Training info of a trial in hyperparameter tuning models.

Fields

trial_id: i64

1-based index of the trial.

start_time_ms: i64

Starting time of the trial.

end_time_ms: i64

Ending time of the trial.

hparams: Option<TrainingOptions>

The hyperprameters selected for this trial.

evaluation_metrics: Option<EvaluationMetrics>

Evaluation metrics of this trial calculated on the test data. Empty in Job API.

status: i32

The status of the trial.

error_message: String

Error message for FAILED and INFEASIBLE trial.

training_loss: Option<f64>

Loss computed on the training data at the end of trial.

eval_loss: Option<f64>

Loss computed on the eval data at the end of trial.

hparam_tuning_evaluation_metrics: Option<EvaluationMetrics>

Hyperparameter tuning evaluation metrics of this trial calculated on the eval data. Unlike evaluation_metrics, only the fields corresponding to the hparam_tuning_objectives are set.

Implementations

impl HparamTuningTrial

pub fn status(&self) -> TrialStatus

Returns the enum value of status, or the default if the field is set to an invalid enum value.

pub fn set_status(&mut self, value: TrialStatus)

Sets status to the provided enum value.

Trait Implementations

impl Clone for HparamTuningTrial

fn clone(&self) -> HparamTuningTrial

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HparamTuningTrial

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HparamTuningTrial

fn default() -> Self

Returns the “default value” for a type.

impl Message for HparamTuningTrial

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for HparamTuningTrial

fn eq(&self, other: &HparamTuningTrial) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
