Methods

createExtractJob(destination, options)

createExtractJob(destination: string | File, options?: CreateExtractJobOptions): Promise<JobResponse>;

Export model to Cloud Storage.

See Jobs: insert API Documentation

Parameters
NameDescription
destination string | File

Where the model should be exported to. A string or object.

options CreateExtractJobOptions

The configuration object. For all extract job options, see [CreateExtractJobOptions]https://cloud.google.com/bigquery/docs/reference/rest/v2/Job#JobConfigurationExtract.

Returns
TypeDescription
Promise<JobResponse>

{Promise

Example 

const {BigQuery} = require('@google-cloud/bigquery');
const bigquery = new BigQuery();
const dataset = bigquery.dataset('my-dataset');
const model = dataset.model('my-model');

const extractedModel = 'gs://my-bucket/extracted-model';

function callback(err, job, apiResponse) {
  // `job` is a Job object that can be used to check the status of the
  // request.
}

//-
// To use the default options, just pass a string or a {@link
https://googleapis.dev/nodejs/storage/latest/File.html File}
object.
//
// Note: The default format is 'ML_TF_SAVED_MODEL'.
//-
model.createExtractJob(extractedModel, callback);
