DescribeProjectVersions

class Rekognition.Paginator.DescribeProjectVersions

paginator = client.get_paginator('describe_project_versions')

paginate(**kwargs)

Creates an iterator that will paginate through responses from Rekognition.Client.describe_project_versions().

See also: AWS API Documentation

Request Syntax

response_iterator = paginator.paginate(
    ProjectArn='string',
    VersionNames=[
        'string',
    ],
    PaginationConfig={
        'MaxItems': 123,
        'PageSize': 123,
        'StartingToken': 'string'
    }
)

Parameters:

• ProjectArn (string) –

  [REQUIRED]

  The Amazon Resource Name (ARN) of the project that contains the model/adapter you want to describe.

• VersionNames (list) –

  A list of model or project version names that you want to describe. You can add up to 10 model or project version names to the list. If you don’t specify a value, all project version descriptions are returned. A version name is part of a project version ARN. For example, my-model.2020-01-21T09.10.15 is the version name in the following ARN. arn:aws:rekognition:us-east-1:123456789012:project/getting-started/version/my-model.2020-01-21T09.10.15/1234567890123.

  • (string) –

• PaginationConfig (dict) –

  A dictionary that provides parameters to control pagination.

  • MaxItems (integer) –

    The total number of items to return. If the total number of items available is more than the value specified in max-items then a NextToken will be provided in the output that you can use to resume pagination.

  • PageSize (integer) –

    The size of each page.

  • StartingToken (string) –

    A token to specify where to start paginating. This is the NextToken from a previous response.

Return type:

dict

Returns:
