AWS Deep Learning (DL) Containers now come with libraries and packages required for model training and inference in Amazon SageMaker. Amazon SageMaker is a fully managed service that enables you to build, train, and deploy machine learning models at scale. You can now use DL Containers seamlessly across Amazon SageMaker, Amazon Elastic Container Service for Kubernetes (Amazon EKS), self-managed Kubernetes on Amazon EC2, and Amazon Elastic Container Service (Amazon ECS). This release of DL Containers also updates Apache MXNet images to 1.4.1 with support for CUDA 10.0.
