I found a strange issue!!!

[Lym2333]

I found a strange issue, I was using nnUNetv1
when training ending, it didn't exit the terminal or stop after the training was over? I must use crtl+c to break it!
After that, I tried to run predict program, when it comes to over, the system abruptly exits the user login screen, it happend 2 more times. I'm really confused. (Using 'all' folds)
