环境准备

申请阿里云GPU服务器：

• CentOS 7.6 64
• Anaconda3-2023.07-1-Linux-x86_64
• Python 3.11.5
• GPU NVIDIA A10（显存24 G/1 core）
• CPU 8 vCore/30G

安装部署

1、安装 Anaconda

wget https://repo.anaconda.com/archive/Anaconda3-2023.07-1-Linux-x86_64.sh
sh Anaconda3-2023.07-1-Linux-x86_64.sh

根据提示一路安装即可。

2、安装CUDA

wget https://developer.download.nvidia.com/compute/cuda/11.2.0/local_installers/cuda_11.2.0_460.27.04_linux.run
sh cuda_11.2.0_460.27.04_linux.run

根据提示安装即可

3、安装PyTorch

conda install pytorch torchvision pytorch-cuda=11.8 -c pytorch -c nvidia

如提示找不到conda命令，需配置Anaconda环境变量。

4、安装 ChatGLM2-6B

mkdir ChatGLM
cd ChatGLM
git clone https://github.com/THUDM/ChatGLM2-6B.git
cd ChatGLM2-6B
pip install -r requirements.txt

加载模型，需要从网上下载模型的7个分片文件，总共大约10几个G大小，可提前下载。

模型下载地址：https://huggingface.co/THUDM/chatglm2-6b/tree/main

微调实践

1、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，放在目录 ChatGLM2-6B/ptuning/myDataset/ 下面。

训练集文件： train_file.json
测试集文件： val_file.json

2、安装python依赖

后面微调训练，需要依赖一些 Python 模块，提前安装一下：

conda install rouge_chinese nltk jieba datasets

3、微调并训练新模型

修改 train.sh 脚本文件，根据自己实际情况配置即可，修改后的配置为：

PRE_SEQ_LEN=128
LR=2e-2
NUM_GPUS=1torchrun --standalone --nnodes=1 --nproc-per-node=$NUM_GPUS main.py \--do_train \--train_file myDataset/train_file.json \--validation_file myDataset/val_file.json \--preprocessing_num_workers 6 \--prompt_column content \--response_column summary \--overwrite_cache \--model_name_or_path /root/ChatGLM/ChatGLM2-6B-main/zhbr/chatglm2-6b \--output_dir output/zhbr-chatglm2-6b-checkpoint \--overwrite_output_dir \--max_source_length 64 \--max_target_length 128 \--per_device_train_batch_size 6 \--per_device_eval_batch_size 6 \--gradient_accumulation_steps 16 \--predict_with_generate \--max_steps 20 \--logging_steps 5 \--save_steps 5 \--learning_rate $LR \--pre_seq_len $PRE_SEQ_LEN \--quantization_bit 4

修改完即可进行微调：

cd /root/ChatGLM/ChatGLM2-6B/ptuning/
sh train.sh

运行结果如下：

对微调后的模型进行评估验证，修改 evaluate.sh 脚本中的 checkpoint 目录：

PRE_SEQ_LEN=128
CHECKPOINT=zhbr-chatglm2-6b-checkpoint
STEP=20
NUM_GPUS=1torchrun --standalone --nnodes=1 --nproc-per-node=$NUM_GPUS main.py \--do_predict \--validation_file myDataset/train_file.json \--test_file myDataset/val_file.json \--overwrite_cache \--prompt_column content \--response_column summary \--model_name_or_path /root/ChatGLM/ChatGLM2-6B-main/zhbr/chatglm2-6b \--ptuning_checkpoint ./output/$CHECKPOINT/checkpoint-$STEP \--output_dir ./output/$CHECKPOINT \--overwrite_output_dir \--max_source_length 64 \--max_target_length 64 \--per_device_eval_batch_size 1 \--predict_with_generate \--pre_seq_len $PRE_SEQ_LEN \--quantization_bit 4

对微调后的模型进行推理和评估：

/root/ChatGLM/ChatGLM2-6B/ptuning/
sh evaluate.sh

运行结果如下：

方法一：

编写python脚本，加载微调训练后生成的 Checkpoint 路径：

from transformers import AutoConfig, AutoModel, AutoTokenizer
import os
import torch
# 载入Tokenizer
tokenizer = AutoTokenizer.from_pretrained("THUDM/chatglm2-6b", trust_remote_code=True)

print(response)

方法二：

修改ptuning中的web_demo.sh，根据自己实际情况配置：

PRE_SEQ_LEN=128CUDA_VISIBLE_DEVICES=0 python3 web_demo.py \--model_name_or_path /root/ChatGLM/ChatGLM2-6B-main/zhbr/chatglm2-6b \--ptuning_checkpoint output/zhbr-chatglm2-6b-checkpoint/checkpoint-20 \--pre_seq_len $PRE_SEQ_LEN

执行web_demo.sh，访问http://xxx.xxx.xxx.xxx:7860。

微调过程中遇到的问题

报错信息如下：

dataclasses.FrozenInstanceError: cannot assign to field generation_max_length
和
dataclasses.FrozenInstanceError: cannot assign to field generation_num_beams

解决方法：
在main.py文件中注释掉以下代码。
