Google Cloud Ai Platform V1 Client - Class VizierServiceClient (0.10.0)

Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class VizierServiceClient.

Service Description: Vertex AI Vizier API.

Vertex AI Vizier is a service to solve blackbox optimization problems, such as tuning machine learning hyperparameters and searching over deep learning architectures.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

$vizierServiceClient = new VizierServiceClient();
try {
    $formattedTrialName = $vizierServiceClient->trialName('[PROJECT]', '[LOCATION]', '[STUDY]', '[TRIAL]');
    $measurement = new Measurement();
    $response = $vizierServiceClient->addTrialMeasurement($formattedTrialName, $measurement);
} finally {
    $vizierServiceClient->close();
}

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

Methods

customJobName

Formats a string containing the fully-qualified path to represent a custom_job resource.

location: projects/{project}/locations/{location}
study: projects/{project}/locations/{location}/studies/{study}
trial: projects/{project}/locations/{location}/studies/{study}/trials/{trial}

The optional $template argument can be supplied to specify a particular pattern, and must match one of the templates listed above. If no $template argument is provided, or if the $template argument does not match one of the templates listed, then parseName will check each of the supported templates, and return the first match.
