Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the PredictionService Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# 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.

def raw_predict(request, options = nil) -> ::Google::Api::HttpBody
def raw_predict(endpoint: nil, http_body: nil) -> ::Google::Api::HttpBody

Overloads 
def 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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

    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.

  • (::Google::Cloud::Error) — if the RPC is aborted.
Example

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::Client.new

# Create an input stream.
input = Gapic::StreamInput.new

# Call the streaming_predict method to start streaming.
output = client.streaming_predict input

# Send requests on the stream. For each request object, set fields by
# passing keyword arguments. Be sure to close the stream when done.
input << Google::Cloud::AIPlatform::V1::StreamingPredictRequest.new
input << Google::Cloud::AIPlatform::V1::StreamingPredictRequest.new
input.close

# The returned object is a streamed enumerable yielding elements of type
# ::Google::Cloud::AIPlatform::V1::StreamingPredictResponse
output.each do |current_response|
  p current_response
end

#streaming_raw_predict

def streaming_raw_predict(request, options = nil) { |response, operation| ... } -> ::Enumerable<::Google::Cloud::AIPlatform::V1::StreamingRawPredictResponse>

Perform a streaming online prediction request through gRPC.

Parameters
Yields
  • (response, operation) — Access the result along with the RPC operation
