基于趋动云部署复旦大学MOSS大模型

首先新建项目：

MOSS部署项目，然后选择镜像，直接用官方的镜像就可以。

之后选择数据集：

公开数据集中，MOSS_复旦大学_superx 这个数据集就是了，大小31G多

完成选择后：

点击创建，暂不上传代码。

接着，点击运行代码

然后先选择B1主机即可，便宜一些，安装过程也挺费时间的，等装完了，再换成P1的主机。没有80G显存，这栋西跑不动。

如下图所示，进行设置配置即可

等待，到开发环境运行起来。

点击进入开发环境，在网页终端中，进行命令行操作：

cd /gemini/code/

git config --global url."https://gitclone.com/".insteadOf https://
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
python3 -m pip install --upgrade pip

git clone https://github.com/OpenLMLab/MOSS.git

可以看到路径下MOSS工程已近下载到位了

然后执行以下命令

cd MOSS/

mkdir fnlp

cd fnlp/

ln -s /gemini/data-1/MOSS /gemini/code/MOSS/fnlp/moss-moon-003-sft

ls -lash

达到如下效果，这样我们就把模型挂载到了MOSS web UI的正确路径。

接着进入到MOSS的路径下

cd /gemini/code/MOSS

修改requirements.txt文件，因为平台的torch版本要高，要修改，另外webui需要增加些库

修改torch版本和镜像版本一致 1.12.1

末尾增加2个库，如图所示

mdtex2html

gradio

修改后记得ctrl+s保存。

然后打开文件

修改34行，在行尾增加 , max_memory={0: "70GiB", "cpu": "20GiB"}

意思是显存最大用70G，内存最大用20G

如图所示：

修改第178行

改成这样：

demo.queue().launch(share=True, server_name="0.0.0.0",server_port=19527)

有人反馈说，git下来的工程里，gui不在了，附上全部内容：

接着回到网页终端，执行

pip install -r requirements.txt

一阵滚屏之后，就安装完成了。

至此，安装就全部完成了。开始运行（退出时记得勾选保存镜像，以后进入环境，只需要执行下面的步骤）。安装环节完成。可以退出保存镜像。然后把执行环境调整成P1 80G显存的那个，来跑这个MOSS了。感受大模型的魅力吧！

进入网页终端后，只需要执行：

cd /gemini/code/MOSS

python moss_gui_demo.py

等待模型加载完毕，出现

http://0.0.0.0:19527

的文本信息，就启动完成，可以去访问了。公网访问方法，前两篇都有说过。不再重复了

效果：
