class espnet3.publication.demo.assets.UIAsset

Bases: object

Base class for one demo UI asset type.

Demo configs refer to UI assets by ui.inputs[].type and ui.outputs[].type. Each asset implementation is responsible for building the corresponding Gradio component.

ESPnet3 developers can add new built-in assets by subclassing UIAsset and registering the subclass in DEFAULT_UI_ASSETS in this module.

Initialize one UI asset and cache the imported gradio module.
