on Google Cloud
        ML Engine. (templated)
    :param data_format: The format of the input data.
        It will default to 'DATA_FORMAT_UNSPECIFIED' if is not provided
        or is not one of ["TEXT", "TF_RECORD", "TF_RECORD_GZIP"].
    :param input_paths: A list of GCS paths of input data for batch
        prediction. Accepting wildcard operator ``*``, but only at the end. (templated)
    :param output_path: The GCS path where the prediction results are
        written to. (templated)
    :param region: The Google Compute Engine region to run the
        prediction job in. (templated)
    :param model_name: The Google Cloud ML Engine model to use for prediction.
        If version_name is not provided, the default version of this
        model will be used.
        Should not be None if version_name is provided.
        Should be None if uri is provided. (templated)
    :param version_name: The Google Cloud ML Engine model version to use for
        prediction.
        Should be None if uri is provided. (templated)
    :param uri: The GCS path of the saved model to use for prediction.
        Should be None if model_name is provided.
        It should be a GCS path pointing to a tensorflow SavedModel. (templated)
    :param max_worker_count: The maximum number of workers to be used
        for parallel processing. Defaults to 10 if not specified. Should be a
        string representing the worker count ("10" instead of 10, "50" instead
        of 50, etc.)
    :param runtime_version: The Google Cloud ML Engine runtime version to use
        for batch prediction.
    :param signature_name: The name of the signature defined in the SavedModel
        to use for this job.
    :param project_id: The Google Cloud project name where the prediction job is submitted.
        If set to None or missing, the default project_id from the Google Cloud connection is used.
        (templated)
    :param gcp_conn_id: The connection ID used for connection to Google
        Cloud Platform.
    :param labels: a dictionary containing labels for the job; passed to BigQuery
    :param impersonation_chain: Optional service account to impersonate using short-term
        credentials, or chained list of accounts required to get the access_token
        of the last account in the list, which will be impersonated in the request.
        If set as a string, the account must grant the originating account
        the Service Account Token Creator IAM role.
        If set as a sequence, the identities from the list must grant
        Service Account Token Creator IAM role to the directly preceding identity, with first

    :param job_id: A unique templated id for the submitted Google MLEngine
        training job. (templated)
    :param region: The Google Compute Engine region to run the MLEngine training
        job in (templated).
    :param package_uris: A list of Python package locations for the training
        job, which should include the main training program and any additional
        dependencies. This is mutually exclusive with a custom image specified
        via master_config. (templated)
    :param training_python_module: The name of the Python module to run within
        the training job after installing the packages. This is mutually
        exclusive with a custom image specified via master_config. (templated)
    :param training_args: A list of command-line arguments to pass to the
        training program. (templated)
    :param scale_tier: Resource tier for MLEngine training job. (templated)
    :param master_type: The type of virtual machine to use for the master
        worker. It must be set whenever scale_tier is CUSTOM. (templated)
    :param master_config: The configuration for the master worker. If this is
        provided, master_type must be set as well. If a custom image is
        specified, this is mutually exclusive with package_uris and
        training_python_module. (templated)
    :param runtime_version: The Google Cloud ML runtime version to use for
        training. (templated)
    :param python_version: The version of Python used in training. (templated)
    :param job_dir: A Google Cloud Storage path in which to store training
        outputs and other data needed for training. (templated)
    :param service_account: Optional service account to use when running the training application.
        (templated)
        The specified service account must have the `iam.serviceAccounts.actAs` role. The
        Google-managed Cloud ML Engine service account must have the `iam.serviceAccountAdmin` role
        for the specified service account.
        If set to None or missing, the Google-managed Cloud ML Engine service account will be used.
    :param project_id: The Google Cloud project name within which MLEngine training job should run.
    :param gcp_conn_id: The connection ID to use when fetching connection info.
    :param mode: Can be one of 'DRY_RUN'/'CLOUD'. In 'DRY_RUN' mode, no real
        training job will be launched, but the MLEngine training job request
        will be printed out. In 'CLOUD' mode, a real MLEngine training job
        creation request will be issued.
    :param labels: a dictionary containing labels for the job; passed to BigQuery
    :param hyperparameters: Optional HyperparameterSpec dictionary for hyperparameter tuning.
        For further reference, check:
        https://cloud.google.com/ai-platform/training/docs/reference/rest/v1/projects.jobs#HyperparameterSpec
    :param impersonation_chain: Optional service account to impersonate using short-term
        credentials, or chained list of accounts required to get the access_token
        of the last account in the list, which will be impersonated in the request.
        If set as a string, the account must grant the originating account
        the Service Account Token Creator IAM role.
        If set as a sequence, the identities from the list must grant
        Service Account Token Creator IAM role to the directly preceding identity, with first
        account from the list granting this role to the originating account (templated).
