This isn't working for me. I tried running the following code:

import gradio as gr


def a(img):
    return ["lion.jpg", "cantina.wav"]


with gr.Blocks() as demo:
    with gr.Row():
        with gr.Column():
            with gr.Row():
                input_img = gr.File()
            with gr.Row():
                btn = gr.Button(value="submit")
        with gr.Column():
            with gr.Row():
                output_img = gr.File()

    btn.click(fn=a, inputs=[input_img], outputs=[output_img])

demo.launch(inbrowser=True)
