| Name | Description |
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<Trial\Parameter>
Output only. The parameters of the Trial. |
↳ final_measurement |
Measurement
Output only. The final measurement containing the objective value. |
↳ measurements |
array<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. |

Google\Protobuf\Timestamp
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. |

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

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 |
