This class allows you to pass custom error messages to the user. You can do so by raising a gr.Error("custom message") anywhere in the code, and when that line is executed the custom message will appear in a modal on the demo.
Example:
import gradio as gr
def divide(numerator, denominator):
if denominator == 0:
raise gr.Error("Cannot divide by zero!")
gr.Interface(divide, ["number", "number"], "number").launch()
Demos: calculator, blocks_chained_events
