AsyncPredictor

Make async predictions against SageMaker endpoints with Python objects

class sagemaker.predictor_async.AsyncPredictor(predictor, name=None)

Bases: object

Make async prediction requests to an Amazon SageMaker endpoint.

Initialize an AsyncPredictor.

Parameters

predictor (sagemaker.predictor.Predictor) – General Predictor object has useful methods and variables. AsyncPredictor stands on top of it with capability for async inference.

predict(data=None, input_path=None, initial_args=None, inference_id=None, waiter_config=<sagemaker.async_inference.waiter_config.WaiterConfig object>)

Wait and return the Async Inference result from the specified endpoint.

Parameters
  • data (object) – Input data for which you want the model to provide inference. If a serializer was specified in the encapsulated Predictor object, the result of the serializer is sent as input data. Otherwise the data must be sequence of bytes, and the predict method then sends the bytes in the request body as is.

  • input_path (str) – Amazon S3 URI contains input data for which you want the model to provide async inference. (Default: None)

  • initial_args (dict[str,str]) – Optional. Default arguments for boto3 invoke_endpoint_async call. (Default: None).

  • inference_id (str) – If you provide a value, it is added to the captured data when you enable data capture on the endpoint (Default: None).

  • waiter_config (sagemaker.async_inference.waiter_config.WaiterConfig) – Configuration for the waiter. (Default: {“Delay”: 15 seconds, “MaxAttempts”: 60}

Raises

ValueError – If both input data and input Amazon S3 path are not provided

Returns

Inference for the given input. If a deserializer was specified when creating

the Predictor, the result of the deserializer is returned. Otherwise the response returns the sequence of bytes as is.

Return type

object

predict_async(data=None, input_path=None, initial_args=None, inference_id=None)

Return the Async Inference ouput Amazon S3 path from the specified endpoint.

Parameters
  • data (object) – Input data for which you want the model to provide inference. If a serializer was specified in the encapsulated Predictor object, the result of the serializer is sent as input data. Otherwise the data must be sequence of bytes, and the predict method then upload the data to the input_s3_path. If input_s3_path is None, upload the data to

  • input_path (str) – Amazon S3 URI contains input data for which you want the model to provide async inference. (Default: None)

  • initial_args (dict[str,str]) – Optional. Default arguments for boto3 invoke_endpoint_async call. (Default: None).

  • inference_id (str) – If you provide a value, it is added to the captured data when you enable data capture on the endpoint (Default: None).

Raises

ValueError – If both input data and input Amazon S3 path are not provided

Returns

Inference response for the given input. It provides method to check the result in the Amazon S3 output path.

Return type

AsyncInferenceResponse

update_endpoint(initial_instance_count=None, instance_type=None, accelerator_type=None, model_name=None, tags=None, kms_key=None, data_capture_config_dict=None, wait=True)

Update the existing endpoint with the provided attributes.

This creates a new EndpointConfig in the process. If initial_instance_count, instance_type, accelerator_type, or model_name is specified, then a new ProductionVariant configuration is created; values from the existing configuration are not preserved if any of those parameters are specified.

Parameters
  • initial_instance_count (int) – The initial number of instances to run in the endpoint. This is required if instance_type, accelerator_type, or model_name is specified. Otherwise, the values from the existing endpoint configuration’s ProductionVariants are used.

  • instance_type (str) – The EC2 instance type to deploy the endpoint to. This is required if initial_instance_count or accelerator_type is specified. Otherwise, the values from the existing endpoint configuration’s ProductionVariants are used.

  • accelerator_type (str) – The type of Elastic Inference accelerator to attach to the endpoint, e.g. “ml.eia1.medium”. If not specified, and initial_instance_count, instance_type, and model_name are also None, the values from the existing endpoint configuration’s ProductionVariants are used. Otherwise, no Elastic Inference accelerator is attached to the endpoint.

  • model_name (str) – The name of the model to be associated with the endpoint. This is required if initial_instance_count, instance_type, or accelerator_type is specified and if there is more than one model associated with the endpoint. Otherwise, the existing model for the endpoint is used.

  • tags (list[dict[str, str]]) – The list of tags to add to the endpoint config. If not specified, the tags of the existing endpoint configuration are used. If any of the existing tags are reserved AWS ones (i.e. begin with “aws”), they are not carried over to the new endpoint configuration.

  • kms_key (str) – The KMS key that is used to encrypt the data on the storage volume attached to the instance hosting the endpoint If not specified, the KMS key of the existing endpoint configuration is used.

  • data_capture_config_dict (dict) – The endpoint data capture configuration for use with Amazon SageMaker Model Monitoring. If not specified, the data capture configuration of the existing endpoint configuration is used.

  • wait (bool) – Wait for updating to finish

delete_endpoint(delete_endpoint_config=True)

Delete the Amazon SageMaker endpoint backing this async predictor.

This also delete the endpoint configuration attached to it if delete_endpoint_config is True.

Parameters

delete_endpoint_config (bool, optional) – Flag to indicate whether to delete endpoint configuration together with endpoint. Defaults to True. If True, both endpoint and endpoint configuration will be deleted. If False, only endpoint will be deleted.

delete_model()

Deletes the Amazon SageMaker models backing this predictor.

enable_data_capture()

Enables data capture by updating DataCaptureConfig.

This function updates the DataCaptureConfig for the Predictor’s associated Amazon SageMaker Endpoint to enable data capture. For a more customized experience, refer to update_data_capture_config, instead.

disable_data_capture()

Disables data capture by updating DataCaptureConfig.

This function updates the DataCaptureConfig for the Predictor’s associated Amazon SageMaker Endpoint to disable data capture. For a more customized experience, refer to update_data_capture_config, instead.

update_data_capture_config(data_capture_config)

Updates the DataCaptureConfig for the Predictor’s associated Amazon SageMaker Endpoint.

Update is done using the provided DataCaptureConfig.

Parameters

data_capture_config (sagemaker.model_monitor.DataCaptureConfig) – The DataCaptureConfig to update the predictor’s endpoint to use.

list_monitors()

Generates ModelMonitor objects (or DefaultModelMonitors).

Objects are generated based on the schedule(s) associated with the endpoint that this predictor refers to.

Returns

A list of

ModelMonitor (or DefaultModelMonitor) objects.

Return type

[sagemaker.model_monitor.model_monitoring.ModelMonitor]

endpoint_context()

Retrieves the lineage context object representing the endpoint.

Examples

predictor = Predictor()
context = predictor.endpoint_context()
models = context.models()
Returns

The context for the endpoint.

Return type

ContextEndpoint
