Starting with the AWS Neuron 2.18 release, you can now launch Neuron DLAMIs (AWS Deep Learning AMIs) and Neuron DLCs (AWS Deep Learning Containers) with the latest released Neuron packages on the same day as the Neuron SDK release. When a Neuron SDK is released, youll now be notified of the support for Neuron DLAMIs and Neuron DLCs in the Neuron SDK release notes, with a link to the AWS documentation containing the DLAMI and DLC release notes. In addition, this release introduces a number of features that help improve user experience for Neuron DLAMIs and DLCs. In this post, we walk through some of the support highlights with Neuron 2.18.

The DLAMI is a pre-configured AMI that comes with popular deep learning frameworks like TensorFlow, PyTorch, Apache MXNet, and others pre-installed. This allows machine learning (ML) practitioners to rapidly launch an Amazon Elastic Compute Cloud (Amazon EC2) instance with a ready-to-use deep learning environment, without having to spend time manually installing and configuring the required packages. The DLAMI supports various instance types, including Neuron Trainium and Inferentia powered instances, for accelerated training and inference.

AWS DLCs provide a set of Docker images that are pre-installed with deep learning frameworks. The containers are optimized for performance and available in Amazon Elastic Container Registry (Amazon ECR). DLCs make it straightforward to deploy custom ML environments in a containerized manner, while taking advantage of the portability and reproducibility benefits of containers.

The Neuron Multi-Framework DLAMI for Ubuntu 22 provides separate virtual environments for multiple ML frameworks: PyTorch 2.1, PyTorch 1.13, Transformers NeuronX, and TensorFlow 2.10. DLAMI offers you the convenience of having all these popular frameworks readily available in a single AMI, simplifying their setup and reducing the need for multiple installations.

This new Neuron Multi-Framework DLAMI is now the default choice when launching Neuron instances for Ubuntu through the AWS Management Console, making it even faster for you to get started with the latest Neuron capabilities right from the Quick Start AMI list.

The existing Neuron DLAMIs for PyTorch 1.13 and TensorFlow 2.10 have been updated with the latest 2.18 Neuron SDK, making sure you have access to the latest performance optimizations and features for both Ubuntu 20 and Amazon Linux 2 distributions.

Neuron 2.18 also introduces support in Parameter Store, a capability of AWS Systems Manager, for Neuron DLAMIs, allowing you to effortlessly find and query the DLAMI ID with the latest Neuron SDK release. This feature streamlines the process of launching new instances with the most up-to-date Neuron SDK, enabling you to automate your deployment workflows and make sure youre always using the latest optimizations.

To provide customers with more deployment options, Neuron DLCs are now hosted both in the public Neuron ECR repository and as private images. Public images provide seamless integration with AWS ML deployment services such as Amazon EC2, Amazon Elastic Container Service (Amazon ECS), and Amazon Elastic Kubernetes Service (Amazon EKS); private images are required when using Neuron DLCs with Amazon SageMaker.

Prior to this release, Dockerfiles for Neuron DLCs were located within the AWS/Deep Learning Containers repository. Moving forward, Neuron containers can be found in the AWS-Neuron/ Deep Learning Containers repository.

The Neuron SDK documentation and AWS documentation sections for DLAMI and DLC now have up-to-date user guides about Neuron. The Neuron SDK documentation also includes a dedicated DLAMI section with guides on discovering, installing, and upgrading Neuron DLAMIs, along with links to release notes in AWS documentation.

AWS Trainium and AWS Inferentia are custom ML chips designed by AWS to accelerate deep learning workloads in the cloud.

You can choose your desired Neuron DLAMI when launching Trn and Inf instances through the console or infrastructure automation tools like AWS Command Line Interface (AWS CLI). After a Trn or Inf instance is launched with the selected DLAMI, you can activate the virtual environment corresponding to your chosen framework and begin using the Neuron SDK. If youre interested in using DLCs, refer to the DLC documentation section in the Neuron SDK documentation or the DLC release notes section in the AWS documentation to find the list of Neuron DLCs with the latest Neuron SDK release. Each DLC in the list includes a link to the corresponding container image in the Neuron container registry. After choosing a specific DLC, please refer to the DLC walkthrough in the next section to learn how to launch scalable training and inference workloads using AWS services like Kubernetes (Amazon EKS), Amazon ECS, Amazon EC2, and SageMaker. The following sections contain walkthroughs for both the Neuron DLC and DLAMI.

In this section, we provide resources to help you use containers for your accelerated deep learning model acceleration on top of AWS Inferentia and Trainium enabled instances.

The section is organized based on the target deployment environment and use case. In most cases, it is recommended to use a preconfigured DLC from AWS. Each DLC is preconfigured to have all the Neuron components installed and is specific to the chosen ML framework.

The PyTorch Neuron DLC images are published to ECR Public Gallery, which is the recommended URL to use for most cases. If youre working within SageMaker, use the Amazon ECR URL instead of the Amazon ECR Public Gallery. TensorFlow DLCs are not updated with the latest release. For earlier releases, refer to Neuron Containers. In the following sections, we provide the recommended steps for running an inference or training job in Neuron DLCs.

Prepare your infrastructure (Amazon EKS, Amazon ECS, Amazon EC2, and SageMaker) with AWS Inferentia or Trainium instances as worker nodes, making sure they have the necessary roles attached for Amazon ECR read access to retrieve container images from Amazon ECR: arn:aws:iam::aws:policy/AmazonEC2ContainerRegistryReadOnly.

When setting up hosts for Amazon EC2 and Amazon ECS, using Deep Learning AMI (DLAMI) is recommended. An Amazon EKS optimized GPU AMI is recommended to use in Amazon EKS.

You also need the ML job scripts ready with a command to invoke them. In the following steps, we use a single file, train.py, as the ML job script. The command to invoke it is torchrun nproc_per_node=2 nnodes=1 train.py.

Extend the Neuron DLC to include your ML job scripts and other necessary logic. As the simplest example, you can have the following Dockerfile:

This Dockerfile uses the Neuron PyTorch training container as a base and adds your training script, train.py, to the container.

Complete the following steps:

You can now run the extended Neuron DLC in different AWS services.

For Amazon EKS, create a simple pod YAML file to use the extended Neuron DLC. For example:

Use kubectl apply -f .yaml to deploy this pod in your Kubernetes cluster.

For Amazon ECS, create a task definition that references your custom Docker image. The following is an example JSON task definition:

This definition sets up a task with the necessary configuration to run your containerized application in Amazon ECS.

For Amazon EC2, you can directly run your Docker container:

For SageMaker, create a model with your container and specify the training job command in the SageMaker SDK:

This section walks through launching an Inf1, Inf2, or Trn1 instance using the Multi-Framework DLAMI in the Quick Start AMI list and getting the latest DLAMI that supports the newest Neuron SDK release easily.

The Neuron DLAMI is a multi-framework DLAMI that supports multiple Neuron frameworks and libraries. Each DLAMI is pre-installed with Neuron drivers and support all Neuron instance types. Each virtual environment that corresponds to a specific Neuron framework or library comes pre-installed with all the Neuron libraries, including the Neuron compiler and Neuron runtime needed for you to get started.

This release introduces a new Multi-Framework DLAMI for Ubuntu 22 that you can use to quickly get started with the latest Neuron SDK on multiple frameworks that Neuron supports as well as Systems Manager (SSM) parameter support for DLAMIs to automate the retrieval of the latest DLAMI ID in cloud automation flows.

For instructions on getting started with the multi-framework DLAMI through the console, refer to Get Started with Neuron on Ubuntu 22 with Neuron Multi-Framework DLAMI. If you want to use the Neuron DLAMI in your cloud automation flows, Neuron also supports SSM parameters to retrieve the latest DLAMI ID.

Complete the following steps:

Activate your desired virtual environment, as shown in the following screenshot.

After you have activated the virtual environment, you can try out one of the tutorials listed in the corresponding framework or library training and inference section.

Neuron DLAMIs support SSM parameters to quickly find Neuron DLAMI IDs. As of this writing, we only support finding the latest DLAMI ID that corresponds to the latest Neuron SDK release with SSM parameter support. In the future releases, we will add support for finding the DLAMI ID using SSM parameters for a specific Neuron release.

You can find the DLAMI that supports the latest Neuron SDK by using the get-parameter command:

For example, to find the latest DLAMI ID for the Multi-Framework DLAMI (Ubuntu 22), you can use the following code:

You can find all available parameters supported in Neuron DLAMIs using the AWS CLI:

You can also view the SSM parameters supported in Neuron through Parameter Store by selecting the neuron service.

You can use the AWS CLI to find the latest DLAMI ID and launch the instance simultaneously. The following code snippet shows an example of launching an Inf2 instance using a multi-framework DLAMI:

You can also use SSM parameters directly in launch templates. You can update your Auto Scaling groups to use new AMI IDs without needing to create new launch templates or new versions of launch templates each time an AMI ID changes.
