[Example Request] Example to host llama 13b on sagemaker using neurons

https://github.com/aws/amazon-sagemaker-examples-community/blob/main/torchserve/inf2/llama2/llama-2-13b.ipynb

Could create an endpoint as above for llama 13b base, but it gives a timeout error on container primary for 13b chat.

For above, created the neuron artifacts for the 13b chat model using this -
https://github.com/pytorch/serve/blob/master/examples/large_models/inferentia2/llama2/Readme.md?plain=1#L56
Could start torchserve and run inference via curl command here, so the model artifacts look okay. But the same artifacts won't work in the first notebook reference link.

Start with the referenced torchserve/inf2/llama2/llama-2-13b.ipynb and compare it with the PyTorch Serve Inferentia2 Llama 2 README at the cited section. Reproduce the timeout for the 13B chat model, then determine why its neuron artifacts work with TorchServe and curl but not in the SageMaker endpoint. Done means the example hosts the chat model and supports successful inference.
