The currently active AWS account must have correct permissions set up. This function creates a SageMaker endpoint. For more information about the input data formats accepted by this endpoint, see the :ref:`MLflow deployment tools documentation <sagemaker_deployment>`. :param app_name: Name of the deployed application. :param model_uri: The location, in URI format, of the MLflow model to deploy to SageMaker. For example: - ``/Users/me/path/to/local/model`` - ``relative/path/to/local/model`` - ``s3://my_bucket/path/to/model`` - ``runs:/<mlflow_run_id>/run-relative/path/to/model`` - ``models:/<model_name>/<model_version>`` - ``models:/<model_name>/<stage>`` For more information about supported URI schemes, see `Referencing Artifacts <https://www.mlflow.org/docs/latest/concepts.html# artifact-locations>`_. :param execution_role_arn: The name of an IAM role granting the SageMaker service permissions to access the specified Docker image and S3 bucket containing MLflow model artifacts. If unspecified, the currently-assumed role will be used. This execution role is passed to the SageMaker service when creating a SageMaker model from the specified MLflow model. It is passed as the ``ExecutionRoleArn`` parameter of the `SageMaker CreateModel API call <https://docs.aws.amazon.com/sagemaker/latest/ dg/API_CreateModel.html>`_. This role is *not* assumed for any other call. For more information about SageMaker execution roles for model creation, see https://docs.aws.amazon.com/sagemaker/latest/dg/sagemaker-roles.html. :param bucket: S3 bucket where model artifacts will be stored. Defaults to a SageMaker-compatible bucket name. :param image_url: URL of the ECR-hosted Docker image the model should be deployed into, produced by ``mlflow sagemaker build-and-push-container``. This parameter can also be specified by the environment variable ``MLFLOW_SAGEMAKER_DEPLOY_IMG_URL``. :param region_name: Name of the AWS region to which to deploy the application. :param mode: The mode in which to deploy the application. Must be one of the following: ``mlflow.sagemaker.DEPLOYMENT_MODE_CREATE`` Create an application with the specified name and model. This fails if an application of the same name already exists. ``mlflow.sagemaker.DEPLOYMENT_MODE_REPLACE`` If an application of the specified name exists, its model(s) is replaced with the specified model. If no such application exists, it is created with the specified name and model. ``mlflow.sagemaker.DEPLOYMENT_MODE_ADD`` Add the specified model to a pre-existing application with the specified name, if one exists. If the application does not exist, a new application is created with the specified name and model. NOTE: If the application **already exists**, the specified model is added to the application's corresponding SageMaker endpoint with an initial weight of zero (0). To route traffic to the model, update the application's associated endpoint configuration using either the AWS console or the ``UpdateEndpointWeightsAndCapacities`` function defined in https://docs.aws.amazon.com/sagemaker/latest/dg/API_UpdateEndpointWeightsAndCapacities.html. :param archive: If ``True``, any pre-existing SageMaker application resources that become inactive (i.e. as a result of deploying in ``mlflow.sagemaker.DEPLOYMENT_MODE_REPLACE`` mode) are preserved. These resources may include unused SageMaker models and endpoint configurations that were associated with a prior version of the application endpoint. If ``False``, these resources are deleted. In order to use ``archive=False``, ``deploy()`` must be executed synchronously with ``synchronous=True``. :param instance_type: The type of SageMaker ML instance on which to deploy the model. For a list of supported instance types, see https://aws.amazon.com/sagemaker/pricing/instance-types/. :param instance_count: The number of SageMaker ML instances on which to deploy the model. :param vpc_config: A dictionary specifying the VPC configuration to use when creating the new SageMaker model associated with this application. The acceptable values for this parameter are identical to those of the ``VpcConfig`` parameter in the `SageMaker boto3 client's create_model method <https://boto3.readthedocs.io/en/latest/reference/services/sagemaker.html #SageMaker.Client.create_model>`_. For more information, see https://docs.aws.amazon.com/sagemaker/latest/dg/API_VpcConfig.html. .. code-block:: python :caption: Example import mlflow.sagemaker as mfs vpc_config = { 'SecurityGroupIds': [ 'sg-123456abc', ], 'Subnets': [ 'subnet-123456abc', ] } mfs.deploy(..., vpc_config=vpc_config) :param flavor: The name of the flavor of the model to use for deployment. Must be either ``None`` or one of mlflow.sagemaker.SUPPORTED_DEPLOYMENT_FLAVORS. If ``None``, a flavor is automatically selected from the model's available flavors. If the specified flavor is not present or not supported for deployment, an exception will be thrown. :param synchronous: If ``True``, this function will block until the deployment process succeeds or encounters an irrecoverable failure. If ``False``, this function will return immediately after starting the deployment process. It will not wait for the deployment process to complete; in this case, the caller is responsible for monitoring the health and status of the pending deployment via native SageMaker APIs or the AWS console. :param timeout_seconds: If ``synchronous`` is ``True``, the deployment process will return after the specified number of seconds if no definitive result (success or failure) is achieved. Once the function returns, the caller is responsible for monitoring the health and status of the pending deployment using native SageMaker APIs or the AWS console. If ``synchronous`` is ``False``, this parameter is ignored.
