您好，我这里复现出来了，应该是最新版的flask_babel接口发生了变化，请您暂时先使用 pip install flask_babel==2.0.0 来解决这一问题

hi，2023.01.16 VDL依赖的flask_babel发布了新的v3.0.0版本，接口做了一个更新，如果您有相同的问题，请暂时先使用pip install flask_babel==2.0.0降级到v2.0.0版本使用。

有最终解决方案了吗？

有最终解决方案了吗？

安装新版本的visualdl就不会出现这个问题，2.5之后的VisualDL版本适配了最新的flask_babel接口

The error

I have the same problem and I don't know what the solution is :(
