Full resource name of the format: # \\{name=projects/*/locations/global/catalogs/default_catalog/placements/*} # The ID of the Recommendations AI placement. Before you can request # predictions from your model, you must create at least one placement for it. # For more information, see [Managing # placements](https://cloud.google.com/retail/recommendations-ai/docs/manage-placements). # # The full list of available placements can be seen at # https://console.cloud.google.com/recommendation/catalogs/default_catalog/placements # @param user_event [::Google::Cloud::Retail::V2::UserEvent, ::Hash] # Required. Context about the user, what they are looking at and what action # they took to trigger the predict request. Note that this user event detail # won't be ingested to userEvent logs. Thus, a separate userEvent write # request is required for event logging. # @param page_size [::Integer] # Maximum number of results to return per page. Set this property # to the number of prediction results needed. If zero, the service will # choose a reasonable default. The maximum allowed value is 100. Values # above 100 will be coerced to 100. # @param page_token [::String] # The previous PredictResponse.next_page_token. # @param filter [::String] # Filter for restricting prediction results with a length limit of 5,000 # characters. Accepts values for tags and the `filterOutOfStockItems` flag. # # * Tag expressions. Restricts predictions to products that match all of the # specified tags. Boolean operators `OR` and `NOT` are supported if the # expression is enclosed in parentheses, and must be separated from the # tag values by a space. `-"tagA"` is also supported and is equivalent to # `NOT "tagA"`. Tag values must be double quoted UTF-8 encoded strings # with a size limit of 1,000 characters. # # Note: "Recently viewed" models don't support tag filtering at the # moment. # # * filterOutOfStockItems. Restricts predictions to products that do not # have a # stockState value of OUT_OF_STOCK. # # Examples: # # * tag=("Red" OR "Blue") tag="New-Arrival" tag=(NOT "promotional") # * filterOutOfStockItems tag=(-"promotional") # * filterOutOfStockItems # # If your filter blocks all prediction results, nothing will be returned. If # you want generic (unfiltered) popular products to be returned instead, set # `strictFiltering` to false in `PredictRequest.params`. # @param validate_only [::Boolean] # Use validate only mode for this prediction query. If set to true, a # dummy model will be used that returns arbitrary products. # Note that the validate only mode should only be used for testing the API, # or if the model is not ready. # @param params [::Hash{::String => ::Google::Protobuf::Value, ::Hash}] # Additional domain specific parameters for the predictions. # # Allowed values: # # * `returnProduct`: Boolean. If set to true, the associated product # object will be returned in the `results.metadata` field in the # prediction response. # * `returnScore`: Boolean. If set to true, the prediction 'score' # corresponding to each returned product will be set in the # `results.metadata` field in the prediction response. The given # 'score' indicates the probability of an product being clicked/purchased # given the user's context and history. # * `strictFiltering`: Boolean. True by default. If set to false, the service # will return generic (unfiltered) popular products instead of empty if # your filter blocks all prediction results. # * `priceRerankLevel`: String. Default empty. If set to be non-empty, then # it needs to be one of {'no-price-reranking', 'low-price-reranking', # 'medium-price-reranking', 'high-price-reranking'}. This gives # request-level control and adjusts prediction results based on product # price. # * `diversityLevel`: String. Default empty. If set to be non-empty, then # it needs to be one of {'no-diversity', 'low-diversity', # 'medium-diversity', 'high-diversity', 'auto-diversity'}. This gives # request-level control and adjusts prediction results based on product # category. # @param labels [::Hash{::String => ::String}] # The labels applied to a resource must meet the following requirements: # # * Each resource can have multiple labels, up to a maximum of 64. # * Each label must be a key-value pair. # * Keys have a minimum length of 1 character and a maximum length of 63 # characters, and cannot be empty. Values can be empty, and have a maximum # length of 63 characters. # * Keys and values can contain only lowercase letters, numeric characters, # underscores, and dashes. All characters must use UTF-8 encoding, and # international characters are allowed. # * The key portion of a label must be unique. However, you can use the same # key with multiple resources. # * Keys must start with a lowercase letter or international character. # # See [Google Cloud # Document](https://cloud.google.com/resource-manager/docs/creating-managing-labels#requirements) # for more details. # # @yield [response, operation] Access the result along with the RPC operation # @yieldparam response [::Google::Cloud::Retail::V2::PredictResponse] # @yieldparam operation [::GRPC::ActiveCall::Operation] # # @return [::Google::Cloud::Retail::V2::PredictResponse] # # @raise [::Google::Cloud::Error] if the RPC is aborted. # def predict request, options = nil raise ::ArgumentError, "request must be provided" if request.nil? request = ::Gapic::Protobuf.coerce request, to: ::Google::Cloud::Retail::V2::PredictRequest # Converts hash and nil to an options object options = ::Gapic::CallOptions.new(**options.to_h) if options.respond_to? :to_h # Customize the options with defaults metadata = @config.rpcs.predict.metadata.to_h # Set x-goog-api-client and x-goog-user-project headers metadata[:"x-goog-api-client"] ||= ::Gapic::Headers.x_goog_api_client \ lib_name: @config.lib_name, lib_version: @config.lib_version, gapic_version: ::Google::Cloud::Retail::V2::VERSION metadata[:"x-goog-user-project"] = @quota_project_id if @quota_project_id header_params = { "placement" => request.placement } request_params_header = header_params.map { |k, v| "#{k}=#{v}" }.join("&") metadata[:"x-goog-request-params"] ||= request_params_header options.apply_defaults timeout: @config.rpcs.predict.timeout, metadata: metadata, retry_policy: @config.rpcs.predict.retry_policy options.apply_defaults timeout: @config.timeout, metadata: @config.metadata, retry_policy: @config.retry_policy @prediction_service_stub.call_rpc :predict, request, options: options do |response, operation| yield response, operation if block_given? return response end rescue ::GRPC::BadStatus => e raise ::Google::Cloud::Error.from_error(e) end ## # Configuration class for the PredictionService API. # # This class represents the configuration for PredictionService, # providing control over timeouts, retry behavior, logging, transport # parameters, and other low-level controls.
