Methods

__construct

Constructor.

Parameters
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.
↳ 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.
