HyperParameterTuningResourceConfig
import type { HyperParameterTuningResourceConfig } from "https://aws-api.deno.dev/v0.4/services/sagemaker.ts?docs=full";
The configuration of resources, including compute instances and storage volumes for use in training jobs launched by hyperparameter tuning jobs.
HyperParameterTuningResourceConfig
is similar to ResourceConfig
, but has the additional InstanceConfigs
and AllocationStrategy
fields to allow for flexible instance management.
Specify one or more instance types, count, and the allocation strategy for instance selection.
Note:
HyperParameterTuningResourceConfig
supports the capabilities of ResourceConfig
with the exception of KeepAlivePeriodInSeconds
.
Hyperparameter tuning jobs use warm pools by default, which reuse clusters between training jobs.
§Properties
The strategy that determines the order of preference for resources specified in InstanceConfigs
used in hyperparameter optimization.
A list containing the configuration(s) for one or more resources for processing hyperparameter jobs.
These resources include compute instances and storage volumes to use in model training jobs launched by hyperparameter tuning jobs.
The AllocationStrategy
controls the order in which multiple configurations provided in InstanceConfigs
are used.
Note:
If you only want to use a single instance configuration inside the HyperParameterTuningResourceConfig
API, do not provide a value for InstanceConfigs
.
Instead, use InstanceType
, VolumeSizeInGB
and InstanceCount
.
If you use InstanceConfigs
, do not provide values for InstanceType
, VolumeSizeInGB
or InstanceCount
.
The number of compute instances of type InstanceType
to use.
For distributed training, select a value greater than 1.
The instance type used to run hyperparameter optimization tuning jobs. See descriptions of instance types for more information.
A key used by Amazon Web Services Key Management Service to encrypt data on the storage volume attached to the compute instances used to run the training job. You can use either of the following formats to specify a key.
KMS Key ID:
"1234abcd-12ab-34cd-56ef-1234567890ab"
Amazon Resource Name (ARN) of a KMS key:
"arn:aws:kms:us-west-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab"
Some instances use local storage, which use a hardware module to encrypt storage volumes.
If you choose one of these instance types, you cannot request a VolumeKmsKeyId
.
For a list of instance types that use local storage, see instance store volumes.
For more information about Amazon Web Services Key Management Service, see KMS encryption for more information.
The volume size in GB for the storage volume to be used in processing hyperparameter optimization jobs (optional).
These volumes store model artifacts, incremental states and optionally, scratch space for training algorithms.
Do not provide a value for this parameter if a value for InstanceConfigs
is also specified.
Some instance types have a fixed total local storage size.
If you select one of these instances for training, VolumeSizeInGB
cannot be greater than this total size.
For a list of instance types with local instance storage and their sizes, see instance store volumes.
Note: SageMaker supports only the General Purpose SSD (gp2) storage volume type.
