Jupyter Notebook JSONDecodeError 打开文件

如何解决Jupyter Notebook JSONDecodeError 打开文件

预期行为： 打开一个没有错误的 mp3

实际行为： 我使用了下面的脚本，

来自pydub 导入音频段

song = AudioSegment.from_mp3("audio.mp3")

并且有一个 JSONDecodeError

JSONDecodeError：期望值：第 1 行第 1 列（字符 0）

JSONDecodeError                           Traceback (most recent call last)
