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qwen14b，模型参数大小140亿，至少需要30G显存运行，35G最佳。

- peft
模型加载
from transformers import AutoModelForCausalLM, AutoTokenizer
import torch
from peft import PeftModel
device = 'auto'
tokenizer = AutoTokenizer.from_pretrained("w8ay/secgpt1_5", trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained("w8ay/secgpt1_5",
trust_remote_code=True,
device_map=device,
torch_dtype=torch.float16)
print("模型加载成功")
