Solution for Gradio v3.2.1b0 (latest)

[TheLastBen]

In the new Gradio, gr.update() works better if the component type is included, for example gr.Textbox.update(), also you need to include the label and the value in gr.update (preferably anything supported by gr.update to be included).

Fix :

Replace the two first functions change_image_editor_mode and update_image_mask in ui_functions.py :

def change_image_editor_mode(choice, cropped_image, resize_mode, width, height):
    if choice == "Mask":
        return [gr.Image.update(visible=False), 
                gr.Image.update(visible=True),
                gr.Button.update("Generate", variant="primary", visible=False),
                gr.Button.update("Generate", variant="primary", visible=True),
                gr.Button.update("Advanced Editor", visible=False),
                gr.Radio.update(choices=["Keep masked area", "Regenerate only masked area"],
                label="Mask Mode",
                value="Regenerate only masked area", visible=True),
                gr.Slider.update(minimum=1, maximum=10, step=1, label="How much blurry should the mask be? (to avoid hard edges)", value=3, visible=True)]
    else:
        return [gr.Image.update(visible=True), 
                gr.Image.update(visible=False),
                gr.Button.update("Generate", variant="primary", visible=True),
                gr.Button.update("Generate", variant="primary", visible=False),
                gr.Button.update("Advanced Editor", visible=True),
                gr.Radio.update(choices=["Keep masked area", "Regenerate only masked area"],
                label="Mask Mode",
                value="Regenerate only masked area", visible=False),
                gr.Slider.update(minimum=1, maximum=10, step=1, label="How much blurry should the mask be? (to avoid hard edges)", value=3, visible=False)]


def update_image_mask(cropped_image, resize_mode, width, height):
    resized_cropped_image = resize_image(resize_mode, cropped_image, width, height) if cropped_image else None
    return gr.Image.update(value=resized_cropped_image)`

Replace txt2img_submit_on_enter.change in webui.py by :

txt2img_submit_on_enter.change(lambda x: gr.Textbox.update(label="Prompt", placeholder="A corgi wearing a top hat as an oil painting.", value=txt2img_defaults['prompt'], show_label=False, max_lines=1 if x == 'Yes' else 25), txt2img_submit_on_enter, txt2img_prompt)
