## If I try to delete a SageMaker AI project created from a SageMaker AI template and receive an error due to non-empty Amazon S3 buckets or Amazon ECR repositories, how can I delete the project?

If you try to delete your SageMaker AI project and get one of the following error messages:

```
The bucket you tried to delete is not empty
```

```
The repository with name 'repository-name' in registry 
        with id 'id' cannot be deleted because it still contains images
```

then you have non-empty Amazon S3 buckets or Amazon ECR repositories which you need to manually delete before you delete the SageMaker AI project. CloudFormation does not automatically delete non-empty Amazon S3 buckets or Amazon ECR repositories for you.
