1. 官方例子

• run.py

from fastapi import FastAPI import gradio as gr  CUSTOM_PATH = "/gradio"  app = FastAPI()   @app.get("/") def read_main():     return {"message": "This is your main app"}   io = gr.Interface(lambda x: "Hello, " + x + "!", "textbox", "textbox") app = gr.mount_gradio_app(app, io, path=CUSTOM_PATH)   # Run this from the terminal as you would normally start a FastAPI app: `uvicorn run:app` # and navigate to http://localhost:8000/gradio in your browser. 

运行方式：uvicorn run:app

2. 油管例子

• gradio_ui.py

import gradio as gr   def greet(text: str) -> str:     return text   demo = gr.Interface(     fn=greet,     inputs=gr.components.Textbox(label='Input'),     outputs=gr.components.Textbox(label='Output'),     allow_flagging='never' ) 

• run.py

from fastapi import FastAPI import gradio as gr  from gradio_ui import demo  app = FastAPI()  @app.get('/') async def root():     return 'Gradio app is running at /gradio', 200  app = gr.mount_gradio_app(app, demo, path='/gradio') 

• 运行方式

uvicorn run:app --host 0.0.0.0 --port 5000 

• 注意事项

1. 在命令行中的格式是<文件对象:挂载对象> 2. 文件对象，不要带py 3. 需要在同一个根目录下 

3. 视频演示
