Class v2beta.ModelServiceClient (3.1.0)

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. v2beta

Constructors

(constructor)(opts, gaxInstance)

constructor(opts?: ClientOptions, gaxInstance?: typeof gax | typeof gax.fallback);

Construct an instance of ModelServiceClient.

Parameters
Name	Description
`opts`	`ClientOptions`
`gaxInstance`	`typeof gax \| typeof fallback` : loaded instance of `google-gax`. Useful if you need to avoid loading the default gRPC version and want to use the fallback HTTP implementation. Load only fallback version and pass it to the constructor: ``` const gax = require('google-gax/build/src/fallback'); // avoids loading google-gax with gRPC const client = new ModelServiceClient({fallback: true}, gax); ```

cancelOperation(request, options, callback)

Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an value with a of 1, corresponding to Code.CANCELLED.

Parameters
Name	Description
`request`	`CancelOperationRequest` The request object that will be sent.
`options`	`CallOptions \| Callback<protos.google.protobuf.Empty, protos.google.longrunning.CancelOperationRequest, {} \| undefined \| null>` Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.
`callback`	`Callback<protos.google.longrunning.CancelOperationRequest, protos.google.protobuf.Empty, {} \| undefined \| null>` The function which will be called with the result of the API call. {Promise} - The promise which resolves when API call finishes.

`AsyncIterable<protos.google.cloud.retail.v2beta.IModel>`	{Object} An iterable Object that allows async iteration. When you iterate the returned iterable, each element will be an object representing . The API will be called under the hood as needed, once per the page, so you can stop the iteration when you don't need more results. Please see the documentation for more details and examples.

Example


  /**

   * It will require modifications to work.
   * It may require correct/in-range values for request initialization.
   * TODO(developer): Uncomment these variables before running the sample.
   */
  /**
   *  Required. The parent for which to list models.
   *  Format:
   *  `projects/{project_number}/locations/{location_id}/catalogs/{catalog_id}`
   */
  // const parent = 'abc123'
  /**
   *  Optional. Maximum number of results to return. If unspecified, defaults
   *  to 50. Max allowed value is 1000.
   */

   *  call. Provide this to retrieve the subsequent page.
   */
  // const pageToken = 'abc123'

  // Imports the Retail library
  const {ModelServiceClient} = require('@google-cloud/retail').v2beta;

  // Instantiates a client
  const retailClient = new ModelServiceClient();

  async function callListModels() {
    // Construct request
    const request = {
      parent,

listModelsStream(request, options)

listModelsStream(request?: protos.google.cloud.retail.v2beta.IListModelsRequest, options?: CallOptions): Transform;

Parameters
Name	Description
`request`	`IListModelsRequest` The request object that will be sent.
`options`	`CallOptions` Call options. See CallOptions for more details.

Returns
Type	Description
`Transform`	{Stream} An object stream which emits an object representing on 'data' event. The client library will perform auto-pagination by default: it will call the API as many times as needed. Note that it can affect your quota. We recommend using `listModelsAsync()` method described below for async iteration which you can stop as needed. Please see the documentation for more details and examples.

listOperationsAsync(request, options)

listOperationsAsync(request: protos.google.longrunning.ListOperationsRequest, options?: gax.CallOptions): AsyncIterable<protos.google.longrunning.ListOperationsResponse>;

For-await-of syntax is used with the iterable to recursively get response element on-demand.

Parameters
Name	Description
`request`	`ListOperationsRequest` The request object that will be sent.
`options`	`CallOptions` Optional parameters. You can override the default settings for this call, e.g, timeout, retries, paginations, etc. See gax.CallOptions for the details.

Returns
Type	Description
`AsyncIterable<protos.google.longrunning.ListOperationsResponse>`	{Object} An iterable Object that conforms to iteration protocols.

Example


const client = longrunning.operationsClient();
for await (const response of client.listOperationsAsync(request));
// doThingsWith(response)
