Ubuntu清除GPU显存

在Ubuntu运行代码的时候，有时会出现代码退出了，显存依然在占用的情况。

//显存查看指令
nvidia-smi

手动清除掉显存，方法有二：

• 重启

• 命令行

先执行该代码查看所有占用显存的进程

fuser -v /dev/nvidia* 

可发现进程如下

                     USER        PID ACCESS COMMAND
/dev/nvidia0:        hnj        1660 F...m compizhnj        4388 F...m chromehnj        4418 F...m chromehnj        8542 F...m pythonhnj       23641 F...m TeamViewer
/dev/nvidiactl:      hnj        1660 F...m compizhnj        4388 F...m chromehnj        4418 F...m chromehnj        8542 F...m pythonhnj       23641 F...m TeamViewer
/dev/nvidia-modeset: hnj        1660 F.... compizhnj        4388 F.... chromehnj        4418 F.... chromehnj       23641 F.... TeamViewer
/dev/nvidia-uvm:     hnj        8542 F.... python

找到Python对应的进程号，一一杀之：

kill -9 8542

有时候要杀两三条python
最后得到干净的显存，继续运行代码吧！
