Methods
.configure
def self.configure() { |config| ... } -> Client::Configuration
Configure the PredictionService Client class.
See Configuration for a description of the configuration fields.
- (config) — Configure the Client client.
- config (Client::Configuration)
# Modify the configuration for all PredictionService clients ::Google::Cloud::AIPlatform::V1::PredictionService::Client.configure do |config| config.timeout = 10.0 end
#configure
def configure() { |config| ... } -> Client::Configuration
Configure the PredictionService Client instance.
The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.
See Configuration for a description of the configuration fields.
- (config) — Configure the Client client.
- config (Client::Configuration)
#explain
def explain(request, options = nil) -> ::Google::Cloud::AIPlatform::V1::ExplainResponse
def explain(endpoint: nil, instances: nil, parameters: nil, explanation_spec_override: nil, deployed_model_id: nil) -> ::Google::Cloud::AIPlatform::V1::ExplainResponse
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. Only deployed AutoML tabular Models have explanation_spec.
def explain(request, options = nil) -> ::Google::Cloud::AIPlatform::V1::ExplainResponse
explain
via a request object, either of type
ExplainRequest or an equivalent Hash.
- 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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.
def explain(endpoint: nil, instances: nil, parameters: nil, explanation_spec_override: nil, deployed_model_id: nil) -> ::Google::Cloud::AIPlatform::V1::ExplainResponse
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).
-
endpoint (::String) — Required. The name of the Endpoint requested to serve the explanation.
Format:
projects/{project}/locations/{location}/endpoints/{endpoint}
- instances (::Array<::Google::Protobuf::Value, ::Hash>) — 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) — 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) —
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) — If specified, this ExplainRequest will be served by the chosen DeployedModel, overriding Endpoint.traffic_split.
- (response, operation) — Access the result along with the RPC operation
- response (::Google::Cloud::AIPlatform::V1::ExplainResponse)
- operation (::GRPC::ActiveCall::Operation)
- (::Google::Cloud::Error) — if the RPC is aborted.

#raw_predict
def raw_predict(request, options = nil) -> ::Google::Api::HttpBody
def 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.
def raw_predict(request, options = nil) -> ::Google::Api::HttpBody

via a request object, either of type
RawPredictRequest or an equivalent Hash.
- 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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.
def raw_predict(endpoint: nil, http_body: nil) -> ::Google::Api::HttpBody

-
endpoint (::String) — Required. The name of the Endpoint requested to serve the prediction.
Format:
projects/{project}/locations/{location}/endpoints/{endpoint}
-
http_body (::Google::Api::HttpBody, ::Hash) — 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 aDeployedModel
to an Endpoint and use theRawPredict
method.
