torch.cuda.is_available()返回false

—用实验室的服务器跑代码，突然有一天显示GPU不可用了，排查了一堆，师兄帮着修改了.bashrc文件，在他的电脑一切正常，但自己的vscode一直返回False

CMD终端返回为True，怀疑是vscode环境变量被污染了

CMD终端查看环境变量的结果：（xxx代指用户名）

与CMD终端的环境变量相比频繁出现.vscode-server/cli/servers/…

一开始参考了这篇博客的处理方式https://juejin.cn/post/7356049143954997302

找到.vscode-server/extensions/ms-python.python-2024.12.3-linux-x64/python_files/deactivate/bash/envVars.txt里面的PATH并修改，但是重连服务器发现PATH又自动修改回来了

---

解决方案：

直接在CMD终端连接服务器输入以下命令删除.vscode-server文件夹

rm -rf ~/.vscode-server/

---

重新打开vscode连接服务器（会生成新的.vscode-server文件夹）
可喜可贺~
