Implementations

impl Builder

pub fn training_image(self, input: impl Into<String>) -> Self

The registry path of the Docker image that contains the training algorithm. For information about Docker registry paths for built-in algorithms, see Algorithms Provided by Amazon SageMaker: Common Parameters. Amazon SageMaker supports both registry/repository[:tag] and registry/repository[@digest] image path formats. For more information, see Using Your Own Algorithms with Amazon SageMaker.

pub fn set_training_image(self, input: Option<String>) -> Self

The registry path of the Docker image that contains the training algorithm. For information about Docker registry paths for built-in algorithms, see Algorithms Provided by Amazon SageMaker: Common Parameters. Amazon SageMaker supports both registry/repository[:tag] and registry/repository[@digest] image path formats. For more information, see Using Your Own Algorithms with Amazon SageMaker.

pub fn training_input_mode(self, input: TrainingInputMode) -> Self

The training input mode that the algorithm supports. For more information about input modes, see Algorithms.

Pipe mode

If an algorithm supports Pipe mode, Amazon SageMaker streams data directly from Amazon S3 to the container.

File mode

If an algorithm supports File mode, SageMaker downloads the training data from S3 to the provisioned ML storage volume, and mounts the directory to the Docker volume for the training container.

You must provision the ML storage volume with sufficient capacity to accommodate the data downloaded from S3. In addition to the training data, the ML storage volume also stores the output model. The algorithm container uses the ML storage volume to also store intermediate information, if any.

For distributed algorithms, training data is distributed uniformly. Your training duration is predictable if the input data objects sizes are approximately the same. SageMaker does not split the files any further for model training. If the object sizes are skewed, training won't be optimal as the data distribution is also skewed when one host in a training cluster is overloaded, thus becoming a bottleneck in training.

FastFile mode

If an algorithm supports FastFile mode, SageMaker streams data directly from S3 to the container with no code changes, and provides file system access to the data. Users can author their training script to interact with these files as if they were stored on disk.

FastFile mode works best when the data is read sequentially. Augmented manifest files aren't supported. The startup time is lower when there are fewer files in the S3 bucket provided.

pub fn set_training_input_mode(self, input: Option<TrainingInputMode>) -> Self

The training input mode that the algorithm supports. For more information about input modes, see Algorithms.

pub fn algorithm_name(self, input: impl Into<String>) -> Self

The name of the resource algorithm to use for the hyperparameter tuning job. If you specify a value for this parameter, do not specify a value for TrainingImage.

pub fn set_algorithm_name(self, input: Option<String>) -> Self

The name of the resource algorithm to use for the hyperparameter tuning job. If you specify a value for this parameter, do not specify a value for TrainingImage.

pub fn metric_definitions(self, input: impl Into<MetricDefinition>) -> Self

Appends an item to metric_definitions.

To override the contents of this collection use set_metric_definitions.

An array of MetricDefinition objects that specify the metrics that the algorithm emits.

pub fn set_metric_definitions(
    self,
    input: Option<Vec<MetricDefinition>>
) -> Self

An array of MetricDefinition objects that specify the metrics that the algorithm emits.

pub fn build(self) -> HyperParameterAlgorithmSpecification

Consumes the builder and constructs a HyperParameterAlgorithmSpecification
