情况说明：

Vscode执行代码后，程序所占用显存未得到释放，导致无法运行其他程序。

（占用7号GPU的进程是我的另外一个进程，与本文讨论的问题无关。）

解决办法：

1. 定位占用GPU显存的PID

fuser -v /dev/nvidia*

2. 查看指定进程的信息

ps -f -p 285448

可以发现该进程的PPID（其父进程的PID）是1，说明该进程不是我占用7号GPU的进程生成的，并且现在只有它在使用0号GPU。可以推断出这个进程是因为程序运行错误导致其没有被关闭，因此可以手动关闭该进程。

3. 杀死指定进程，释放显存

kill -9 2885448

再查看GPU情况，可以看到0号GPU的显存已经被释放，现在的GPU显存占用情况是正常的。
