As the field of machine learning continues to grow, so does the need for efficient and effective ways to deploy models. One popular option for deploying models is Amazon SageMaker, a fully-managed service that provides developers with the ability to build, train, and deploy machine learning models at scale. Recently, Amazon SageMaker has added support for hosting ONNX models using Triton, a high-performance inference server developed by NVIDIA. In this article, we will explore how to host ONNX models on Amazon SageMaker using Triton with Amazon Web Services.
What is ONNX?
ONNX (Open Neural Network Exchange) is an open-source format for representing deep learning models. It was developed by Microsoft and is now supported by a number of major companies, including Amazon, Facebook, and NVIDIA. ONNX allows developers to train models using one framework and then deploy them using another framework, making it easier to move models between different environments.
What is Triton?
Triton is a high-performance inference server developed by NVIDIA. It provides a flexible and scalable platform for deploying deep learning models in production environments. Triton supports a wide range of frameworks, including TensorFlow, PyTorch, and ONNX.
How to Host ONNX Models on Amazon SageMaker using Triton
To host an ONNX model on Amazon SageMaker using Triton, you will need to follow these steps:
1. Convert your ONNX model to a Triton-compatible format. You can do this using the ONNX-TensorRT converter, which is included in the NVIDIA TensorRT package.
2. Create a Triton model repository. This is where you will store your converted model files.
3. Create a Triton model configuration file. This file specifies the details of your model, such as the input and output shapes and data types.
4. Create a Triton inference server on Amazon SageMaker. You can do this using the AWS Management Console or the AWS CLI.
5. Deploy your Triton model to the inference server. This can be done using the Triton command-line interface (CLI) or the Triton Python API.
6. Test your deployed model. You can do this using the Triton client libraries or by sending HTTP requests to the inference server.
Benefits of Hosting ONNX Models on Amazon SageMaker using Triton
There are several benefits to hosting ONNX models on Amazon SageMaker using Triton:
1. High performance: Triton is designed for high-performance inference, making it ideal for production environments where speed is critical.
2. Flexibility: Triton supports a wide range of frameworks, including ONNX, TensorFlow, and PyTorch, giving developers the flexibility to choose the best framework for their needs.
3. Scalability: Amazon SageMaker provides a scalable platform for hosting models, allowing developers to easily deploy and manage models at scale.
4. Cost-effective: Amazon SageMaker offers a pay-as-you-go pricing model, making it cost-effective for both small and large-scale deployments.
Conclusion
Hosting ONNX models on Amazon SageMaker using Triton is a powerful and flexible way to deploy deep learning models in production environments. With its high-performance inference capabilities, flexibility, scalability, and cost-effectiveness, Triton is an ideal choice for developers looking to deploy models at scale. By following the steps outlined in this article, you can easily get started with hosting ONNX models on Amazon SageMaker using Triton with Amazon Web Services.
