Using Llama 2 With Bumblebee

I am trying to use Meta’s Llama 2 with Bumblebee, but I am getting a 401 error when I try to load it. I have been granted access to the repo on Hugging Face, but I think I need to provide an access token when loading the model, and I am not sure how to do so.

{:ok, model} = Bumblebee.load_model({:hf, "meta-llama/Llama-2-7b-chat-hf"})
{:ok, tokenizer} = Bumblebee.load_tokenizer({:hf, "meta-llama/Llama-2-7b-chat-hf"})

** (MatchError) no match of right hand side value: {:error, "HTTP request failed with status 401"}
