whisper-api
介绍
使用openai的开源项目winsper语音识别开源模型封装成openai chatgpt兼容接口
软件架构
使用uvicorn、fastapi、openai-whisper等开源库实现高性能接口

使用说明
- 下载代码
- 安装 ffmpeg https://ffmpeg.org/download.html
- 安装依赖 项目根目录下执行命令
pip install -r requirements.txt - 运行代码 项目根目录下执行命令
python main.py
这里的 http://0.0.0.0:3003 就是连接地址。

docker
- docker打包命令
docker build -t whisper .
2.docker命令启动
gpu显卡模式
docker run -itd --name whisper-api -p 3003:3003 --gpus all --restart=always whisper
- 默认 ACCESS_TOKEN=sk-tarzan
cpu模式
docker run -itd --name whisper-api -p 3003:3003 --restart=always whisper
- 默认 ACCESS_TOKEN=sk-tarzan
鉴权模式
docker run -itd --name whisper-api -p 3003:3003-e ACCESS_TOKEN=yourtoken --gpus all --restart=always whisper
docker run -itd --name whisper-api -p 3003:3003-e ACCESS_TOKEN=yourtoken --restart=always whisper
- yourtoken 修改你设置的鉴权token,接口调用header 里传
Authorization:Bearer sk-tarzan
docker日志查看
docker logs -f [容器id或容器名称]
配置文件
options.json
{"model_size": "base","language": "Chinese"
}
- 可结合one-api,接入FastGPT等rag开源项目使用，使用教程如下：
