Gradio 界面的 4 种类型
到目前为止,我们一直假设构建 Gradio 演示需要同时具备输入和输出。但对于机器学习演示来说,并不总是如此:例如,无条件图像生成模型不需要任何输入,但会生成一张图像作为输出。
事实证明,gradio.Interface
类实际上可以处理 4 种不同类型的演示:
- Standard demos 标准演示:同时具有独立的输入和输出(例如图像分类器或语音转文本模型)
- Output-only demos 仅输出演示:不接受任何输入,但会产生输出(例如无条件图像生成模型)
- Input-only demos 仅输入演示:不产生任何输出,但会接受某种形式的输入(例如保存您上传到外部持久数据库的图像的演示)
- Unified demos 统一演示:同时具有输入和输出组件,但这些组件是相同的。这意味着生成的输出将覆盖输入(例如文本自动完成模型)
根据演示类型的不同,用户界面(UI)会有略微不同的外观:
我们来看一下如何使用 Interface
类构建每种类型的演示,以及示例:
标准演示 (Standard demos)
要创建具有输入和输出组件的演示,只需在 Interface()
中设置 inputs
和 outputs
参数的值。以下是一个简单图像滤镜的示例演示:
$code_sepia_filter $demo_sepia_filter
仅输出演示 (Output-only demos)
那么仅包含输出的演示呢?为了构建这样的演示,只需将 Interface()
中的 inputs
参数值设置为 None
。以下是模拟图像生成模型的示例演示:
$code_fake_gan_no_input $demo_fake_gan_no_input
仅输入演示 (Input-only demos)
同样地,要创建仅包含输入的演示,将 Interface()
中的 outputs
参数值设置为 None
。以下是将任何上传的图像保存到磁盘的示例演示:
$code_save_file_no_output $demo_save_file_no_output
统一演示 (Unified demos)
这种演示将单个组件同时作为输入和输出。只需将 Interface()
中的 inputs
和 outputs
参数值设置为相同的组件即可创建此演示。以下是文本生成模型的示例演示:
$code_unified_demo_text_generation $demo_unified_demo_text_generation
