Following are the steps you can use in your Jupyter or AWS Sagemaker notebook or even in Linux instances to run and install Llama 2 on Petals easily.

Prerequisites:

- Subscribe with your email at Meta's website here.

- Login with same email at Hugging face and Submit Request to access the Llama 2 model here.

- Generate Hugging Face Token here.

Then use following commands in order (Make sure to replace your own hugging face token below):

%pip install petals

import torch

from transformers import AutoTokenizer

from petals import AutoDistributedModelForCausalLM

model_name = "meta-llama/Llama-2-70b-hf"

!huggingface-cli login --token <Your huggingface Token>

tokenizer = AutoTokenizer.from_pretrained(model_name, use_fast=False, add_bos_token=False)

model = AutoDistributedModelForCausalLM.from_pretrained(model_name)

model = model.cuda()

I hope this helps.
