大模型部署手记（3）通义千问+Windows GPU-编程知识

1.简介

组织机构：阿里

代码仓：GitHub - QwenLM/Qwen: The official repo of Qwen (通义千问) chat & pretrained large language model proposed by Alibaba Cloud.

模型：Qwen/Qwen-7B-Chat-Int4

下载：http://huggingface.co/Qwen/Qwen-7B-Chat-Int4

modelscope下载：https://modelscope.cn/models/qwen/Qwen-7B-Chat-Int4/summary

硬件环境：暗影精灵7Plus

Windows版本：Windows 11家庭中文版 Insider Preview 22H2

内存 32G

GPU显卡：Nvidia GTX 3080 Laptop （16G）

安装阿里的通义千问大模型有两种方式，modelscope方式和transformers（huggingface）方式。

2.代码和模型下载

下载代码仓：

git clone https://github.com/QwenLM/Qwen.git

模型下载参见第四部分执行 python Qwen-7B-Chat-Int4.py的过程。

3.安装依赖

打开Anaconda Powershell Prompt，创建conda环境：

conda create -n model310 python=3.10

conda activate model310

安装modelscope基础库

pip install modelscope

在安装modelscope的时候，系统会自动安装pytorch 2.0.1（后面会发现装的torch这个完全不对）

打开魔搭社区 http://modelscope.cn

注册一下：

打开 Qwen-7B inr4量化的主页：https://modelscope.cn/models/qwen/Qwen-7B-Chat-Int4/summary

安装量化依赖：

pip install auto-gptq optimum

安装量化包：

pip install bitsandbytes --prefer-binary --extra-index-url=https://jllllll.github.io/bitsandbytes-windows-webui

安装其他依赖：

pip install transformers_stream_generator

pip install tiktoken

pip install deepspeed

目前deepspeed在windows上的安装还存在问题。我们先忽略掉吧！

安装flash-attention库

git clone -b v1.0.8 https://github.com/Dao-AILab/flash-attention

cd flash-attention

pip install .

# 下方安装可选，安装可能比较缓慢。

# Below are optional. Installing them might be slow.

# pip install csrc/layer_norm

# pip install csrc/rotary

看日志应该是torch可能不是CUDA的版本。

验证下：

果然如此。

还是使用conda安装pytorch 2.0的CUDA版本吧！

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

为了保险，还是要验证一下：

python

import torch

#pytorch的版本

torch.__version__

#是否支持CUDA

torch.cuda.is_available()

#CUDA的版本

print(torch.version.cuda)

#cuDNN的版本

print(torch.backends.cudnn.version())

#GPU内存

torch.cuda.get_device_capability(device=0)

再来：

pip install .

4.部署验证

编辑d:\Qwen\Qwen-7B-Chat-Int4.py 文件，内容如下：

from modelscope import AutoTokenizer, AutoModelForCausalLM, snapshot_download
model_dir = snapshot_download("qwen/Qwen-7B-Chat-Int4", revision = 'v1.1.3' )# Note: The default behavior now has injection attack prevention off.
tokenizer = AutoTokenizer.from_pretrained(model_dir, trust_remote_code=True)model = AutoModelForCausalLM.from_pretrained(model_dir,device_map="auto",trust_remote_code=True
).eval()
response, history = model.chat(tokenizer, "你好", history=None)
print(response)
# 你好！很高兴为你提供帮助。

执行这个文件：

cd d:\Qwen

python Qwen-7B-Chat-Int4.py

pip install chardet

再来：

python Qwen-7B-Chat-Int4.py

耐心等待模型下载完毕。。。

看来模型是下载到了这个目录：C:\Users\用户名\.cache\modelscope\hub\qwen\Qwen-7B-Chat-Int4

这个下载的时候不显示速度，下载完毕之后才显示速度。。。

仔细看看还少装了什么包：

pip install cchardet

再来：

python Qwen-7B-Chat-Int4.py

看来已经能成功运行了。

将前面下载目录 C:\Users\用户名\.cache\modelscope\hub\qwen\Qwen-7B-Chat-Int4 下的所有文件复制到当前目录的 Qwen\Qwen-7B-Chat-Int4 目录:

修改cli_demo.py

修改如下代码：

DEFAULT_CKPT_PATH = './Qwen/Qwen-7B-Chat-Int4'

运行 python cli_demo.py

系统很快会弹出：

做一些交互：

不过每次都要清屏，有点不舒服。

把代码中的clear_screen都去掉：（除了收到明确的clear命令）

CTRL-C退出去重新运行：python cli_demo.py

貌似有点问题，代码好像每次都在做刷屏，然后输入一行新的话处理。

经过多次尝试，代码这样修改就可以了：
