public interface ResourceConfig

Specifies the resources, ML compute instances, and ML storage volumes to deploy for model training.

Method Detail

getInstanceCount

java.lang.Number getInstanceCount()

The number of ML compute instances to use.

Default: 1 instance.

getInstanceType

InstanceType getInstanceType()

ML compute instance type.

To provide an instance type from the task input, supply an instance type in the following way where the value in the task input is an EC2 instance type prepended with "ml.":

 new InstanceType(JsonPath.stringAt("$.path.to.instanceType"));
 

Default: ec2.InstanceType(ec2.InstanceClass.M4, ec2.InstanceType.XLARGE)

getVolumeSize

Size getVolumeSize()

Size of the ML storage volume that you want to provision.

Default: 10 GB EBS volume.

getVolumeEncryptionKey

default IKey getVolumeEncryptionKey()

KMS key that Amazon SageMaker uses to encrypt data on the storage volume attached to the ML compute instance(s) that run the training job.

Default: - Amazon SageMaker uses the default KMS key for Amazon S3 for your role's account

builder

static ResourceConfig.Builder builder()

Returns:

a ResourceConfig.Builder of ResourceConfig
