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
