AttributeError in Gradio Web Server: 'list' object has no attribute 'text_models'

Description:

I followed the instructions to run the WebGUI service in single-model mode by launching the controller, model workers, and Gradio web server. However, when I opened the website, the Gradio web server triggered an error, and the website failed to render correctly.

Error Message and Screenshot:

Potential Issue:

In the load_demo function, we're passing a list as the first argument to load_demo_single(models, url_params). However, it appears that this argument should be a Context object, not a list. The error occurs because the list object doesn't have the text_models attribute, which causes the AttributeError.

Steps to Reproduce:

1. Follow the instructions to install the package and run the WebGUI service in single-model mode.
2. Launch the controller, model workers, and Gradio web server.
3. Open the website and observe the error.

Has this been solved? My temporary solution is to update the load_demo in fastchat/serve/gradio_web_server.py:

def load_demo(url_params, request: gr.Request):
    global models

    ip = get_ip(request)
    logger.info(f"load_demo. ip: {ip}. params: {url_params}")

    if args.model_list_mode == "reload":
        models, all_models = get_model_list(
            controller_url, args.register_api_endpoint_file, vision_arena=False
        )
    
    # Create a Context object with the models
    context = Context()
    context.text_models = models
    context.models = all_models if 'all_models' in locals() else models

    return load_demo_single(context, url_params)
