Cannot load google/gemma-7b

transformers version: 4.39.2

from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("google/gemma-7b")
model = AutoModelForCausalLM.from_pretrained("google/gemma-7b")

on my end, i can load gemma-2b, but for 7b, it returns the error.
even I try to delete the local cache, it still does not work.

rm -r ~/.cache/huggingface/hub/models–google–gemma-7b

May I know the reason ?
thanks.
