使用

商业模型对于网络安全领域问题大多会有道德限制,所以基于网络安全数据训练了一个模型,模型基于Baichuan 13B,模型参数大小130亿,至少需要30G显存运行,35G最佳。

模型加载

from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
from peft import PeftModel
device = 'auto'
tokenizer = AutoTokenizer.from_pretrained("w8ay/secgpt", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("w8ay/secgpt", 
                                             trust_remote_code=True,
                                             device_map=device,
                                             torch_dtype=torch.float16)
print("模型加载成功")
