如何從 ubuntu 中完全刪除 cuda？

Question

我有 ubuntu 18.04，不小心安裝了 cuda 9.1 來運行 Tensorflow-gpu，但似乎 tensorflow-gpu 需要 cuda 10.0，所以我想先通過執行來刪除 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).

然后我嘗試運行“apt --fix-broken install”，但出現以下錯誤：

Reading package lists... Done

Correcting dependencies... Done
The following additional packages will be installed:
  libcublas-dev

如何徹底刪除cuda？

Answer 1

有兩個東西——nvidia 驅動程序和 cuda 工具包——你可能想要刪除它們。 如果您已使用apt-get安裝，請使用以下命令從系統中完全刪除軟件包：

刪除 cuda 工具包：

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

要刪除 Nvidia 驅動程序：

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

如果您已通過源文件安裝（假設默認位置為 /use/local），則使用以下命令將其刪除：

sudo rm -rf /usr/local/cuda*

從 cuda 11.4 開始，提供了卸載程序腳本。 將其用於卸載：

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

如果您遇到包損壞的問題，那么自從您將 repo 添加到 apt/sources.lst 后就發生了。 運行以下命令將其刪除：

sudo vim /etc/apt/sources.list

轉到包含對 Nvidia repo 的引用的行，並通過在行前附加 # 對其進行注釋，例如：

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

然后運行

sudo apt-get update 

這將解決問題。

Answer 2

我解決了這個問題如下：

sudo apt-get purge nvidia*
sudo apt-get autoremove
sudo apt-get autoclean
sudo rm -rf /usr/local/cuda*

這將完成工作。

Answer 3

轉到 - /usr/local/cuda-10.2/bin

運行 sudo ./cuda-uninstaller

檢查所有選項，然后它將被自動卸載

Answer 4

要刪除 CUDA 工具包：

$ sudo apt-get --purge remove "*cublas*" "*cufft*" "*curand*" \
 "*cusolver*" "*cusparse*" "*npp*" "*nvjpeg*" "cuda*" "nsight*" 

要刪除 NVIDIA 驅動程序：

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

要清理卸載：

$ sudo apt-get autoremove

Answer 5

刪除 CUDA 工具包：

sudo apt-get --purge remove "*cublas*" "*cufft*" "*curand*" "*cusolver*" "*cusparse*" "*npp*" "*nvjpeg*" "cuda*" "nsight*"
