PyTorch Neuron (“torch-neuronx”) Setup on Ubuntu 20 with DLAMI Pytorch#

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

This section provide links that will assist you to quickly start with a fresh installation of PyTorch Neuron for both Inference and Training.

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: Trn1 web page, Inf2 web page

  • Check for the latest version of the DLAMI Neuron Pytorch 1.13 AMI and copy the AMI name that starts with “Deep Learning AMI Neuron PyTorch 1.13 (Ubuntu 20.04) <latest_date>” from “AMI Name:” section

  • Search for the copied AMI name in the AMI Search , you should see an exact matching AMI with the AMI name in Community AMIs. Select the AMI and use it to launch the instance.

  • When launching a Trn1, please adjust your primary EBS volume size to a minimum of 512GB.

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