警告

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

描述

此函数允许你向用户传递自定义警告消息。你可以通过在函数中简单地编写 `gr.Warning('message here')` 来实现，当该行代码执行时，自定义消息将出现在演示的模态框中。模态框默认为黄色，标题为：“Warning”。必须启用队列才能实现此行为；否则，警告将使用 `warnings` 库打印到控制台。

使用示例

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()

初始化

🔗

message: str

默认值 = "Warning issued."

要向用户显示的警告消息。可以是 HTML，将在模态框中呈现。

🔗

duration: float | None

默认值 = 10

警告消息应显示的持续时间，以秒为单位。如果为 None 或 0，消息将无限期显示，直到用户关闭它。

🔗

visible: bool

默认值 = True

是否应在 UI 中显示警告消息。

🔗

title: str

默认值 = "Warning"

要在模态框顶部向用户显示的标题。
