Change example model to non gated model

[tom-doerr]

When I try to instantiate a model with the example from the documentation (https://dspy-docs.vercel.app/docs/building-blocks/language_models) with

llama = dspy.HFModel(model = 'meta-llama/Llama-2-7b-hf')

I'm getting

Cannot access gated repo for url https://huggingface.co/meta-llama/Llama-2-7b-hf/resolve/main/config.json.
Repo model meta-llama/Llama-2-7b-hf is gated. You must be authenticated to access it.

How about just changing the model to mistralai/Mistral-7B-Instruct-v0.2?
Seems to work without issues.

Makes sense. Thanks @tom-doerr! We'd merge this PR :D

Hi @tom-doerr , will merge the PR to ensure we have examples of accessible, non-gated models :).

However, you can actually pass your HuggingFace token to fix this issue, as mentioned in the documentation. lmk if that helps!
