一故障表现

一Make prompt界面上传音频后不输入音频内容无法生成.npz文件。

提示信息中表示可以不输入音频内容，但是不输入会报错，这个是个bug，需要输入音频内容才能生成模板.npz文件。

二正确输入信息后无法生成.npz模板文件

长时间无响应，命令行窗口报错：

FileNotFoundError: [WinError 2] 系统找不到指定的文件。

原因是系统中没有找到 ffprobe 工具，这个工具是是 FFmpeg 的一部分，用于提取多媒体文件的信息，包括音频格式、时长等。Gradio 需要使用 ffmpeg 来处理非 WAV 格式的音频文件。

由于制作模板的功能需要使用ffprobe 工具，所以报错

解决办法：

下载ffprobe并加入Path

官网地址：https://ffmpeg.org/download.html

下载地址：https://github.com/BtbN/FFmpeg-Builds/releases/download/latest/ffmpeg-master-latest-win64-gpl-shared.zip

下载完成后解压，进入ffprobe文件夹下的bin目录，复制路径
