Installing linux headers (DLAMI AMI) failed in INF2 installation guide

Question

Hello, i'm using **pytorch-inference:2.0.1-gpu-py310-cu118-ubuntu20.04-sagemaker**  AMI and following this guide https://awsdocs-neuron.readthedocs-hosted.com/en/latest/general/setup/neuron-setup/pytorch/neuronx/ubuntu/torch-neuronx-ubuntu20-base-dlami.html#setup-torch-neuronx-ubuntu20-base-dlami to install tools and drivers. I. get error when i'm trying to install **sudo apt-get install linux-headers-$(uname -r) -y**. The error i get is 
`E: Unable to locate package linux-headers-4.14.326-245.539.amzn2.x86_64
E: Couldn't find any package by glob linux-headers-4.14.326-245.539.amzn2.x86_64
E: Couldn't find any package by regex linux-headers-4.14.326-245.539.amzn2.x86_64`
How can i make it work?

Answer

It looks like you are using the wrong AMI - you should not need to modify the base AMI. Please follow this link https://awsdocs-neuron.readthedocs-hosted.com/en/latest/general/devflows/inference/byoc-hosting-devflow-inf2.html and use a DLC from the 'Neuron Containers' section. These containers are all tested: https://github.com/aws/deep-learning-containers/blob/master/available_images.md#neuron-containers

Note we don't have PyTorch 2.0 support. PyTorch 2.1 support will be available in an upcoming release.
