public static final class VizierServiceGrpc . VizierServiceStub extends AbstractAsyncStub<VizierServiceGrpc . VizierServiceStub >
Vertex Vizier API.
Vizier service is a GCP service to solve blackbox optimization problems,
such as tuning machine learning hyperparameters and searching over deep
learning architectures.

Methods
public void addTrialMeasurement ( AddTrialMeasurementRequest request , StreamObserver<Trial> responseObserver )
Adds a measurement of the objective metrics to a Trial. This measurement
is assumed to have been taken before the Trial is complete.
Parameters
protected VizierServiceGrpc . VizierServiceStub build ( Channel channel , CallOptions callOptions )
Parameters
Name Description
channel io.grpc.Channel
callOptions io.grpc.CallOptions
Returns
Overrides
io.grpc.stub.AbstractStub.build(io.grpc.Channel,io.grpc.CallOptions)
public void checkTrialEarlyStoppingState ( CheckTrialEarlyStoppingStateRequest request , StreamObserver<Operation> responseObserver )
Checks whether a Trial should stop or not. Returns a
long-running operation. When the operation is successful,
it will contain a
CheckTrialEarlyStoppingStateResponse .
Parameters
public void completeTrial ( CompleteTrialRequest request , StreamObserver<Trial> responseObserver )
Marks a Trial as complete.
Parameters
public void createStudy ( CreateStudyRequest request , StreamObserver<Study> responseObserver )
Creates a Study. A resource name will be generated after creation of the
Study.
Parameters
public void createTrial ( CreateTrialRequest request , StreamObserver<Trial> responseObserver )
Adds a user provided Trial to a Study.
Parameters
public void deleteStudy ( DeleteStudyRequest request , StreamObserver<Empty> responseObserver )
Parameters
public void deleteTrial ( DeleteTrialRequest request , StreamObserver<Empty> responseObserver )
Parameters
public void getStudy ( GetStudyRequest request , StreamObserver<Study> responseObserver )
Parameters
public void getTrial ( GetTrialRequest request , StreamObserver<Trial> responseObserver )
Parameters
public void listOptimalTrials ( ListOptimalTrialsRequest request , StreamObserver<ListOptimalTrialsResponse> responseObserver )
Parameters
public void listStudies ( ListStudiesRequest request , StreamObserver<ListStudiesResponse> responseObserver )
Lists all the studies in a region for an associated project.
Parameters
public void listTrials ( ListTrialsRequest request , StreamObserver<ListTrialsResponse> responseObserver )
Lists the Trials associated with a Study.
Parameters
public void lookupStudy ( LookupStudyRequest request , StreamObserver<Study> responseObserver )
Looks a study up using the user-defined display_name field instead of the
fully qualified resource name.
Parameters
public void stopTrial ( StopTrialRequest request , StreamObserver<Trial> responseObserver )
Parameters
public void suggestTrials ( SuggestTrialsRequest request , StreamObserver<Operation> responseObserver )
Adds one or more Trials to a Study, with parameter values
suggested by Vertex Vizier. Returns a long-running
operation associated with the generation of Trial suggestions.
When this long-running operation succeeds, it will contain
a SuggestTrialsResponse .
