Manages TPU nodes and other resources

TPU API v2alpha1 v2alpha1

Package

Constructors

(constructor)(opts, gaxInstance)

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

Construct an instance of TpuClient.

Parameters

Name	Description
opts	`ClientOptions`
gaxInstance	`typeof gax \| typeof gax.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 TpuClient({fallback: 'rest'}, gax); ```

 : 
  
 Promise 
< {

Initialize the client. Performs asynchronous operations (such as authentication) and prepares the client. This function will be called automatically when any class method is called for the first time, but if you need to initialize it before calling an actual method, feel free to call initialize() directly.

You can await on this method if you want to make sure the client is initialized.

Returns

Type	Description
Promise <{ [name: string]: Function ; }>	{Promise} A promise that resolves to an authenticated service stub.

{Promise} - The promise which resolves to an array. The first element of the array is Array of [AcceleratorType].

Description

AsyncIterable <protos. google.cloud.tpu.v2alpha1.IAcceleratorType >

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [AcceleratorType]. 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](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

{Stream} An object stream which emits an object representing [Node] 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 listNodesAsync() method described below for async iteration which you can stop as needed. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

Lists runtime versions supported by this API.

Parameters

Name	Description
request	`protos. google.cloud.tpu.v2alpha1.IListRuntimeVersionsRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type Description

Promise <[ protos. google.cloud.tpu.v2alpha1.IRuntimeVersion [], protos. google.cloud.tpu.v2alpha1.IListRuntimeVersionsRequest | null, protos. google.cloud.tpu.v2alpha1.IListRuntimeVersionsResponse ]>

{Promise} - The promise which resolves to an array. The first element of the array is Array of [RuntimeVersion]. The client library will perform auto-pagination by default: it will call the API as many times as needed and will merge results from all the pages into this array. Note that it can affect your quota. We recommend using listRuntimeVersionsAsync() method described below for async iteration which you can stop as needed.

Description

AsyncIterable <protos. google.cloud.tpu.v2alpha1.IRuntimeVersion >

{Object} An iterable Object that allows [async iteration](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Iteration_protocols). When you iterate the returned iterable, each element will be an object representing [RuntimeVersion]. 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](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#auto-pagination) for more details and examples.

Parameters

Name	Description
request	`protos. google.cloud.tpu.v2alpha1.IUpdateNodeRequest` The request object that will be sent.
options	`CallOptions` Call options. See CallOptions for more details.

Returns

Type	Description
Promise <[ LROperation <protos. google.cloud.tpu.v2alpha1.INode , protos. google.cloud.tpu.v2alpha1.IOperationMetadata >, protos. google.longrunning.IOperation \| undefined, {} \| undefined ]>	{Promise} - The promise which resolves to an array. The first element of the array is an object representing a long running operation. Its `promise()` method returns a promise you can `await` for. Please see the [documentation](https://github.com/googleapis/gax-nodejs/blob/master/client-libraries.md#long-running-operations) for more details and examples.
