Documentation

Overview

Package automl is an auto-generated package for the Cloud AutoML API.

Train high-quality custom machine learning models with minimum effort and machine learning expertise.

Use of Context

The ctx passed to NewClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

For information about setting deadlines, reusing contexts, and more please visit pkg.go.dev/cloud.google.com/go.

Functions

func DefaultAuthScopes 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type BatchPredictOperation added in v0.48.0 

type BatchPredictOperation struct {
	// contains filtered or unexported fields
}

BatchPredictOperation manages a long-running operation from BatchPredict.

func (*BatchPredictOperation) Done added in v0.48.0 

func (op *BatchPredictOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*BatchPredictOperation) Metadata added in v0.48.0 

func (op *BatchPredictOperation) Metadata() (*automlpb.OperationMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*BatchPredictOperation) Name added in v0.48.0 

func (op *BatchPredictOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*BatchPredictOperation) Poll added in v0.48.0 

func (op *BatchPredictOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*automlpb.BatchPredictResult, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*BatchPredictOperation) Wait added in v0.48.0 

func (op *BatchPredictOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*automlpb.BatchPredictResult, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

type CallOptions 

type CallOptions struct {
	CreateDataset        []gax.CallOption
	GetDataset           []gax.CallOption
	ListDatasets         []gax.CallOption
	UpdateDataset        []gax.CallOption
	DeleteDataset        []gax.CallOption
	ImportData           []gax.CallOption
	ExportData           []gax.CallOption
	GetAnnotationSpec    []gax.CallOption
	CreateModel          []gax.CallOption
	GetModel             []gax.CallOption
	ListModels           []gax.CallOption
	DeleteModel          []gax.CallOption
	UpdateModel          []gax.CallOption
	DeployModel          []gax.CallOption
	UndeployModel        []gax.CallOption
	ExportModel          []gax.CallOption
	GetModelEvaluation   []gax.CallOption
	ListModelEvaluations []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

type Client 

type Client struct {

	// LROClient is used internally to handle longrunning operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient

	// The call options for this service.
	CallOptions *CallOptions
	// contains filtered or unexported fields
}

Client is a client for interacting with Cloud AutoML API.

Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

func NewClient 

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

NewClient creates a new auto ml client.

AutoML Server API.

The resource names are assigned by the server. The server never reuses names that it has created after the resources with those names are deleted.

An ID of a resource is the last element of the item’s resource name. For projects/{project_id}/locations/{location_id}/datasets/{dataset_id}, then the id for the item is {dataset_id}.

Currently the only supported location_id is “us-central1”.

On any input that is documented to expect a string parameter in snake_case or kebab-case, either of those cases is accepted.

Example 
package main

import (
	"context"

	automl "cloud.google.com/go/automl/apiv1"
)

func main() {
	ctx := context.Background()
	c, err := automl.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use client.
	_ = c
}

Output:

func (*Client) Close 

func (c *Client) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*Client) Connection 

func (c *Client) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated.

func (*Client) CreateDataset 

func (c *Client) CreateDataset(ctx context.Context, req *automlpb.CreateDatasetRequest, opts ...gax.CallOption) (*CreateDatasetOperation, error)
