【浦语开源】深入探索:大模型全链路开源组件 InternLM & Lagent,打造灵笔Demo实战指南

发布于:2024-06-30 ⋅ 阅读:(50) ⋅ 点赞:(0)

一、准备工作:

1、环境配置:

pip、conda换源:

pip临时换源:

pip install -i https://mirrors.cernet.edu.cn/pypi/web/simple some-package

# 这里的“https://mirrors.cernet.edu.cn/pypi/web/simple”是所换的源,“some-package”是你需要安装的包

设置pip默认源,避免每次下载依赖包都要加上一长串的国内源

pip config set global.index-url https://mirrors.cernet.edu.cn/pypi/web/simple

conda换源:

镜像站提供了 Anaconda 仓库与第三方源(conda-forge、msys2、pytorch 等),各系统都可以通过修改用户目录下的
.condarc
文件来使用镜像站。

不同系统下的
.condarc
目录如下:

  • Linux
    :
    ${HOME}/.condarc
  • macOS
    :
    ${HOME}/.condarc
  • Windows
    :
    C:\Users\<YourUserName>\.condarc

注意:

  • Windows
    用户无法直接创建名为
    .condarc
    的文件,可先执行
    conda config --set show_channel_urls yes
    生成该文件之后再修改。
cat <<'EOF' > ~/.condarc
channels:
  - defaults
show_channel_urls: true
default_channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/r
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/msys2
custom_channels:
  conda-forge: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud
  pytorch: https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud

2、模型下载:

Huggingface:

使用 Hugging Face 官方提供的
huggingface-cli
命令行工具。安装依赖:

pip install -U huggingface_hub

安装好依赖包之后,执行以下代码:

import os
from huggingface_hub import hf_hub_download  # Load model directly 

# 下载模型
os.system('huggingface-cli download --resume-download internlm/internlm-chat-7b --local-dir your_path')

# resume-download:断点续下(断网也可继续下载)
# local-dir:本地存储路径。(linux 环境下需要填写绝对路径)

hf_hub_download(repo_id="internlm/internlm-7b", filename="config.json")

# repo_id: 模型的名称
# filename: 下载的文件名称

ModelScope:

安装依赖:

pip install modelscope==1.9.5
pip install transformers==4.35.2

安装完成后:

import torch
from modelscope import snapshot_download, AutoModel, AutoTokenizer
import os
model_dir = snapshot_download('Shanghai_AI_Laboratory/internlm-chat-7b', cache_dir='your path', revision='master')

# cache_dir:最好写成绝对路径

OpenXLAB:

安装依赖:

pip install -U openxlab

执行代码:

from openxlab.model import download
download(model_repo='OpenLMLab/InternLM-7b', model_name='InternLM-7b', output='your local path')

二、InternLM智能对话 Demo:

1、准备硬件设备:显卡

目前显卡比较短缺,各位大佬各显神通吧,这里以
InternStudio
为例

2、进入开发机配置环境:

进入
conda
环境之后,使用以下命令从本地克隆一个已有的
pytorch 2.0.1
的环境,运行时间可能比较长,耐心等待

bash # 请每次使用 jupyter lab 打开终端时务必先执行 bash 命令进入 bash 中
conda create --name internlm-demo --clone=/root/share/conda_envs/internlm-base

然后用下面命令激活虚拟环境,并安装所需环境:

conda activate internlm-demo


————————————————————————————demo所需的环境依赖
# 升级pip
python -m pip install --upgrade pip

pip install modelscope==1.9.5
pip install transformers==4.35.2
pip install streamlit==1.24.0
pip install sentencepiece==0.1.99
pip install accelerate==0.24.1

3、模型下载:

根据之前介绍的模型下载的三种方式都可以实现模型的下载,但是速度相对较慢,这里我使用的是
InternStudio
平台的
share
目录下已经为我们准备好的
InternLM
模型。

mkdir -p /root/model/Shanghai_AI_Laboratory
cp -r /root/share/temp/model_repos/internlm-chat-7b /root/model/Shanghai_AI_Laboratory

4、代码准备:


/root
路径下新建
code
目录,然后切换路径, clone 代码

cd /root/code
git clone https://gitee.com/internlm/InternLM.git


## 切换 commit 版本,可以让大家更好的复现
cd InternLM
git checkout 3028f07cb79e5b1d7342f4ad8d11efad3fd13d17


/root/code/InternLM/web_demo.py
中 29 行和 33 行的模型更换为本地的
/root/model/Shanghai_AI_Laboratory/internlm-chat-7b

5、运行:

(1)终端运行:


/root/code/InternLM
目录下新建一个
cli_demo.py
文件,将以下代码填入其中:

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM


model_name_or_path = "/root/model/Shanghai_AI_Laboratory/internlm-chat-7b"

tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, trust_remote_code=True)
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, trust_remote_code=True, torch_dtype=torch.bfloat16, device_map='auto')
model = model.eval()

system_prompt = """You are an AI assistant whose name is InternLM (书生·浦语).
- InternLM (书生·浦语) is a conversational language model that is developed by Shanghai AI Laboratory (上海人工智能实验室). It is designed to be helpful, honest, and harmless.
- InternLM (书生·浦语) can understand and communicate fluently in the language chosen by the user such as English and 中文.
"""

messages = [(system_prompt, '')]

print("=============Welcome to InternLM chatbot, type 'exit' to exit.=============")

while True:
    input_text = input("User  >>> ")
    input_text = input_text.replace(' ', '')
    if input_text == "exit":
        break
    response, history = model.chat(tokenizer, input_text, history=messages)
    messages.append((input_text, response))
    print(f"robot >>> {response}")

然后在终端运行:python /root/code/InternLM/cli_demo.py  即可

(2)web运行:

运行
/root/code/InternLM
目录下的
web_demo.py
文件,输入以下命令后,l利用SSH密钥将端口映射到本地。在本地浏览器输入
http://127.0.0.1:6006
即可。

bash
conda activate internlm-demo  # 首次进入 vscode 会默认是 base 环境,所以首先切换环境
cd /root/code/InternLM
streamlit run web_demo.py --server.address 127.0.0.1 --server.port 6006

三、Lagent智能工具demo调用:

1、环境准备:

Lagent所需环境和InternLM环境一直,若运行环境已经安装好依赖包可直接跳过:

# 升级pip
python -m pip install --upgrade pip

pip install modelscope==1.9.5
pip install transformers==4.35.2
pip install streamlit==1.24.0
pip install sentencepiece==0.1.99
pip install accelerate==0.24.1

2、模型下载:

Lagnet是智能体构建的工具,基础模型可以直接使用InterLM模型,无需重复下载。

3、代码准备:

切换路径到
/root/code
克隆
lagent
仓库,并通过
pip install -e .
源码安装
Lagent

cd /root/code
git clone https://gitee.com/internlm/lagent.git
cd /root/code/lagent
git checkout 511b03889010c4811b1701abb153e02b8e94fb5e # 尽量保证和教程commit版本一致
pip install -e . # 源码安装


/root/code/lagent/examples/react_web_demo.py

            with open(file_path, 'wb') as tmpfile:
                tmpfile.write(file_bytes)
            st.write(f'File saved at: {file_path}')
            user_input = '我上传了一个图像,路径为: {file_path}. {user_input}'.format(
                file_path=file_path, user_input=user_input)
        agent_return = st.session_state['chatbot'].chat(user_input)
        st.session_state['assistant'].append(copy.deepcopy(agent_return))
        logger.info(agent_return.inner_steps)
        st.session_state['ui'].render_assistant(agent_return)


if __name__ == '__main__':
    root_dir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
    root_dir = os.path.join(root_dir, 'tmp_dir')
    os.makedirs(root_dir, exist_ok=True)
    main()

4、web demo运行:

同样,建立ssh远程连接,在浏览器输入
http://127.0.0.1:6006
即可。

streamlit run /root/code/lagent/examples/react_web_demo.py --server.address 127.0.0.1 --server.port 6006

确实厉害,连MBA的题目都能轻松应对。

四、浦语·灵笔图文理解创作 Demo:

1、基础配置:

和之前两个demo一样的流程,从环境配置到模型下载

# 进入 conda 环境之后,使用以下命令从本地克隆一个已有的pytorch 2.0.1 的环境
conda create --name xcomposer-demo --clone=/root/share/conda_envs/internlm-base


# 激活环境
conda activate xcomposer-demo



#安装依赖:
pip install transformers==4.33.1 
pip install timm==0.4.12 
pip install sentencepiece==0.1.99 
pip install gradio==3.44.4 
pip install markdown2==2.4.10 
pip install xlsxwriter==3.1.2 
pip install einops accelerate


# 模型下载:
mkdir -p /root/model/Shanghai_AI_Laboratory
cp -r /root/share/temp/model_repos/internlm-xcomposer-7b /root/model/Shanghai_AI_Laboratory

2、代码准备:

又是老朋友了

cd /root/code
git clone https://gitee.com/internlm/InternLM-XComposer.git
cd /root/code/InternLM-XComposer
git checkout 3e8c79051a1356b9c388a6447867355c0634932d  # 最好保证和教程的 commit 版本一致

3、运行web demo:

终端运行以下代码,同样是在完成ssh连接之后:

cd /root/code/InternLM-XComposer
python examples/web_demo.py  \
    --folder /root/model/Shanghai_AI_Laboratory/internlm-xcomposer-7b \
    --num_gpus 1 \
    --port 6006

num_gpus 指的是使用gpu的数量,vgpu-smi可以查看gpu的使用情况

五、SSH远程服务连接:

这里只是简单的介绍以下本次demo调用中使用的demo配置,具体可以看博客:
ssh用法及命令_ssh命令大全-CSDN博客

1、在本地机器上打开
Power Shell
终端。在终端中,运行以下命令来生成 SSH 密钥对:

ssh-keygen -t rsa

##-t表示类型选项,这里采用rsa加密算法

2、按
Enter
键接受默认值或输入自定义路径 ,默认情况下是在
~/.ssh/
目录中。(其中有一个提示是要求设置私钥口令passphrase,不设置则为空,这里看心情吧,如果不放心私钥的安全可以设置一下)执行结束以后会在
/home/当前用户 目录下
生成一个
.ssh 文件夹
,其中包含
私钥文件 id_rsa

公钥文件 id_rsa.pub

3、通过系统自带的
cat
工具查看文件内容:

cat ~\.ssh\id_rsa.pub
# ~ 是用户主目录的简写,.ssh 是SSH配置文件的默认存储目录,id_rsa.pub 是 SSH 公钥文件的默认名称。所以,cat ~\.ssh\id_rsa.pub 的意思是查看用户主目录下的 .ssh 目录中的 id_rsa.pub 文件的内容。

4、将公钥复制到剪贴板中,然后回到
InternStudio
控制台,点击配置 SSH Key。

在本

ssh -CNg -L 6006:127.0.0.1:6006 root@ssh.intern-ai.org.cn -p 33090

地终端输入以下指令
.6006
是在服务器中打开的端口,而
33090
是根据开发机的端口进行更改

注意:再这些操作中可能会出现多次warning,个人经验是只要没报错就继续运行。
