Moss量化模型部署记录

一、Moss仓库代码下载及环境准备

  • 下载本仓库内容至本地/远程服务器
git clone https://github.com/OpenLMLab/MOSS.git 
  • 安装依赖
cd MOSS
pip install -r requirements.txt
  • 使用量化模型,需要安装triton
pip install triton

注意:使用triton可能会出现triton not installed报错,如果确认已经安装过triton,可以从仓库中将下载的custom_autotune.py文件放到huggingface modules对应的文件夹中,进入仓库目录,执行:

cp custom_autotune.py ~/.cache/huggingface/modules/transformers_modules/local/

二、下载对应的Moss模型模型

我下载的模型是moss-moon-003-sft-int8。
其他Moss当前所有模型介绍及下载可参考如下地址(github中也有对应的地址链接):https://huggingface.co/fnlp

模型介绍

  • moss-moon-003-base: MOSS-003基座模型,在高质量中英文语料上自监督预训练得到,预训练语料包含约700B单词,计算量约6.67x1022次浮点数运算。
  • moss-moon-003-sft: 基座模型在约110万多轮对话数据上微调得到,具有指令遵循能力、多轮对话能力、规避有害请求能力。
  • moss-moon-003-sft-plugin: 基座模型在约110万多轮对话数据和约30万插件增强的多轮对话数据上微调得到,在moss-moon-003-sft基础上还具备使用搜索引擎、文生图、计算器、解方程等四种插件的能力。
  • moss-moon-003-sft-int4: 4bit量化版本的moss-moon-003-sft模型,约占用12GB显存即可进行推理。
  • moss-moon-003-sft-int8: 8bit量化版本的moss-moon-003-sft模型,约占用24GB显存即可进行推理。
  • moss-moon-003-sft-plugin-int4: 4bit量化版本的moss-moon-003-sft-plugin模型,约占用12GB显存即可进行推理。
  • moss-moon-003-pm: 在基于moss-moon-003-sft收集到的偏好反馈数据上训练得到的偏好模型,将在近期开源。
  • moss-moon-003: 在moss-moon-003-sft基础上经过偏好模型moss-moon-003-pm训练得到的最终模型,具备更好的事实性和安全性以及更稳定的回复质量,将在近期开源。
  • moss-moon-003-plugin: 在moss-moon-003-sft-plugin基础上经过偏好模型moss-moon-003-pm训练得到的最终模型,具备更强的意图理解能力和插件使用能力,将在近期开源。

git lfs install
git clone https://huggingface.co/fnlp/moss-moon-003-sft

如果提示git lfs未安装相关内容,可使用如下方法进行安装:
windows:

	1. 下载安装 windows installer
	2. 运行 windows installer
	3. git lfs install

mac:

安装 homebrew
brew install git-lfs
git lfs install

linux:

Centos
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.rpm.sh | sudo bash
sudo yum install git-lfs
git lfs install

Ubuntu
curl -s https://packagecloud.io/install/repositories/github/git-lfs/script.deb.sh | sudo bash
sudo apt-get install git-lfs
git lfs install

三、开始部署模型

(一)终端交互cli部署记录

我是在autodl平台尝试部署运行模型的,机器配置如下:

镜像
PyTorch 2.0.0
Python 3.8(ubuntu20.04)
Cuda 11.8
GPU
V100-32GB(32GB) * 1
CPU10 vCPU Intel Xeon Processor (Skylake, IBRS)
内存 72GB

在autodl平台上完成以上两个步骤的模型下载和仓库代码下载后,找到仓库所在目录,修改脚本。
1.修改代码仓库中moss_cli_demo.py脚本:
Moss量化模型部署记录_第2张图片
Moss量化模型部署记录_第3张图片
新增语句为:

model = MossForCausalLM.from_pretrained("/root/moss-moon-003-sft-int8", trust_remote_code=True).half().cuda()

修改完成后运行moss_cli_demo.py脚本:

python moss_cli_demo.py

运行结果如下:

占用资源情况如下:

推理响应时间在10s-90s之间不等,主要根据返回的内容长度有所变化。
(PS:其实感觉挺慢的,不知道是不是机器配置原因。)

(二)webui部署记录

在autodl平台上完成以上两个步骤的模型下载和仓库代码下载后,找到仓库所在目录,修改脚本。
因为我想跑的是webui Demo,所以,按照github提示,先安装gradio:

pip install gradio

(注:后来运行启动过程中又出现mdtex2html的报错,又使用pip install mdtex2html命令安装了mdtex2html)

之后修改moss_gui_demo.py脚本,修改位置如图:
Moss量化模型部署记录_第6张图片

moss_gui_demo.py修改后的代码如下:

from accelerate import init_empty_weights, load_checkpoint_and_dispatch

from huggingface_hub import snapshot_download

try:
    from transformers import MossForCausalLM, MossTokenizer
except (ImportError, ModuleNotFoundError):
    from models.modeling_moss import MossForCausalLM
    from models.tokenization_moss import MossTokenizer
    from models.configuration_moss import MossConfig

logger.setLevel("ERROR")
warnings.filterwarnings("ignore")

model_path = "/root/moss-moon-003-sft-int8"

if not os.path.exists(model_path):
    model_path = snapshot_download(model_path)

print("Waiting for all devices to be ready, it may take a few minutes...")
config = MossConfig.from_pretrained(model_path)
tokenizer = MossTokenizer.from_pretrained(model_path)

with init_empty_weights():
    raw_model = MossForCausalLM._from_config(config, torch_dtype=torch.float16)
raw_model.tie_weights()
#model = load_checkpoint_and_dispatch(
#    raw_model, model_path, device_map="auto", no_split_module_classes=["MossBlock"], dtype=torch.float16
#)
model = MossForCausalLM.from_pretrained(model_path).half().cuda()
