Gradio client: Calling sync() from within a running loop

Joystickplays commented 9 months ago

Describe the bug

I currently have a Flask app that uses Gradio API for inferencing. If I run it with normal Flask built-in WSGI server, it'll work. However, I want to run it with gunicorn and gevent in my server.

Reproduction

from gevent import monkey
monkey.patch_all()
from gradio_client import Client
from flask import Flask, send_file
import time

app = Flask(__name__)

imageclient = Client("https://diffusers-unofficial-sdxl-turbo-i2i-t2i.hf.space/")
@app.route("/gen")
def gen():
      result = imageclient.predict(
                  None,
                  "A sunny view of the park",   
                  0.9,  
                  2,
                  round(time.time()),   
                  api_name="/predict"
              )
      return send_file(result)

if __name__ == "__main__":
      app.run(host="0.0.0.0", port=5000)

Then run it with gunicorn -k gevent -w 1 <app_name>:app --bind 0.0.0.0:5000 Access 127.0.0.1:5000/gen
