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.

Attributes

Name	Description
name	str Output only. Resource name of the Trial assigned by the service.
id	str Output only. The identifier of the Trial assigned by the service.
state	google.cloud.aiplatform_v1beta1.types.Trial.State Output only. The detailed state of the Trial.
parameters	Sequence[google.cloud.aiplatform_v1beta1.types.Trial.Parameter] Output only. The parameters of the Trial.
final_measurement	google.cloud.aiplatform_v1beta1.types.Measurement Output only. The final measurement containing the objective value.
measurements	Sequence[google.cloud.aiplatform_v1beta1.types.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_pb2.Timestamp Output only. Time when the Trial was started.
end_time	google.protobuf.timestamp_pb2.Timestamp Output only. Time when the Trial's status changed to ``SUCCEEDED`` or ``INFEASIBLE``.
client_id	str 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, Vizier will assign it a Trial. The client should evaluate the Trial, complete it, and report back to 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	str Output only. A human readable string describing why the Trial is infeasible. This is set only if Trial state is ``INFEASIBLE``.
custom_job	str Output only. The CustomJob name linked to the Trial. It's set for a HyperparameterTuningJob's Trial.
