CreateModel (updated)

Link ¶
Changes (request)

{'Description': 'string', 'Tags': [{'Key': 'string', 'Value': 'string'}]}

Creates a new version of a model within an an Amazon Lookout for Vision project. CreateModel is an asynchronous operation in which Amazon Lookout for Vision trains, tests, and evaluates a new version of a model.

To get the current status, check the Status field returned in the response from DescribeModel .

If the project has a single dataset, Amazon Lookout for Vision internally splits the dataset to create a training and a test dataset. If the project has a training and a test dataset, Lookout for Vision uses the respective datasets to train and test the model.

After training completes, the evaluation metrics are stored at the location specified in OutputConfig .

This operation requires permissions to perform the lookoutvision:CreateModel operation. If you want to tag your model, you also require permission to the lookoutvision:TagResource operation.

Request Syntax

client.create_model(
    ProjectName='string',
    Description='string',
    ClientToken='string',
    OutputConfig={
        'S3Location': {
            'Bucket': 'string',

        },
    ]
)

type ProjectName

string

param ProjectName

[REQUIRED]

The name of the project in which you want to create a model version.

type Description

string

param Description

A description for the version of the model.

type ClientToken

string

param ClientToken

ClientToken is an idempotency token that ensures a call to CreateModel completes only once. You choose the value to pass. For example, An issue, such as an network outage, might prevent you from getting a response from CreateModel . In this case, safely retry your call to CreateModel by using the same ClientToken parameter value. An error occurs if the other input parameters are not the same as in the first request. Using a different value for ClientToken is considered a new call to CreateModel . An idempotency token is active for 8 hours.

This field is autopopulated if not provided.

type OutputConfig

dict

param OutputConfig

[REQUIRED]

The location where Amazon Lookout for Vision saves the training results.

S3Location (dict) -- [REQUIRED]

The S3 location for the output.
- Bucket (string) -- [REQUIRED]
  
  The S3 bucket that contain the manifest file.
- Prefix (string) --
  
  The path and name of the manifest file with the S3 bucket.

type KmsKeyId

string

param KmsKeyId

The identifier of the AWS Key Management Service (AWS KMS) customer master key (CMK) to use for encypting the model. If this parameter is not specified, the model is encrypted by a key that AWS owns and manages.

type Tags

list

param Tags

A set of tags (key-value pairs) that you want to attach to the model.

(dict) --

A key and value pair that is attached to the specified Amazon Lookout for Vision model.
- Key (string) -- [REQUIRED]
