我有一台装有 Ubuntu 18.04.1 和 anaconda 4.5.8 的新电脑，我正在尝试安装 tensorflow_gpu。显卡已安装在主板上，但驱动程序尚未安装。
我尝试按照本教程在 Ubuntu 18.04.1 中安装 tensorflow_gpu。

第一步是输入：
$ nvidia-smi
由此我得到：
Command 'nvidia-smi' not found, but can be installed with:
sudo apt install nvidia-340
sudo apt install nvidia-utils-390
因此我输入它们，认为这将允许 nvidia-smi 工作。
未找到命令“nvidia-smi”，但可以使用以下命令安装：
$sudo apt install nvidia-340
这样就安装OK了
但是当我运行 sudo apt install nvidia-utils-390 时：
desktop:~$ sudo apt install nvidia-utils-390

现在，当我尝试 nvidia-smi 时，我得到：
desktop:~$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
Q1.) 我该如何撤消/修复这个损坏的安装？
Q2.) 我应该安装什么，以便当我输入 nvidia-smi 时，它会给我如教程中所示的输出，这样我就可以按照本教程的其余部分进行操作！
