nvidia-smi：未找到命令，但 GPU 运行正常

我试图在我的服务器上安装一些软件包，这需要对一些 CUDA 库进行一些更新。但现在我最终得到了

nvidia-smi: command not found，

甚至我的 GPU 也像以前一样正常工作。那么可能出现什么问题，我该如何解决？一些信息：

问题是，我可以nvidia-smi: command not found在不安装任何其他 ppa 的情况下解决这个问题（在我尝试安装某个软件包之前没有发生过）吗apt purge nvidia-*？这是一个共享服务器，所以我不想弄乱任何东西

答案1

nvidia-smi通过安装nvidia-utils，如下所示：

$ sudo apt-get install nvidia-smi     
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package nvidia-smi is a virtual package provided by:
  nvidia-utils-440 440.44-0ubuntu0~0.18.04.1
  nvidia-utils-435 435.21-0ubuntu0.18.04.2
  nvidia-utils-430 430.64-0ubuntu0~gpu18.04.1
  nvidia-utils-415 415.27-0ubuntu0~gpu18.04.2
  nvidia-utils-410 410.104-0ubuntu0~18.04.1
  nvidia-utils-390 390.129-0ubuntu0~gpu18.04.1
You should explicitly select one to install.

E: Package 'nvidia-smi' has no installation candidate

因此，在您的情况下，您需要安装 nvidia-utils-440。
