A low-level client representing Amazon Lookout for Vision
This is the Amazon Lookout for Vision API Reference. It provides descriptions of actions, data types, common parameters, and common errors.
Amazon Lookout for Vision enables you to find visual defects in industrial products, accurately and at scale. It uses computer vision to identify missing components in an industrial product, damage to vehicles or structures, irregularities in production lines, and even minuscule defects in silicon wafers — or any other physical item where quality is important such as a missing capacitor on printed circuit boards.
import boto3
client = boto3.client('lookoutvision')
These are the available methods:
Check if an operation can be paginated.
Creates a new dataset in an Amazon Lookout for Vision project. CreateDataset can create a training or a test dataset from a valid dataset source (DatasetSource ).
If you want a single dataset project, specify train for the value of DatasetType .
To have a project with separate training and test datasets, call CreateDataset twice. On the first call, specify train for the value of DatasetType . On the second call, specify test for the value of DatasetType .
This operation requires permissions to perform the lookoutvision:CreateDataset operation.

'GroundTruthManifest': {
'S3Object': {
'Bucket': 'string',
'Key': 'string',

)
[REQUIRED]
The name of the project in which you want to create a dataset.
[REQUIRED]
The type of the dataset. Specify train for a training dataset. Specify test for a test dataset.
The location of the manifest file that Amazon Lookout for Vision uses to create the dataset.
If you don't specify DatasetSource , an empty dataset is created and the operation synchronously returns. Later, you can add JSON Lines by calling UpdateDatasetEntries .
If you specify a value for DataSource , the manifest at the S3 location is validated and used to create the dataset. The call to CreateDataset is asynchronous and might take a while to complete. To find out the current status, Check the value of Status returned in a call to DescribeDataset .
Location information for the manifest file.
The S3 bucket location for the manifest file.
The Amazon S3 bucket that contains the manifest.
The name and location of the manifest file withiin the bucket.
The version ID of the bucket.
ClientToken is an idempotency token that ensures a call to CreateDataset completes only once. You choose the value to pass. For example, An issue might prevent you from getting a response from CreateDataset . In this case, safely retry your call to CreateDataset by using the same ClientToken parameter value.
If you don't supply a value for ClientToken , the AWS SDK you are using inserts a value for you. This prevents retries after a network error from making multiple dataset creation requests. You'll need to provide your own value for other use cases.
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 CreateDataset . An idempotency token is active for 8 hours.

Exceptions
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.

ClientToken is an idempotency token that ensures a call to StartModel completes only once. You choose the value to pass. For example, An issue might prevent you from getting a response from StartModel . In this case, safely retry your call to StartModel by using the same ClientToken parameter value.
If you don't supply a value for ClientToken , the AWS SDK you are using inserts a value for you. This prevents retries after a network error from making multiple start requests. You'll need to provide your own value for other use cases.
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 StartModel . An idempotency token is active for 8 hours.
