   .. py:method:: create_training_job(self, config, wait_for_completion = True, print_log = True, check_interval = 30, max_ingestion_time = None)

      Starts a model training job. After training completes, Amazon SageMaker saves
      the resulting model artifacts to an Amazon S3 location that you specify.

      :param config: the config for training
      :param wait_for_completion: if the program should keep running until job finishes
      :param check_interval: the time interval in seconds which the operator
          will check the status of any SageMaker job
      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
      :return: A response to training job creation


   .. py:method:: create_tuning_job(self, config, wait_for_completion = True, check_interval = 30, max_ingestion_time = None)

      Starts a hyperparameter tuning job. A hyperparameter tuning job finds the
      best version of a model by running many training jobs on your dataset using
      the algorithm you choose and values for hyperparameters within ranges that
      you specify. It then chooses the hyperparameter values that result in a model
      that performs the best, as measured by an objective metric that you choose.

      :param config: the config for tuning
      :param wait_for_completion: if the program should keep running until job finishes
      :param check_interval: the time interval in seconds which the operator
          will check the status of any SageMaker job
      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
      :return: A response to tuning job creation


   .. py:method:: create_transform_job(self, config, wait_for_completion = True, check_interval = 30, max_ingestion_time = None)

      Starts a transform job. A transform job uses a trained model to get inferences
      on a dataset and saves these results to an Amazon S3 location that you specify.

      :param config: the config for transform job
      :param wait_for_completion: if the program should keep running until job finishes
      :param check_interval: the time interval in seconds which the operator
          will check the status of any SageMaker job
      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
      :return: A response to transform job creation


   .. py:method:: create_processing_job(self, config, wait_for_completion = True, check_interval = 30, max_ingestion_time = None)

      Use Amazon SageMaker Processing to analyze data and evaluate machine learning
      models on Amazon SageMaker. With Processing, you can use a simplified, managed
      experience on SageMaker to run your data processing workloads, such as feature
      engineering, data validation, model evaluation, and model interpretation.

      :param config: the config for processing job
      :param wait_for_completion: if the program should keep running until job finishes
      :param check_interval: the time interval in seconds which the operator
          will check the status of any SageMaker job
      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
      :return: A response to transform job creation


   .. py:method:: create_model(self, config)

      Creates a model in Amazon SageMaker. In the request, you name the model and
      describe a primary container. For the primary container, you specify the Docker
      image that contains inference code, artifacts (from prior training), and a custom
      environment map that the inference code uses when you deploy the model for predictions.

      :param config: the config for model
      :return: A response to model creation


   .. py:method:: create_endpoint_config(self, config)

      Creates an endpoint configuration that Amazon SageMaker hosting
      services uses to deploy models. In the configuration, you identify
      one or more models, created using the CreateModel API, to deploy and
      the resources that you want Amazon SageMaker to provision.

      .. seealso::
           :class:`~airflow.providers.amazon.aws.hooks.sagemaker.SageMakerHook.create_model`
           :class:`~airflow.providers.amazon.aws.hooks.sagemaker.SageMakerHook.create_endpoint`

      :param config: the config for endpoint-config
      :return: A response to endpoint config creation


   .. py:method:: create_endpoint(self, config, wait_for_completion = True, check_interval = 30, max_ingestion_time = None)

      When you create a serverless endpoint, SageMaker provisions and manages
      the compute resources for you. Then, you can make inference requests to
      the endpoint and receive model predictions in response. SageMaker scales
      the compute resources up and down as needed to handle your request traffic.

      Requires an Endpoint Config.

      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
      :return: A response to endpoint creation


   .. py:method:: update_endpoint(self, config, wait_for_completion = True, check_interval = 30, max_ingestion_time = None)

      Deploys the new EndpointConfig specified in the request, switches to using
      newly created endpoint, and then deletes resources provisioned for the
      endpoint using the previous EndpointConfig (there is no availability loss).

      :param config: the config for endpoint
      :param wait_for_completion: if the program should keep running until job finishes
      :param check_interval: the time interval in seconds which the operator
          will check the status of any SageMaker job
      :param max_ingestion_time: the maximum ingestion time in seconds. Any
          SageMaker jobs that run longer than this will fail. Setting this to
          None implies no timeout for any SageMaker job.
