大模型,顾名思义就是指使用参数量巨大的模型,参数量为数十亿或百亿,可以使用一个模型完成多种任务,是实现通用人工智能的途径。
InternLM是一个轻量级训练框架,自己也体验了一下,使用起来确实方便,不需要大量的依赖就可以开始训练了。我们在有了大模型之后,并不能将其直接在业务中应用起来,还要将其与环境结合训练出智能体,而Lagent就是实现这个功能的。
本节一共要实现3个demo,这里注重实现,先看到效果,不会太注重原理,原理的知识要后面慢慢补。
项目地址:https://github.com/InternLM/tutorial/blob/main/helloworld/hello_world.md
我们这里使用的模型主要是拥有70亿参数的InternLM-7B,其使用数千个GPU进行训练,并且支持在单个GPU上进行微调。
第一步就是进行环境的配置,这里我们在Intern studio中创建一个开发机
之后我们进入开发机,是下面这个页面,有三种开发模式,很人性化呀
这里我们因为我之前完成了第一个demo,所以已经有了虚拟环境了,所以这里我直接激活了,没有的先按照文档里的弄一下。然后把依赖的包都安装一下。
其实最好的一点就是不同的开发机之间的文件居然是共享的,这真是太方便了,我本来合计做笔记就把上一个开发机删除了,这里我重新弄一个还有上面的文件,那么我直接就可以运用了。
mkdir -p /root/model/Shanghai_AI_Laboratory
cp -r /root/share/temp/model_repos/internlm-chat-7b /root/model/Shanghai_AI_Laboratory
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')
通过运行上面的命令就可以得到7B的模型了。
cd /root/code
git clone https://gitee.com/internlm/InternLM.git
cd InternLM
git checkout 3028f07cb79e5b1d7342f4ad8d11efad3fd13d17
然后之后将里面的web_demo的模型路径改为自己模型的路径
创建一下下面图片上的文件,之后复制下面的代码
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.replace(' ', '') if input_text == "exit": break response, history = model.chat(tokenizer, input_text, history=messages) messages.append((input_text, response)) print(f"robot >>> {response}")
之后在终端上运行这个代码
这里有一点比较麻烦,就是要ssh连接,第一次弄了好久,现在再弄一次(我这里是因为放假回家了,就使用我的笔记本电脑了),
先生成ssh密钥对,一顿回车就行,然后找到这个文件
ssh-keygen -t rsa
之后这个密钥到开发机中:
之后我们得到我们的id号:我的id是33978
先在本地运行上图的代码,
这里会先会报个错,先运行一下红框里面的单词我们先在studio的vs code下运行下面的代码。
这里的话点击这个连接,会出现下面这个页面,要加载很长时间。
然后下面这个页面
这个demo就到这里结束了。
下面开始第二个demo,InternLM-Chat-7B 模型和Lagent框架部署一个智能工具调用 Demo。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。

在运行demo之前一定要先在本地运行 ssh -CNg -L 6006:127.0.0.1:6006 root@ssh.intern-ai.org.cn -p 33978
然后点击这个链接:之后就可以看到下面的页面:
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
cd /root/code/InternLM-XComposer
python examples/web_demo.py \
--folder /root/model/Shanghai_AI_Laboratory/internlm-xcomposer-7b \
--num_gpus 1 \
--port 6006
看见下面这个输出,然后加载模型,
加载模型后点击那个链接,就可以体验效果了。
如下:
我们打开pycharm
先安装包
pip install -U huggingface_hub
但是之后运行会出现bug,后直接在,命令行中运行成功了
开始下载,但是好慢呀。
上面是下载模型的文件的方式,下面我们下载一个20B模型的配置文件。并且这里选择使用ModelScope进行下载当个文件,先对其进行安装:
pip install modelscope==1.9.5
pip install transformers==4.35.2
接下来使用我的代码
from modelscope.hub.file_download import model_file_download
model_dir = model_file_download('Shanghai_AI_Laboratory/internlm-chat-20b',file_path='config.json' ,revision='master')
下载成功
