我正在尝试为Titan Xp安装NVIDIA驱动程序。我输入以下内容进行安装：
sudo apt-get install nvidia-418
安装运行没有错误。但是，重新启动后，不会加载驱动程序。这是nvidia-smi命令给出的错误：
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.
这是完整的安装日志（在终端中）：

A modprobe blacklist file has been created at /etc/modprobe.d to prevent Nouveau from loading. This can be reverted by deleting /etc/modprobe.d/nvidia-graphics-drivers.conf.
A new initrd image has also been created. To revert, please replace /boot/initrd-4.15.0-70-generic with /boot/initrd-$(uname -r)-backup.
