1 大模型及 InternLM 模型简介

1.1 什么是大模型?

  大模型通常指的是机器学习或人工智能领域中参数数量巨大、拥有庞大计算能力和参数规模的模型。这些模型利用大量数据进行训练,并且拥有数十亿甚至数千亿个参数。大模型的出现和发展得益于增长的数据量、计算能力的提升以及算法优化等因素。这些模型在各种任务中展现出惊人的性能,比如自然语言处理、计算机视觉、语音识别等。

特点:

利用大量数据进行训练

拥有数十亿甚至数干亿个参数

模型在各种任务中展现出惊人的性能

1.2 InternLM 模型全链条开源

InternLM 是一个开源的轻量级训练框架,旨在支持大模型训练而无需大量的依赖。通过单一的代码库,它支持在拥有数千个 GPU 的大型集群上进行预训练,并在单个 GPU 上进行微调,同时实现了卓越的性能优化。在 1024 个 GPU 上训练时,InternLM 可以实现近 90%的加速效率。

基于 InternLM 训练框架,上海人工智能实验室已经发布了两个开源的预训练模型:InternLM-7B 和 InternLM-20B

Lagent 是一个轻量级、开源的基于大语言模型的智能体(agent)框架,支持用户快速地将一个大语言模型转变为多种类型的智能体,并提供了一些典型工具为大语言模型赋能。通过 Lagent 框架可以更好的发挥 InternLM 的全部性能。

浦语·灵笔是基于书生·浦语大语言模型研发的视觉-语言大模型,提供出色的图文理解和创作能力,结合了视觉和语言的先进技术,能够实现图像到文本、文本到图像的双向转换。使用浦语·灵笔大模型可以轻松的创作一篇图文推文,也能够轻松识别一张图片中的物体,并生成对应的文本描述。

2 InternLM-Chat-7B 智能对话 Demo

使用InternStudio中的 A100(1/4) 机器和InternLM-Chat-7B模型部署一个智能对话 Demo。

2.1 准备工作

创建开发机

进去开发机(左上角可以切换 JupyterLab终端和 VScode

进入终端,在终端输入

bash

 命令,进入 conda` 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

conda create --name internlm-demo --clone=/root/share/conda_envs/internlm-base

可以通过

conda info -e

检查环境

并在环境中安装运行 demo 所需要的依赖

# 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

2.2 模型下载

InternStudio平台的 share 目录下已经为我们准备了全系列的 InternLM 模型,所以我们可以直接复制即可。使用如下命令复制:

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

法2:

import torch
from modelscope import snapshot_download, AutoModel, AutoTokenizer
import os
model_dir = snapshot_download('Shanghai_AI_Laboratory/internlm-chat-7b', cache_dir='/root/model', revision='v1.0.3')

2.3 代码准备

cd /root/code
git clone https://gitee.com/internlm/InternLM.git
cd InternLM
git checkout 3028f07cb79e5b1d7342f4ad8d11efad3fd13d17

将 /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

2.4 终端运行

我们可以在 /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()

messages = []

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

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

2.5 web demo 运行

我们切换到 VScode 中,运行 /root/code/InternLM 目录下的 web_demo.py 文件,输入以下命令后,配置本地端口(5.2),将端口映射到本地。在本地浏览器输入 http://127.0.0.1:6006 即可。(注意:配置好不要关闭终端)

streamlit run web_demo.py --server.address 127.0.0.1 --server.port 6006

项目结束可以通过vgpu-smi命令,检查当前显存占用

3 Lagent 智能体工具调用 Demo

使用 InternStudio 中的 A100(1/4) 机器、InternLM-Chat-7B 模型和 Lagent 框架部署一个智能工具调用 Demo。

3.1 模型下载

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

法2:

import torch
from modelscope import snapshot_download, AutoModel, AutoTokenizer
import os
model_dir = snapshot_download('Shanghai_AI_Laboratory/internlm-chat-7b', cache_dir='/root/model', revision='v1.0.3')

3.2 Lagent 安装

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

不要把.忘记

3.4 Demo 运行

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

4. 浦语·灵笔图文理解创作 Demo

使用InternStudio中的 A100(1/4) * 2 机器和 internlm-xcomposer-7b 模型部署一个图文理解创作 Demo 。

4.1 模型下载

share 目录下已经为我们准备了全系列的 InternLM 模型,所以我们可以直接复制即可。使用如下命令复制:

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

法二:

pip install modelscope==1.9.5

4.2 代码准备

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

4.3 Demo 运行

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

配置好本地接口

5. 通用环境配置

5.1 pip、conda 换源

5.1.1 pip 换源

临时使用镜像源安装,如下所示:some-package 为你需要安装的包名

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

设置pip默认镜像源,升级 pip 到最新的版本 (>=10.0.0) 后进行配置,如下所示:

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

如果您的 pip 默认源的网络连接较差,临时使用镜像源升级 pip:

python -m pip install -i https://mirrors.cernet.edu.cn/pypi/web/simple --upgrade pip
5.1.2 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
  • WindowsC:\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。

快速配置

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
EOF

5.2 配置本地端口

使用本地终端,生成 SSH 密钥对

默认情况下是在 ~/.ssh/ 目录中

可以用cat工具查看

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。

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

本地输入开发机的端口xxx

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