尝试在 Ubuntu 18.04 上安装 CUDA 9.2

Question

我正在尝试在 Ubuntu 18.04 上安装 CUDA 9.2，遵循 this 网站：

我已经下载了 NVIDIA CUDA Toolkit（shell 脚本 cuda_9.2.88_396.26_linux），但是当我运行它时（$sudo sh cuda_9.2.88_396.26_linux），我得到了：

Installing the NVIDIA display driver...
A system reboot is required to continue installation. Please reboot then run the installer again. 
An attmept has been made to disable Nouveau. 
If this message persists after reboot, please see the display driver log file at /var/log/nvidia-installer.log for more information.

所以，我重新启动并再次运行 shell 脚本 ($sudo sh cuda_9.2.88_396.26_linux)，我得到了相同的消息。这就是 nvidia-installer.log 所说的：

 ERROR: The Nouveau kernel driver is currently in use by your system.  This driver is incompatible with the NVIDIA driver, and must be disabled before proceeding.  Please consult the NVIDIA driver README and your Linux distribution's documentation for details on how to correctly disable the Nouveau kernel driver.
WARNING: One or more modprobe configuration files to disable Nouveau are already present at: /etc/modprobe.d/nvidia-installer-disable-nouveau.conf.  Please be sure you have rebooted your system since these files were written.  If you have rebooted, then Nouveau may be enabled for other reasons, such as being included in the system initial ramdisk or in your X configuration file.  Please consult the NVIDIA driver README and your Linux distribution's documentation for details on how to correctly disable the Nouveau kernel driver.
-> For some distributions, Nouveau can be disabled by adding a file in the modprobe configuration directory.  Would you like nvidia-installer to attempt to create this modprobe file for you? (Answer: Yes)
-> One or more modprobe configuration files to disable Nouveau have been written.  For some distributions, this may be sufficient to disable Nouveau; other distributions may require modification of the initial ramdisk.  Please reboot your system and attempt NVIDIA driver installation again.  Note if you later wish to reenable Nouveau, you will need to delete these files: /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
ERROR: Installation has failed.  Please see the file '/var/log/nvidia-installer.log' for details.  You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.

我已经安装了我的 nvidia 驱动程序。

Answer 1

首先，我会遵循the official guide 包括预安装说明。通读每一行，如果你从一开始就彻底，你会节省时间。

“懒人工作两次”

第二：如果您遵循 Runfile 安装，以下是在 Ubuntu 中禁用 Nouveau 的说明。

1. 检查是否加载了 Nouveau 驱动程序。如果以下命令打印任何内容，则会加载 Nouveau 驱动程序

   $ lsmod | grep nouveau  
   

2. 在 /etc/modprobe.d/blacklist-nouveau.conf 创建一个文件，内容如下：

   blacklist nouveau
   options nouveau modeset=0
   

3. 重新生成内核initramfs：

   $ sudo update-initramfs -u
   

确保在完成后一直执行安装后操作。

最后：确保您正在使用的 Ubuntu 版本被您尝试安装的 CUDA 版本列为支持！！！！当我第一次安装时，我假设是最新的一切的版本都是最好的，但最新版本的 CUDA 不一定能在最新版本的 Ubuntu 上运行。一些更高级的用户可以让它工作，但我不能在那里指导你。检查 CUDA 工具包和 cuDNN 支持的版本（如果您正在使用它）。

祝你好运。安装 cuda 可能有点痛苦，有必要不要跳过任何安装步骤。 youtube 上还有一些有用的视频，如果您遇到困难，可能会有用。
