Description

Submits an asynchronous sampling operation to generate text or compute log-probabilities from the model associated with the specified training session. The session must be in Running or Blocked state. Use GetSamplingOperationResult to poll for the result.

Parameters

-ClientConfig <AmazonSageMakerTrainingSessionRuntimeConfig>
Amazon.PowerShell.Cmdlets.SMTSR.AmazonSageMakerTrainingSessionRuntimeClientCmdlet.ClientConfig
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-OperationConfig_ComputeLogprobs_ModelPackageArn <String>
The ARN of the model package whose checkpoint this operation should run against. Must be a valid SageMaker model package ARN in the format arn:aws:sagemaker:REGION:ACCOUNT:model-package/PACKAGE_NAME/VERSION. When absent, the operation runs against the session's latest checkpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-OperationConfig_ComputeLogprobs_Prompt_Chunk <EncodedTextChunk[]>
The ordered list of encoded text chunks forming the input sequence. Starting with version 4 of the SDK this property will default to null. If no data for this property is returned from the service the property will also be null. This was changed to improve performance and allow the SDK and caller to distinguish between a property not set or a property being empty to clear out a value. To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesOperationConfig_ComputeLogprobs_Prompt_Chunks
-OperationConfig_LoadWeightsForSampling_ModelPackageArn <String>
The ARN of the model package containing the weights to load for sampling. Must be a valid SageMaker model package ARN in the format arn:aws:sagemaker:REGION:ACCOUNT:model-package/PACKAGE_NAME/VERSION. The model package must belong to the same AWS account as the training session.

-OperationConfig_Sample_ModelPackageArn <String>
The ARN of the model package whose checkpoint this sample should run against. Must be a valid SageMaker model package ARN in the format arn:aws:sagemaker:REGION:ACCOUNT:model-package/PACKAGE_NAME/VERSION. When absent, the sample runs against the session's latest checkpoint.

-OperationConfig_Sample_SamplingParams_Stop <String[]>
The list of stop sequences that terminate generation when encountered in the output. Starting with version 4 of the SDK this property will default to null.

To retain the previous SDK behavior set the AWSConfigs.InitializeCollections static property to true.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)

-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'OperationId'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.SageMakerTrainingSessionRuntime.Model.ExecuteSamplingOperationResponse). Specifying the name of a property of type Amazon.SageMakerTrainingSessionRuntime.Model.ExecuteSamplingOperationResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAK
-Credential <AWSCredentials>

Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-EndpointUrl <String>
The endpoint to make the call against.Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required?False
Position?Named
Accept pipeline input?True (ByValue, ByPropertyName)
-ProfileLocation <String>
Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials.If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required?False

-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
