Struct HyperbandStrategyConfigBuilder

#[non_exhaustive]
pub struct HyperbandStrategyConfigBuilder { /* private fields */ }

A builder for HyperbandStrategyConfig.

Implementations

impl HyperbandStrategyConfigBuilder

pub fn min_resource(self, input: i32) -> Self

The minimum number of resources (such as epochs) that can be used by a training job launched by a hyperparameter tuning job. If the value for MinResource has not been reached, the training job is not stopped by Hyperband.

pub fn set_min_resource(self, input: Option<i32>) -> Self

The minimum number of resources (such as epochs) that can be used by a training job launched by a hyperparameter tuning job. If the value for MinResource has not been reached, the training job is not stopped by Hyperband.

pub fn get_min_resource(&self) -> &Option<i32>

The minimum number of resources (such as epochs) that can be used by a training job launched by a hyperparameter tuning job. If the value for MinResource has not been reached, the training job is not stopped by Hyperband.

pub fn max_resource(self, input: i32) -> Self

The maximum number of resources (such as epochs) that can be used by a training job launched by a hyperparameter tuning job. Once a job reaches the MaxResource value, it is stopped. If a value for MaxResource is not provided, and Hyperband is selected as the hyperparameter tuning strategy, HyperbandTraining attempts to infer MaxResource from the following keys (if present) in StaticsHyperParameters:

• epochs

• numepochs

• n-epochs

• n_epochs

• num_epochs

If HyperbandStrategyConfig is unable to infer a value for MaxResource, it generates a validation error. The maximum value is 20,000 epochs. All metrics that correspond to an objective metric are used to derive early stopping decisions. For distributed training jobs, ensure that duplicate metrics are not printed in the logs across the individual nodes in a training job. If multiple nodes are publishing duplicate or incorrect metrics, training jobs may make an incorrect stopping decision and stop the job prematurely.

pub fn build(self) -> HyperbandStrategyConfig

Consumes the builder and constructs a HyperbandStrategyConfig.

Trait Implementations

impl Clone for HyperbandStrategyConfigBuilder

fn clone(&self) -> HyperbandStrategyConfigBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HyperbandStrategyConfigBuilder

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

Formats the value using the given formatter.

impl Default for HyperbandStrategyConfigBuilder

fn default() -> HyperbandStrategyConfigBuilder

Returns the “default value” for a type.

impl PartialEq for HyperbandStrategyConfigBuilder

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

Tests for self and other values to be equal, and is used by ==.

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

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