Qwen-Audio-chat WebDemo 部署

Qwen-Audio 介绍

Qwen-Audio 是阿里云研发的大规模音频语言模型（Large Audio Language Model）。Qwen-Audio 可以以多种音频 (包括说话人语音、自然音、音乐、歌声）和文本作为输入，并以文本作为输出。

环境准备

在autodl平台中租一个3090等24G显存的显卡机器，如下图所示镜像选择PyTorch-->2.0.0-->3.8(ubuntu20.04)-->11.8（11.3版本以上的都可以） 接下来打开刚刚租用服务器的JupyterLab图像， 并且打开其中的终端开始环境配置、模型下载和运行演示。 Alt text pip换源和安装依赖包

# 升级pip
python -m pip install --upgrade pip
# 更换 pypi 源加速库的安装
pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple

pip install modelscope==1.9.5

pip install accelerate
pip install tiktoken
pip install einops
pip install transformers_stream_generator==0.0.4
pip install scipy
pip install torchvision
pip install pillow
pip install tensorboard
pip install matplotlib
pip install transformers==4.32.0
pip install gradio==3.39.0
pip install nest_asyncio

模型下载

使用 modelscope 中的snapshot_download函数下载模型，第一个参数为模型名称，参数cache_dir为模型的下载路径。

在 /root/autodl-tmp 路径下新建 download.py 文件并在其中输入以下内容，粘贴代码后记得保存文件，如下图所示。并运行 python /root/autodl-tmp/download.py 执行下载，模型大小为 20 GB，下载模型大概需要10~20分钟

import torch
from modelscope import snapshot_download, AutoModel, AutoTokenizer
from modelscope import GenerationConfig
model_dir = snapshot_download('qwen/Qwen-Audio-Chat', cache_dir='/root/autodl-tmp', revision='master')

代码准备

在/root/autodl-tmp路径下新建 chatBot.py 文件并在其中输入以下内容，粘贴代码后记得保存文件。下面的代码有很详细的注释，大家如有不理解的地方，欢迎提出issue。

运行 demo

在终端中运行以下命令，启动streamlit服务，并按照 autodl 的指示将端口映射到本地，然后在浏览器中打开链接 http://localhost:6006/ ，即可看到聊天界面。

streamlit run /root/autodl-tmp/chatBot.py --server.address 127.0.0.1 --server.port 6006

如下所示：
