HyperParameterTuningResourceConfig
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.
Contents
- AllocationStrategy
-
The strategy that determines the order of preference for resources specified in
InstanceConfigsused in hyperparameter optimization.Type: String
Valid Values:
PrioritizedRequired: No
- InstanceConfigs
-
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
AllocationStrategycontrols the order in which multiple configurations provided inInstanceConfigsare used.Note
If you only want to use a single instance configuration inside the
HyperParameterTuningResourceConfigAPI, do not provide a value forInstanceConfigs. Instead, useInstanceType,VolumeSizeInGBandInstanceCount. If you useInstanceConfigs, do not provide values forInstanceType,VolumeSizeInGBorInstanceCount.Type: Array of HyperParameterTuningInstanceConfig objects
Array Members: Minimum number of 1 item. Maximum number of 6 items.
Required: No
- InstanceCount
-
The number of compute instances of type
InstanceTypeto use. For distributed training, select a value greater than 1.Type: Integer
Valid Range: Minimum value of 0.
Required: No
- InstanceType
-
The instance type used to run hyperparameter optimization tuning jobs. See descriptions of instance types for more information.

- VolumeKmsKeyId
-
A key used by AWS 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 AWS Key Management Service, see KMS encryption for more information. Type: String
Length Constraints: Maximum length of 2048.
Pattern:
^[a-zA-Z0-9:/_-]*$Required: No
- VolumeSizeInGB
-
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
InstanceConfigsis also specified.Some instance types have a fixed total local storage size. If you select one of these instances for training,
VolumeSizeInGBcannot 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.
Type: Integer
Valid Range: Minimum value of 0.
