以4 比特加载模型的基本方法是通过在调用from_pretrained方法时传递参数load_in_4bit=True,并将设备映射设置成“auto”。 fromtransformersimportAutoModelForCausalLM model = AutoModelForCausalLM.from_pretrained("facebook/opt-350m", load_in_4bit=True, device_map="auto") ... 这样就行了! 一般地,我们...
首先安装trl包并下载脚本: pip install trl gitclonehttps://github.com/lvwerra/trl 然后,你就可以运行脚本了: python trl/examples/scripts/sft_trainer.py \ --model_name meta-llama/Llama-2-7b-hf \ --dataset_name timdettmers/openassistant-guanaco \ --load_in_4bit \ --use_peft \ --batch_...
