Class v2alpha1.TpuClient (2.2.0)

Manages TPU nodes and other resources

TPU API v2alpha1 v2alpha1

Package

@google-cloud/tpu

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); ```

initialize()

initialize(): Promise<{
        [name: string]: Function;

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.
