Perform an online explanation.

If deployed_model_id is specified, the corresponding DeployModel must have explanation_spec populated. If deployed_model_id is not specified, all DeployedModels must have explanation_spec populated.

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::PredictionService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::ExplainRequest.new

# Call the explain method.
result = client.explain request

# The returned object is of type Google::Cloud::AIPlatform::V1::ExplainResponse.
p result

Overloads:

  • #explain(request, options = nil) ⇒ ::Google::Cloud::AIPlatform::V1::ExplainResponse

    Pass arguments to explain via a request object, either of type ExplainRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AIPlatform::V1::ExplainRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #explain(endpoint: nil, instances: nil, parameters: nil, explanation_spec_override: nil, deployed_model_id: nil) ⇒ ::Google::Cloud::AIPlatform::V1::ExplainResponse

    Pass arguments to explain via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • endpoint (::String) (defaults to: nil) —

      Required. The name of the Endpoint requested to serve the explanation. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

    • instances (::Array<::Google::Protobuf::Value, ::Hash>) (defaults to: nil) —

      Required. The instances that are the input to the explanation call. A DeployedModel may have an upper limit on the number of instances it supports per request, and when it is exceeded the explanation call errors in case of AutoML Models, or, in case of customer created Models, the behaviour is as documented by that Model. The schema of any single instance may be specified via Endpoint's DeployedModels' [Model's][google.cloud.aiplatform.v1.DeployedModel.model] [PredictSchemata's][google.cloud.aiplatform.v1.Model.predict_schemata] instance_schema_uri.

    • parameters (::Google::Protobuf::Value, ::Hash) (defaults to: nil) —

      The parameters that govern the prediction. The schema of the parameters may be specified via Endpoint's DeployedModels' [Model's ][google.cloud.aiplatform.v1.DeployedModel.model] [PredictSchemata's][google.cloud.aiplatform.v1.Model.predict_schemata] parameters_schema_uri.

    • explanation_spec_override (::Google::Cloud::AIPlatform::V1::ExplanationSpecOverride, ::Hash) (defaults to: nil) —

      If specified, overrides the explanation_spec of the DeployedModel. Can be used for explaining prediction results with different configurations, such as:

      • Explaining top-5 predictions results as opposed to top-1;
      • Increasing path count or step count of the attribution methods to reduce approximate errors;
      • Using different baselines for explaining the prediction results.
    • deployed_model_id (::String) (defaults to: nil) —

      If specified, this ExplainRequest will be served by the chosen DeployedModel, overriding Endpoint.traffic_split.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

#raw_predict(request, options = nil) ⇒ ::Google::Api::HttpBody #raw_predict(endpoint: nil, http_body: nil) ⇒ ::Google::Api::HttpBody

Perform an online prediction with an arbitrary HTTP payload.

The response includes the following HTTP headers:

  • X-Vertex-AI-Endpoint-Id: ID of the Endpoint that served this prediction.

  • X-Vertex-AI-Deployed-Model-Id: ID of the Endpoint's DeployedModel that served this prediction.

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::PredictionService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::RawPredictRequest.new

# Call the raw_predict method.
result = client.raw_predict request

# The returned object is of type Google::Api::HttpBody.
p result

Overloads:

  • #raw_predict(request, options = nil) ⇒ ::Google::Api::HttpBody

    Pass arguments to raw_predict via a request object, either of type RawPredictRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AIPlatform::V1::RawPredictRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #raw_predict(endpoint: nil, http_body: nil) ⇒ ::Google::Api::HttpBody

    Pass arguments to raw_predict via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • endpoint (::String) (defaults to: nil) —

      Required. The name of the Endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

    • http_body (::Google::Api::HttpBody, ::Hash) (defaults to: nil) —

      The prediction input. Supports HTTP headers and arbitrary data payload.

      A DeployedModel may have an upper limit on the number of instances it supports per request. When this limit it is exceeded for an AutoML model, the RawPredict method returns an error. When this limit is exceeded for a custom-trained model, the behavior varies depending on the model.

      You can specify the schema for each instance in the predict_schemata.instance_schema_uri field when you create a Model. This schema applies when you deploy the Model as a DeployedModel to an Endpoint and use the RawPredict method.

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

#stream_raw_predict(request, options = nil) ⇒ ::Enumerable<::Google::Api::HttpBody> #stream_raw_predict(endpoint: nil, http_body: nil) ⇒ ::Enumerable<::Google::Api::HttpBody>

Perform a streaming online prediction with an arbitrary HTTP payload.

Examples:

Basic example

require "google/cloud/ai_platform/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::AIPlatform::V1::PredictionService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::AIPlatform::V1::StreamRawPredictRequest.new

# Call the stream_raw_predict method to start streaming.
output = client.stream_raw_predict request

# The returned object is a streamed enumerable yielding elements of type
# ::Google::Api::HttpBody
output.each do |current_response|
  p current_response
end

Overloads:

  • #stream_raw_predict(request, options = nil) ⇒ ::Enumerable<::Google::Api::HttpBody>

    Pass arguments to stream_raw_predict via a request object, either of type StreamRawPredictRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::AIPlatform::V1::StreamRawPredictRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries etc. Optional.

  • #stream_raw_predict(endpoint: nil, http_body: nil) ⇒ ::Enumerable<::Google::Api::HttpBody>

    Pass arguments to stream_raw_predict via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • endpoint (::String) (defaults to: nil) —

      Required. The name of the Endpoint requested to serve the prediction. Format: projects/{project}/locations/{location}/endpoints/{endpoint}

    • http_body (::Google::Api::HttpBody, ::Hash) (defaults to: nil) —

      The prediction input. Supports HTTP headers and arbitrary data payload.

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
