Retail V2 API - Class Google::Cloud::Retail::V2::ModelService::Rest::Client (v0.18.0)

Reference documentation and code samples for the Retail V2 API class Google::Cloud::Retail::V2::ModelService::Rest::Client.

REST client for the ModelService service.

Service for performing CRUD operations on models. Recommendation models contain all the metadata necessary to generate a set of models for the Predict() API. A model is queried indirectly via a ServingConfig, which associates a model with a given Placement (e.g. Frequently Bought Together on Home Page).

This service allows you to do the following:

  • Initiate training of a model.
  • Pause training of an existing model.
  • List all the available models along with their metadata.
  • Control their tuning schedule.

Methods

.configure

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

Configure the ModelService 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 ModelService clients
::Google::Cloud::Retail::V2::ModelService::Rest::Client.configure do |config|
  config.timeout = 10.0
end

#configure

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

Configure the ModelService 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.

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

#create_model

def create_model(request, options = nil) -> ::Gapic::Operation

Creates a new model.

Overloads 
def create_model(request, options = nil) -> ::Gapic::Operation
Pass arguments to create_model via a request object, either of type CreateModelRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Retail::V2::CreateModelRequest, ::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.

def create_model(parent: nil, model: nil, dry_run: nil) -> ::Gapic::Operation
Pass arguments to create_model 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).
