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.
BatchPredictOperation
type
BatchPredictOperation
struct
{
// contains filtered or unexported fields
}
BatchPredictOperation manages a long-running operation from BatchPredict.
func (*BatchPredictOperation) Done
func
(
op
*
BatchPredictOperation
)
Done
()
bool
Done reports whether the long-running operation has completed.
func (*BatchPredictOperation) Metadata
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
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
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
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.

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

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
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.

DeployModel deploys a model. If a model is already deployed, deploying it with the same parameters has no effect. Deploying with different parametrs (as e.g. changing
node_number) will reset the deployment state without pausing the model’s availability.
Only applicable for Text Classification, Image Object Detection , Tables, and Image Segmentation; all other domains manage deployment automatically.
Returns an empty response in the response field when it completes.

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 (*ImportDataOperation) Name

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.

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.

BatchPredict perform a batch prediction. Unlike the online Predict, batch prediction result won’t be immediately available in the response. Instead, a long running operation object is returned. User can poll the operation result via GetOperation method. Once the operation is done, BatchPredictResult is returned in the response field. Available for following ML scenarios:
