list_models

list_models(**kwargs)

Lists the versions of a model in an Amazon Lookout for Vision project.

The ListModels operation is eventually consistent. Recent calls to CreateModel might take a while to appear in the response from ListProjects .

This operation requires permissions to perform the lookoutvision:ListModels operation.

Request Syntax

response = client.list_models(
    ProjectName='string',
    NextToken='string',
    MaxResults=123
)

Parameters

• ProjectName (string) --

  [REQUIRED]

  The name of the project that contains the model versions that you want to list.

• NextToken (string) -- If the previous response was incomplete (because there is more data to retrieve), Amazon Lookout for Vision returns a pagination token in the response. You can use this pagination token to retrieve the next set of models.
• MaxResults (integer) -- The maximum number of results to return per paginated call. The largest value you can specify is 100. If you specify a value greater than 100, a ValidationException error occurs. The default value is 100.
