describeProjectVersions method
Lists and describes the models in an Amazon Rekognition Custom Labels
project. You can specify up to 10 model versions in
ProjectVersionArns
. If you don't specify a value,
descriptions for all models are returned.
This operation requires permissions to perform the
rekognition:DescribeProjectVersions
action.
May throw ResourceNotFoundException. May throw InvalidPaginationTokenException. May throw InvalidParameterException. May throw AccessDeniedException. May throw InternalServerError. May throw ThrottlingException. May throw ProvisionedThroughputExceededException.
Parameter projectArn
:
The Amazon Resource Name (ARN) of the project that contains the models you
want to describe.
Parameter maxResults
:
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.
Parameter nextToken
:
If the previous response was incomplete (because there is more results to
retrieve), Amazon Rekognition Custom Labels returns a pagination token in
the response. You can use this pagination token to retrieve the next set
of results.
Parameter versionNames
:
A list of model version names that you want to describe. You can add up to
10 model version names to the list. If you don't specify a value, all
model descriptions are returned. A version name is part of a model
(ProjectVersion) 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
.
