AttributeError: 'NoneType' object has no attribute 'data'

不知道为什么当我在使用wenetspeech下使用lhotse时做data prepare ，报了如下错误，思考了很久，并不知道该如何做才能解决？

这是我的ltose的版本：lhotse-1.27.0.dev0+git.66b95ba.clean

Possibly one of the manifest paths is corrupted or doesn’t exist?

请问这个该如何排查呢？我使用的是prepare.sh这个脚本，并没有做任何修改

pdb 单步调试 @Airgods

pdb 单步调试 @Airgods

请问这个以prepare.sh文件启动，随后报错的是环境中配置lthose包，这个如何做到gdb单步调试呢

[csukuangfj]

请学习一下什么是pdb

重复一下，是pdb，不是gdb

你自己去看脚本，看跑的是哪个Python代码，传的什么参数
