Install CUDA#

公式ページが最強#

CUDA のアーカイブでインストールしたいバージョンを選択
https://developer.nvidia.com/cuda-toolkit-archive

Platform の選択 ../../_images/install_cuda_0.png

指示通り，コマンドを実行する．
dev をダウンロードするので，temp フォルダなどを作るとファイル整理しやすい
../../_images/install_cuda_1.png

(推奨)バージョン指定する（指定しない場合は最新のCUDAになる）

- $ sudo apt-get -y install cuda
+ $ sudo apt install cuda-12-1

再起動

$ reboot

PATHを通す

$ echo "export PATH=/usr/local/cuda/bin:$PATH" >> ~/.bashrc
$ echo "export LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATH" >> ~/.bashrc

Terminalの再起動か設定ファイルのリロード

$ source ~/.bashrc

インストールの確認

$ nvcc -V

Troubleshooting#

１．apt install cuda で以下のエラー

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 nvidia-kernel-common-535 : Conflicts: nvidia-kernel-common
 nvidia-kernel-common-545 : Conflicts: nvidia-kernel-common
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

apt install nvidia-kernel-common-535 をしても以下のエラー

解決方法
エラーメッセージ通り，dev パッケージを上書きする

$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/nvidia-kernel-common-535_535.129.03-0ubuntu1_amd64.deb
$ sudo apt -f install
$ sudo apt update
