Bug: Can't access space by gradio_client since gradio 4.x

I’ve tested on

  • Gradio 3.x on local machine (success)
  • Gradio 4.x on local machine (success)
  • Gradio 3.x on HuggingFace public space (success)
  • Gradio 3.x on HuggingFace private space with proper token space (success)
  • Gradio 4.x on HuggingFace public space (success)
  • Gradio 4.x on HuggingFace private space with proper token ( :broken_heart: bug!)

with gradio_client (python)

Server side app.py:

import gradio as gr

def greet(name):
    return "Hello " + name + "!!"

iface = gr.Interface(fn=greet, inputs="text", outputs="text")
iface.launch( show_error=True, server_name='' , share=True)

Client side code:


from gradio_client import Client
import time

def call():
    client=Client('myusername/test', \
                  hf_token='hf_xxxxxxxxxxxxxxxxxxxxxxxxx' \
    client.view_api()  # success

    r = client.predict('john', fn_index=0,  api_name="/predict") # fail
    return r

r = call()

I got result:

Loaded as API: https://myusername-test.hf.space ✔

The view_api() successfully got API usage,
which means I got the access to my private space.
But predict() can’t work.

Hi @dabgy sorry this is a bug that we’ll fix soon. Please follow Gradio APIs breaks calling private endpoints on HF · Issue #6430 · gradio-app/gradio · GitHub for updates.
