ubuntu - 如何从 ubuntu 中完全删除 cuda？

Question

我有 ubuntu 18.04，不小心安装了 cuda 9.1 来运行 Tensorflow-gpu，但似乎 tensorflow-gpu 需要 cuda 10.0，所以我想先通过执行删除 cuda:

martin@nlp-server:~$ sudo apt-get remove --auto-remove nvidia-cuda-toolkit
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 cuda-libraries-dev-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but 10.1.0.105-1 is to be installed
 cuda-samples-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but 10.1.0.105-1 is to be installed
 cuda-visual-tools-10-1 : Depends: libcublas-dev (>= 10.2.0.168) but 10.1.0.105-1 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

然后我尝试运行“apt --fix-broken install”，但出现以下错误:

The following additional packages will be installed:
  libcublas-dev

如何完全删除cuda？

Answer 1

您可能想要删除两件事——nvidia 驱动程序和 cuda 工具包。
如果您使用 安装易于获取 使用以下命令从系统中完全删除软件包:
要删除 cuda 工具包:

sudo apt-get --purge remove "*cublas*" "cuda*" "nsight*" 

要删除 Nvidia 驱动程序:

sudo apt-get --purge remove "*nvidia*"

如果您通过 安装源文件 (假设默认位置为 /usr/local )然后使用以下命令将其删除:

sudo rm -rf /usr/local/cuda*

从 cuda 11.4 开始，提供了一个卸载程序脚本。将其用于卸载:

# To uninstall cuda
sudo /usr/local/cuda-11.4/bin/cuda-uninstaller 
# To uninstall nvidia
sudo /usr/bin/nvidia-uninstall

如果遇到 的问题破损的包裹 ，自从您将 repo 添加到 apt/sources.lst 后，它就发生了。运行以下命令将其删除:

sudo vim /etc/apt/sources.list

转到包含对 Nvidia repo 的引用的行并通过附加 # 对其进行评论排在前面，例如:

#deb http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /

然后运行

sudo apt-get update 

这将解决问题。
