Warning

gradio.Warning("A warning occured ⛔️!", duration=5)

Description

This function allows you to pass custom warning messages to the user. You can do so simply by writing `gr.Warning('message here')` in your function, and when that line is executed the custom message will appear in a modal on the demo. The modal is yellow by default and has the heading: "Warning." Queue must be enabled for this behavior; otherwise, the warning will be printed to the console using the `warnings` library.

Example Usage

import gradio as gr
def hello_world():
    gr.Warning('This is a warning message.')
    return "hello world"
with gr.Blocks() as demo:
    md = gr.Markdown()
    demo.load(hello_world, inputs=None, outputs=[md])
demo.queue().launch()

Initialization

message: str

default = "Warning issued."

The warning message to be displayed to the user. Can be HTML, which will be rendered in the modal.

duration: float | None

default = 10

The duration in seconds that the warning message should be displayed for. If None or 0, the message will be displayed indefinitely until the user closes it.

visible: bool

default = True

Whether the error message should be displayed in the UI.
