一:概述
这篇文章主要介绍的如何利用8G显存玩转书生大模型Demo,首先先来介绍一下这个模型的特点,书生·浦语Cli*Web Demo这个主要是1.8B但性能不俗性的InternLm2端侧模型,浦语·灵笔LMDeployGradio Demo主要是自由形式的文本,图像组合的视觉语言大模型InternLM-XComposer2,书生·万象LMDeployGradio Demo主要是首个综合性能媲美美国国际闭源商业模型的开源多态模型大模型InternVL2。
二:具体说明
<1>开发机的创建
<2>基础conda环境的配置
首先来为Demo创建一个可用的环境,步骤代码如下所示:
# 创建环境
conda create -n demo python=3.10 -y
# 激活环境
conda activate demo
# 安装 torch
conda install pytorch==2.1.2 torchvision==0.16.2 torchaudio==2.1.2 pytorch-cuda=12.1 -c pytorch -c nvidia -y
# 安装其他依赖
pip install transformers==4.38
pip install sentencepiece==0.1.99
pip install einops==0.8.0
pip install protobuf==5.27.2
pip install accelerate==0.33.0
pip install streamlit==1.37.0
<3>Cli Demo部署InternLM2-Chat-1.8B模型
3.1 创建Demo文件夹以及文件
3.2 在文件中输入下面的代码
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM
model_name_or_path = "/root/share/new_models/Shanghai_AI_Laboratory/internlm2-chat-1_8b"
tokenizer = AutoTokenizer.from_pretrained(model_name_or_path, trust_remote_code=True, device_map='cuda:0')
model = AutoModelForCausalLM.from_pretrained(model_name_or_path, trust_remote_code=True, torch_dtype=torch.bfloat16, device_map='cuda:0')
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("\nUser >>> ")
input_text = input_text.replace(' ', '')
if input_text == "exit":
break
length = 0
for response, _ in model.stream_chat(tokenizer, input_text, messages):
if response is not None:
print(response[length:], flush=True, end="")
length = len(response)
3.3 在命令行中运行python文件
python /root/demo/cli_demo.py
效果图如下图所示:
<4>利用它回答几个问题
4.1 生成300字小故事复现过程
4.2 现在国际市场上主流的编程语言有哪些?简单介绍一下
效果图如下所示:
<5> Streamlit Web Demo部署InternLM2-Chat-1.8B模型
5.1 克隆代码
cd /root/demo
git clone https://github.com/InternLM/Tutorial.git
5.2 利用Streamlit部署Web应用并实现端口映射
cd /root/demo
git clone https://github.com/InternLM/Tutorial.git
cd /root/demo
streamlit run /root/demo/Tutorial/tools/streamlit_demo.py --server.address 127.0.0.1 --server.port 你的SSH端口号
Web页面的效果图如下所示:
