PyTorch Neuron (“torch-neuron”) Setup on Amazon Linux 2#

Note

Please make sure to upgrade from python 3.7 to python 3.8 to use Neuron SDK on Amazon Linux 2. Starting from Neuron Release 2.13, python 3.7 is no longer supported as mentioned here. Also, we do not have support for torch-neuronx 2.1.2 on Amaznon Linux 2.

Get Started with Latest Release of PyTorch Neuron (torch-neuron)#

This section provide links that will assist you to quickly start with a fresh installation of PyTorch Neuron (torch-neuron) Setup for Inference.

Launch the Instance

  • Please follow the instructions at launch an Amazon EC2 Instance to launch an instance. When choosing the instance type at the EC2 console, please make sure to select the correct instance type.

  • To get more information about instances sizes and pricing see: Inf1 web page

  • Select Amazon Linux 2 AMI(HVM) - Kernel 5.10

  • After launching the instance, follow the instructions in Connect to your instance to connect to the instance
