[SOLVED] OSError: meta-llama/Llama-2-7b-chat-hf is not a local folder

OSError: meta-llama/Llama-2-7b-chat-hf is not a local folder

I'm trying to replied the code from this Hugging Face blog. At first I installed the transformers and created a token to login to hugging face hub:

pip install transformers
huggingface-cli login

After that it is said to use use_auth_token=True when you have set a token. Unfortunately after running the code I get an error:

from transformers import AutoTokenizer
import transformers
import torch

model = "meta-llama/Llama-2-7b-chat-hf"

tokenizer = AutoTokenizer.from_pretrained(model, use_auth_token=True)
pipeline = transformers.pipeline(
    "text-generation",
    model=model,
    torch_dtype=torch.float16,
    device_map="auto",
)

sequences = pipeline(
    'I liked "Breaking Bad" and "Band of Brothers". Do you have any recommendations of other shows I might like?\n',
    do_sample=True,
    top_k=10,
    num_return_sequences=1,
    eos_token_id=tokenizer.eos_token_id,
    max_length=200,
)
for seq in sequences:
    print(f"Result: {seq['generated_text']}")

Error:

OSError: meta-llama/Llama-2-7b-chat-hf is not a local folder and is not a valid model identifier listed on 'https://huggingface.co/models'
If this is a private repository, make sure to pass a token having permission to this repo with `use_auth_token` or log in with `huggingface-cli login` and pass `use_auth_token=True`.

It says that the model cannot be found, but you can find it in the list of models on hugging face here.

This is the version of the transformers package I'm using:

> pip show transformers

Does anyone know how to fix this error?

Solution

def from_pretrained(cls, pretrained_model_name_or_path, *inputs, **kwargs):

the pretrained_model_name_or_path may the model repo or the model path

in your case the model repo is "meta-llama/Llama-2-7b-chat-hf" which is right.

according to https://huggingface.co/meta-llama/Llama-2-7b-chat-hf/tree/main

you must agree to the terms and conditions in the above link in order to access the model.
