teardown¶

autogluon.cloud.teardown(*, backend: Literal['sagemaker', 'ray_aws'] | None = None, session: Session | None = None) → None[source]¶

Delete a backend’s CloudFormation stack and remove its config entry.

With backend=None (default), tears down every configured backend and removes the config file. With backend="sagemaker", tears down just that one and leaves any other backends in the config.

The S3 buckets are not emptied for you: CloudFormation refuses to delete a non-empty bucket, so you must remove their contents (e.g. via aws s3 rm s3://<bucket> --recursive) before calling teardown(). This is intentional — buckets may contain training artifacts or model weights that are expensive to recreate.

Parameters:

backend – Which backend to tear down. None (default) tears down all configured backends.
session – A boto3.Session to use for AWS calls. If None, a default session is built from the standard credential chain, with each backend’s saved region applied automatically.
