Instance Method Details

#invoke_endpoint(params = {}) ⇒ Types::InvokeEndpointOutput

After you deploy a model into production using Amazon SageMaker hosting services, your client applications use this API to get inferences from the model hosted at the specified endpoint.

For an overview of Amazon SageMaker, see How It Works.

Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.

Calls to InvokeEndpoint are authenticated by using Amazon Web Services Signature Version 4. For information, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 API Reference.

A customer's model containers must respond to requests within 60 seconds. The model itself can have a maximum processing time of 60 seconds before responding to invocations. If your model is going to take 50-60 seconds of processing time, the SDK socket timeout should be set to be 70 seconds.

Endpoints are scoped to an individual account, and are not public. The URL does not contain the account ID, but Amazon SageMaker determines the account ID from the authentication token that is supplied by the caller.

Examples:

  endpoint_name: "EndpointName", # required
  body: "data", # required
  content_type: "Header",
  accept: "Header",
  custom_attributes: "CustomAttributesHeader",
  target_model: "TargetModelHeader",
  target_variant: "TargetVariantHeader",
  target_container_hostname: "TargetContainerHostnameHeader",
  inference_id: "InferenceId",
  enable_explanations: "EnableExplanationsHeader",
})

Response structure

resp.body #=> String
resp.content_type #=> String
resp.invoked_production_variant #=> String
resp.custom_attributes #=> String

Parameters:

• params (Hash) (defaults to: {}) —

  ({})

Options Hash (params):

• :endpoint_name (required, String) —

  The name of the endpoint that you specified when you created the endpoint using the CreateEndpoint API.

• :body (required, String, StringIO, File) —

  Provides input data, in the format specified in the ContentType request header. Amazon SageMaker passes all of the data in the body to the model.

  For information about the format of the request body, see Common Data Formats-Inference.

• :content_type (String) —

  The MIME type of the input data in the request body.

• :accept (String) —

  The desired MIME type of the inference response from the model container.

• :custom_attributes (String) —

  Provides additional information about a request for an inference submitted to a model hosted at an Amazon SageMaker endpoint. The information is an opaque value that is forwarded verbatim. You could use this value, for example, to provide an ID that you can use to track a request or to provide other metadata that a service endpoint was programmed to process. The value must consist of no more than 1024 visible US-ASCII characters as specified in Section 3.3.6. Field Value Components of the Hypertext Transfer Protocol (HTTP/1.1).

  The code in your model is responsible for setting or updating any custom attributes in the response. If your code does not set this value in the response, an empty value is returned. For example, if a custom attribute represents the trace ID, your model can prepend the custom attribute with Trace ID: in your post-processing function.

  This feature is currently supported in the Amazon Web Services SDKs but not in the Amazon SageMaker Python SDK.

• :target_model (String) —

  The model to request for inference when invoking a multi-model endpoint.

• :target_variant (String) —

  Specify the production variant to send the inference request to when invoking an endpoint that is running two or more variants. Note that this parameter overrides the default behavior for the endpoint, which is to distribute the invocation traffic based on the variant weights.

  For information about how to use variant targeting to perform a/b testing, see Test models in production

• :target_container_hostname (String) —

  If the endpoint hosts multiple containers and is configured to use direct invocation, this parameter specifies the host name of the container to invoke.

• :inference_id (String) —

  If you provide a value, it is added to the captured data when you enable data capture on the endpoint. For information about data capture, see Capture Data.

• :enable_explanations (String) —

  An optional JMESPath expression used to override the EnableExplanations parameter of the ClarifyExplainerConfig API. See the EnableExplanations section in the developer guide for more information.

Returns:

• (Types::InvokeEndpointOutput) —

  Returns a response object which responds to the following methods:

  • #body => String
  • #content_type => String
  • #invoked_production_variant => String
  • #custom_attributes => String

def invoke_endpoint(params = {}, options = {})
  req = build_request(:invoke_endpoint, params)
  req.send_request(options)
end

#invoke_endpoint_async(params = {}) ⇒ Types::InvokeEndpointAsyncOutput

After you deploy a model into production using Amazon SageMaker hosting services, your client applications use this API to get inferences from the model hosted at the specified endpoint in an asynchronous manner.

Inference requests sent to this API are enqueued for asynchronous processing. The processing of the inference request may or may not complete before you receive a response from this API. The response from this API will not contain the result of the inference request but contain information about where you can locate it.

Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.

Calls to InvokeEndpointAsync are authenticated by using Amazon Web Services Signature Version 4. For information, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 API Reference.

Examples:

Request syntax with placeholder values

resp = client.invoke_endpoint_async({
  endpoint_name: "EndpointName", # required
  content_type: "Header",
  accept: "Header",
  custom_attributes: "CustomAttributesHeader",

end

#invoke_endpoint_with_response_stream(params = {}) ⇒ Types::InvokeEndpointWithResponseStreamOutput

Invokes a model at the specified endpoint to return the inference response as a stream. The inference stream provides the response payload incrementally as a series of parts. Before you can get an inference stream, you must have access to a model that's deployed using Amazon SageMaker hosting services, and the container for that model must support inference streaming.

For more information that can help you use this API, see the following sections in the Amazon SageMaker Developer Guide:

• For information about how to add streaming support to a model, see How Containers Serve Requests.

• For information about how to process the streaming response, see Invoke real-time endpoints.

Amazon SageMaker strips all POST headers except those supported by the API. Amazon SageMaker might add additional headers. You should not rely on the behavior of headers outside those enumerated in the request syntax.

Calls to InvokeEndpointWithResponseStream are authenticated by using Amazon Web Services Signature Version 4. For information, see Authenticating Requests (Amazon Web Services Signature Version 4) in the Amazon S3 API Reference.

Examples:

EventStream Operation Example

You can process event once it arrives immediately, or wait until
full response complete and iterate through eventstream enumerator.

To interact with event immediately, you need to register #invoke_endpoint_with_response_stream
with callbacks, callbacks can be register for specifc events or for all events,
callback for errors in the event stream is also available for register.

Callbacks can be passed in by `:event_stream_handler` option or within block
statement attached to #invoke_endpoint_with_response_stream call directly. Hybrid pattern of both
is also supported.

`:event_stream_handler` option takes in either Proc object or
Aws::SageMakerRuntime::EventStreams::ResponseStream object.

Usage pattern a): callbacks with a block attached to #invoke_endpoint_with_response_stream
  Example for registering callbacks for all event types and error event

  client.invoke_endpoint_with_response_stream( # params input# ) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end

    stream.on_event do |event|
      # process all events arrive
      puts event.event_type
      ...
    end

  end

Usage pattern b): pass in `:event_stream_handler` for #invoke_endpoint_with_response_stream

  1) create a Aws::SageMakerRuntime::EventStreams::ResponseStream object
  Example for registering callbacks with specific events

    handler = Aws::SageMakerRuntime::EventStreams::ResponseStream.new
    handler.on_payload_part_event do |event|
      event # => Aws::SageMakerRuntime::Types::PayloadPart
    end
    handler.on_model_stream_error_event do |event|
      event # => Aws::SageMakerRuntime::Types::ModelStreamError
    end
    handler.on_internal_stream_failure_event do |event|
      event # => Aws::SageMakerRuntime::Types::InternalStreamFailure
    end

  client.invoke_endpoint_with_response_stream( # params input #, event_stream_handler: handler)

  2) use a Ruby Proc object
  Example for registering callbacks with specific events

  handler = Proc.new do |stream|
    stream.on_payload_part_event do |event|
      event # => Aws::SageMakerRuntime::Types::PayloadPart
    end
    stream.on_model_stream_error_event do |event|
      event # => Aws::SageMakerRuntime::Types::ModelStreamError
    end
    stream.on_internal_stream_failure_event do |event|
      event # => Aws::SageMakerRuntime::Types::InternalStreamFailure
    end
  end

  client.invoke_endpoint_with_response_stream( # params input #, event_stream_handler: handler)

Usage pattern c): hybird pattern of a) and b)

    handler = Aws::SageMakerRuntime::EventStreams::ResponseStream.new
    handler.on_payload_part_event do |event|
      event # => Aws::SageMakerRuntime::Types::PayloadPart
    end
    handler.on_model_stream_error_event do |event|
      event # => Aws::SageMakerRuntime::Types::ModelStreamError
    end
    handler.on_internal_stream_failure_event do |event|
      event # => Aws::SageMakerRuntime::Types::InternalStreamFailure
    end

  client.invoke_endpoint_with_response_stream( # params input #, event_stream_handler: handler) do |stream|
    stream.on_error_event do |event|
      # catch unmodeled error event in the stream
      raise event
      # => Aws::Errors::EventError
      # event.event_type => :error
      # event.error_code => String
      # event.error_message => String
    end
  end

Besides above usage patterns for process events when they arrive immediately, you can also
iterate through events after response complete.

Events are available at resp.body # => Enumerator

  The code in your model is responsible for setting or updating any custom attributes in the response. If your code does not set this value in the response, an empty value is returned. For example, if a custom attribute represents the trace ID, your model can prepend the custom attribute with Trace ID: in your post-processing function.

  This feature is currently supported in the Amazon Web Services SDKs but not in the Amazon SageMaker Python SDK.

• :target_variant (String) —

  Specify the production variant to send the inference request to when invoking an endpoint that is running two or more variants. Note that this parameter overrides the default behavior for the endpoint, which is to distribute the invocation traffic based on the variant weights.

  For information about how to use variant targeting to perform a/b testing, see Test models in production

• :target_container_hostname (String) —

  If the endpoint hosts multiple containers and is configured to use direct invocation, this parameter specifies the host name of the container to invoke.

• :inference_id (String) —

  An identifier that you assign to your request.

Yields:

• (event_stream_handler)

Returns:

• (Types::InvokeEndpointWithResponseStreamOutput) —

  Returns a response object which responds to the following methods:

  • #body => Types::ResponseStream
  • #content_type => String
  • #invoked_production_variant => String
  • #custom_attributes => String
