04.Cuda 和Cudnn的安装

1. 参考官方文档安装cuda：

https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=24.04&target_type=deb_local

# wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2404/x86_64/cuda-ubuntu2404.pin

# sudo mv cuda-ubuntu2404.pin /etc/apt/preferences.d/cuda-repository-pin-600

# wget https://developer.download.nvidia.com/compute/cuda/12.6.3/local_installers/cuda-repo-ubuntu2404-12-6-local_12.6.3-560.35.05-1_amd64.deb

# sudo dpkg -i cuda-repo-ubuntu2404-12-6-local_12.6.3-560.35.05-1_amd64.deb

# sudo cp /var/cuda-repo-ubuntu2404-12-6-local/cuda-*-keyring.gpg /usr/share/keyrings/

# sudo apt-get update

# sudo apt-get -y install cuda-toolkit-12-6

1. 配置cuda到环境变量中，似的命令行对nvcc等命令生效

# vi /etc/profile.d/apps-bin-path.sh

cuda_path="/usr/local/cuda-12.6/bin" if [ -n "${PATH##*${cuda_path}}" ] && [ -n "${PATH##*${cuda_path}:*}" ]; then     export PATH="$PATH:${cuda_path}" fi

# source /etc/profile

1. 检查生效与否：

# env |grep PATH

# nvcc --version

1. 安装cudnn

https://developer.nvidia.com/cudnn-downloads?target_os=Linux&target_arch=x86_64&Distribution=Ubuntu&target_version=24.04&target_type=deb_local

wget https://developer.download.nvidia.com/compute/cudnn/9.6.0/local_installers/cudnn-local-repo-ubuntu2404-9.6.0_1.0-1_amd64.deb

wget https://developer.download.nvidia.com/compute/cudnn/9.6.0/local_installers/cudnn-local-repo-ubuntu2404-9.6.0_1.0-1_amd64.deb

sudo dpkg -i cudnn-local-repo-ubuntu2404-9.6.0_1.0-1_amd64.deb

sudo cp /var/cudnn-local-repo-ubuntu2404-9.6.0/cudnn-*-keyring.gpg /usr/share/keyrings/

sudo apt-get update

sudo apt-get -y install cudnn
