ZeroGPU has not been initialized when trying to use space in other space

Spaces
2

Zero GPU spaces will cause an error if the spaces library is not imported first. (This has been made even stricter by a recent specification change.)

In addition, at least one function with the @spaces decorator must be present or an error will occur as well.
Dummy functions are fine.

import spaces
import os
import gradio as gr
from huggingface_hub import HfApi
from gradio_client.exceptions import AuthenticationError

    pass

    # Try to get the token from environment variable
    hf_token = os.environ.get('api')
    
    if not hf_token:
        print("Warning: HUGGINGFACE_TOKEN environment variable not set.")
        print("Attempting to use Hugging Face CLI login...")
    
    try:
        # Attempt to load the space
        iface = gr.load(
            name="My space",
            hf_token=hf_token,
            src="spaces"
        )
