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

A message representing a Trial. A Trial contains a unique set of Parameters that has been or will be evaluated, along with the objective metrics got by running the Trial.

Generated from protobuf message google.cloud.aiplatform.v1.Trial

Namespace

Methods

__construct

Constructor.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ name string

Output only. Resource name of the Trial assigned by the service.

↳ id string

Output only. The identifier of the Trial assigned by the service.

↳ state int

Output only. The detailed state of the Trial.

↳ parameters array<Google\Cloud\AIPlatform\V1\Trial\Parameter>

Output only. The parameters of the Trial.

↳ final_measurement Google\Cloud\AIPlatform\V1\Measurement

Output only. The final measurement containing the objective value.

↳ measurements array<Google\Cloud\AIPlatform\V1\Measurement>

Output only. A list of measurements that are strictly lexicographically ordered by their induced tuples (steps, elapsed_duration). These are used for early stopping computations.

↳ start_time Google\Protobuf\Timestamp

Output only. Time when the Trial was started.

↳ end_time Google\Protobuf\Timestamp

Output only. Time when the Trial's status changed to SUCCEEDED or INFEASIBLE.

↳ client_id string

Output only. The identifier of the client that originally requested this Trial. Each client is identified by a unique client_id. When a client asks for a suggestion, Vertex AI Vizier will assign it a Trial. The client should evaluate the Trial, complete it, and report back to Vertex AI Vizier. If suggestion is asked again by same client_id before the Trial is completed, the same Trial will be returned. Multiple clients with different client_ids can ask for suggestions simultaneously, each of them will get their own Trial.

↳ infeasible_reason string

Output only. A human readable string describing why the Trial is infeasible. This is set only if Trial state is INFEASIBLE.

↳ custom_job string

Output only. The CustomJob name linked to the Trial. It's set for a HyperparameterTuningJob's Trial.

↳ web_access_uris array|Google\Protobuf\Internal\MapField

Output only. URIs for accessing interactive shells (one URI for each training node). Only available if this trial is part of a HyperparameterTuningJob and the job's trial_job_spec.enable_web_access field is true. The keys are names of each node used for the trial; for example, workerpool0-0 for the primary node, workerpool1-0 for the first node in the second worker pool, and workerpool1-1 for the second node in the second worker pool. The values are the URIs for each node's interactive shell.
