书生·浦语大模型 实战营第二节 笔记

1.大模型及 InternLM 模型介绍

2 .InternLM-Chat-7B 智能对话 Demo

3 .Lagent 智能体工具调用 Demo

4 .浦语-灵笔图文创作理解 Demo

5.InternLM-Chat-7B 智能对话 Demo

5.1通用环境配置

这里使用书生·浦语的算力平台创建虚拟机

创建好后,我选择使用的是vscode进行连接

然后在终端运行脚本进行配置,从本地克隆一个已有的 pytorch 2.0.1 的环境

bash /root/share/install_conda_env_internlm_base.sh internlm-demo
1

可以使用conda info -e查看已有的python环境

配置完毕后,使用以下命令激活环境

conda activate internlm-demo
1

并在环境中安装运行 demo 所需要的依赖(可能需要换源)

# 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

5.2.模型下载

自己机子搭建的话需要下载相对应模型,这里给出了huggingface下载工具的使用方法

pip install -U huggingface_hub
huggingface-cli download --resume-download intern1m/intern1m-chat-7b --local-dir your_path

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
1
2

5.3.代码准备

首先 clone 代码，在 /root 路径下新建 code 目录，然后切换路径, clone 代码.

mkdir code 
cd /root/code
git clone https://gitee.com/internlm/InternLM.git
1

切换 commit 版本，与教程 commit 版本保持一致，可以让大家更好的复现。

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。

5.4.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()

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}")

然后在终端运行以下命令，即可体验 InternLM-Chat-7B 模型的对话能力。对话效果如下所示：

python /root/code/InternLM/cli_demo.py

5.5.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，查看本教程5.2配置本地端口后，将端口映射到本地。在本地浏览器输入 http://127.0.0.1:6006 即可。

6.InternLM-Chat-7B 智能对话 Demo

我们已经在上一小节配置好了环境,于是配置环境和模型的环境跳过

6.1.Lagent 安装

首先切换路径到 /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

6.2.修改代码

由于代码修改的地方比较多，大家直接将 /root/code/lagent/examples/react_web_demo.py 内容替换为以下代码

Demo 运行

streamlit run /root/code/lagent/examples/react_web_demo.py --server.address 127.0.0.1 --server.port 6006
1

用同样的方法我们依然切换到 VScode 页面，运行成功后，查看本教程5.2配置本地端口后，将端口映射到本地。在本地浏览器输入 http://127.0.0.1:6006 即可。

我们在 Web 页面选择 InternLM 模型，等待模型加载完毕后，输入数学问题 已知 2x+3=10，求x ,此时 InternLM-Chat-7B 模型理解题意生成解此题的 Python 代码，Lagent 调度送入 Python 代码解释器求出该问题的解。

7.浦语·灵笔图文理解创作 Demo

7.1.环境搭建

因为这个Demo环境要求与前两个不太一样,我们可以再创建一个internlm-demo2的conda环境

bash /root/share/install_conda_env_internlm_base.sh internlm-demo2
conda activate internlm-demo2
pip install transformers==4.33.1 timm==0.4.12 sentencepiece==0.1.99 gradio==3.44.4 markdown2==2.4.10 xlsxwriter==3.1.2 einops accelerate
1

7.2.模型下载

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-xcomposer-7b /root/model/Shanghai_AI_Laboratory
1
2

-r 选项表示递归地复制目录及其内容

7.1 代码准备

在 /root/code git clone InternLM-XComposer 仓库的代码

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
1

7.2 Demo 运行

在终端运行以下代码：

cd /root/code/InternLM-XComposer
python examples/web_demo.py  \
    --folder /root/model/Shanghai_AI_Laboratory/internlm-xcomposer-7b \
    --num_gpus 1 \
    --port 6006
1
2
3
4
5

这里 num_gpus 1 是因为InternStudio平台对于 A100(1/4)*2 识别仍为一张显卡。但如果有小伙伴课后使用两张 3090 来运行此 demo，仍需将 num_gpus 设置为 2 。

查看本教程5.2配置本地端口后，将端口映射到本地。在本地浏览器输入 http://127.0.0.1:6006 即可。体验图文创作的功能，如下图所示：
