 ** AlgorithmName **   <a name="sagemaker-Type-SourceAlgorithm-AlgorithmName"></a>
The name of an algorithm that was used to create the model package. The algorithm must be either an algorithm resource in your SageMaker account or an algorithm in Amazon Marketplace that you are subscribed to.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 170.  
Pattern: `(arn:aws[a-z\-]*:sagemaker:[a-z0-9\-]*:[0-9]{12}:[a-z\-]*\/)?([a-zA-Z0-9]([a-zA-Z0-9-]){0,62})(?<!-)`   
Required: Yes

 ** ModelDataETag **   <a name="sagemaker-Type-SourceAlgorithm-ModelDataETag"></a>
The ETag associated with Model Data URL.  
Type: String  
Required: No

 ** ModelDataSource **   <a name="sagemaker-Type-SourceAlgorithm-ModelDataSource"></a>
Specifies the location of ML model data to deploy during endpoint creation.  
Type: [ModelDataSource](API_ModelDataSource.md) object  
Required: No

 ** ModelDataUrl **   <a name="sagemaker-Type-SourceAlgorithm-ModelDataUrl"></a>
The Amazon S3 path where the model artifacts, which result from model training, are stored. This path must point to a single `gzip` compressed tar archive (`.tar.gz` suffix).  
The model artifacts must be in an S3 bucket that is in the same Amazon region as the algorithm.
Type: String
