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

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. |

Output only. Time when the Trial's status changed to |
↳ 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. |
