Hi iam trying to access a hugging face space into other space

my app.py

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

def load_space():
    # 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"
        )
        print("Space loaded successfully!")
        return iface
    except AuthenticationError as e:
        print(f"Authentication error: {e}")
        print("Please make sure you're logged in or using a valid token.")
        return None
    except Exception as e:
        print(f"An error occurred: {e}")
        return None

def main():
    iface = load_space()
    if iface:
        iface.queue(max_size=300)
        iface.launch(debug=False)
    else:
        print("Failed to load the space. Please check the error messages above.")

if __name__ == " __main__":
    main()

```

My output

# runtime error

## ZeroGPU has not been initialized

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.

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

@spaces.GPU
def dummy(): # just a dummy
    pass

def load_space():
    # 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"
        )
        print("Space loaded successfully!")
        return iface
    except AuthenticationError as e:
        print(f"Authentication error: {e}")
        print("Please make sure you're logged in or using a valid token.")
        return None
    except Exception as e:
        print(f"An error occurred: {e}")
        return None

def main():
    iface = load_space()
    if iface:
        iface.queue(max_size=300)
        iface.launch(debug=False)
    else:
        print("Failed to load the space. Please check the error messages above.")

if __name__ == " __main__":
    main()

```
