ChatGLM2-6B微调实践-Lora方案
环境部署
安装Anaconda、CUDA、PyTorch
Lora微调
项目部署
bash
git clone https://github.com/shuxueslpi/chatGLM-6B-QLoRA.git
cd chatGLM-6B-QLoRA
pip install -r requirements.txt准备数据集
准备我们自己的数据集，分别生成训练文件和测试文件这两个文件，放在项目data文件夹，数据格式为：
bash
{
"instruction": "类型#裤*版型#宽松*风格#性感*图案#线条*裤型#阔腿裤",
"output": "宽松的阔腿裤这两年真的吸粉不少，明星时尚达人的心头爱。毕竟好穿时尚，谁都能穿出腿长2米的效果宽松的裤腿，当然是遮肉小能手啊。上身随性自然不拘束，面料亲肤舒适贴身体验感棒棒哒。系带部分增加设计看点，还让单品的设计感更强。腿部线条若隐若现的，性感撩人。颜色敲温柔的，与裤子本身所呈现的风格有点反差萌。"
}训练集文件： train.json
测试集文件： dev.json
修改训练脚本
创建train_qlora.sh，添加以下命令：
bash
python3 train_qlora.py \
--train_args_json chatGLM_6B_QLoRA.json \
--model_name_or_path THUDM/chatglm-6b \
--train_data_path data/train.json \
--eval_data_path data/dev.json \
--lora_rank 4 \
--lora_dropout 0.05 \
--compute_dtype fp32修改model_name_or_path参数为本地真实的模型路径。
chatGLM_6B_QLoRA.json文件为所有transformers框架支持的TrainingArguments，可根据实际情况自行修改。参考：https://huggingface.co/docs/transformers/main_classes/trainer#transformers.TrainingArguments
执行脚本训练，训练过程如下：
bash
(base) [root@iZbp178u8rw9n9ko94ubbyZ chatGLM-6B-QLoRA-main]# sh train_qlora.sh

adapter推理
创建test.py脚本，添加以下代码：
bash
import torch
from transformers import AutoModel, AutoTokenizer, BitsAndBytesConfig
from peft import PeftModel, PeftConfig
peft_model_path = 'saved_files/chatGLM_6B_QLoRA_t32'
config = PeftConfig.from_pretrained(peft_model_path)
q_config = BitsAndBytesConfig(load_in_4bit=True,
bnb_4bit_quant_type='nf4',
bnb_4bit_use_double_quant=True,
bnb_4bit_compute_dtype=torch.float32)
base_model = AutoModel.from_pretrained(config.base_model_name_or_path,
quantization_config=q_config,
trust_remote_code=True,
device_map='auto')
input_text = '配网故障故障评价的指标是什么'
print(f'输入：\n{input_text}')
tokenizer = AutoTokenizer.from_pretrained(config.base_model_name_or_path, trust_remote_code=True)
response, history = base_model.chat(tokenizer=tokenizer, query=input_text)
print(f'微调前：\n{response}')
model = PeftModel.from_pretrained(base_model, peft_model_path)
response, history = model.chat(tokenizer=tokenizer, query=input_text)
print(f'微调后: \n{response}')推理结果如下：
通过对比微调前和微调后的回答结果，可见微调后的回答更贴近数据集的内容：
模型微调达到了预期目标。
模型合并与量化
合并微调的Lora model和基座base model。
使用的项目目前使用的peft为dev的版本，在合并lora model和base model时，会报错。项目推荐将peft的版本回退到0.3.0。
bash
pip install peft==0.3.0创建merge_lora_and_quantize.sh脚本，添加如下命令：
bash
python3 merge_lora_and_quantize.py \
--lora_path saved_files/chatGLM_6B_QLoRA_t32 \
--output_path /tmp/merged_qlora_model_4bit \
--remote_scripts_dir /root/ChatGLM/ChatGLM2-6B-main/zhbr/chatglm2-6b \
--qbits 4remote_scripts_dir 为ChatGLM2的本地地址
qbits 量化为4bit
执行脚本，运行结果如下：
bash
(base) [root@iZbp178u8rw9n9ko94ubbyZ chatGLM-6B-QLoRA-main]# sh merge_lora_and_quantize.sh

2023-10-10 10:39:59.215 | INFO | __main__:main:58 - Lora model和base model成功merge, 并量化为4bits, 保存在/tmp/merged_qlora_model_4bit模型合并的如下所示：
合并后的模型推理
创建test2.py，添加如下代码：

response, history = model.chat(tokenizer=tokenizer, query=input_text)
print(response)推理结果如下，贴合训练数据集的内容：
测试lora微调后是否会产生灾难性遗忘问题：
1、以李白的风格写一首描述秋天的七言律诗：
2、开车过程如何减少燃油消耗
测试没有出现类似P-Tuning微调出现的严重遗忘问题。
微调过程中遇到的问题
1、出现wandb让选择W&B Account
解决方法：
1、执行wandb off，关掉即可
2、在train_qlora.py开头配置环境变量：
os.environ["WANDB_DISABLED"] = "true"
2、微调后saved_files中只有adapter_config.json和adapter_model.bin两个文件，没有checkpoint：
正常训练完不只这两个文件，还会有多个checkpoints。原因是训练的步数太少，连保存checkpoint的step都没有达到。
解决方法：
适当调整chatGLM_6B_QLoRA.json中的配置
