autodl在 python下检查torch出现上述情况，但是我上午用的时候还好好的，吃了个饭回来再运行就这样了，我看别的博主说uninstall再install，试了不是版本问题

而且我在windows的cmd下import torch是正常的，长这样

然后我换了个autodl文件夹，很神奇，又正常了，我的work1.1在tmp文件夹下，并且tmp下没有其他文件

>>> import torch
>>> torch.__version__
'1.12.1'

这肯定是work1.1里某个文件出错了，观察错误解释，一通操作发现我有一个文件命名是select.py，这个python里应该有个包也叫select，导致程序分辨不出来应该用哪个，改成select_sam.py，完结撒花
