我看了一下, 似乎新版的 transformer 可以直接进行量化后使用, 不需要 额外的量化过程?

model_id = "meta-llama/Llama-2-13b-chat-hf"

nf4_config = BitsAndBytesConfig(load_in_4bit=True,
                                bnb_4bit_quant_type="nf4",
                                bnb_4bit_use_double_quant=True,
                                bnb_4bit_compute_dtype=torch.bfloat16)


model_nf4 = AutoModelForCausalLM.from_pretrained(model_id, 
                                                 quantization_config=nf4_config)
