cuda云服务器,Ubuntu18.04 云服务器安装NVIDIA-DRIVER，CUDA，CUDnn

nvidia-driver

This section includes instructions for installing the NVIDIA driver on Ubuntu 16.04 LTS and Ubuntu 18.04 LTS distributions using the package manager. The NVIDIA driver requires that the kernel headers and development packages for the running version of the kernel be installed at the time of the driver installation, as well whenever the driver is rebuilt. For example, if your system is running kernel version 4.4.0, the 4.4.0 kernel headers and development packages must also be installed. The kernel headers and development packages for the currently running kernel can be installed with:

$ sudo apt-get install linux-headers-$(uname -r)

Ensure packages on the CUDA network repository have priority over the Canonical repository.

$ distribution=$(. /etc/os-release;echo $ID$VERSION_ID | sed -e 's/\.//g')

$ wget https://developer.download.nvidia.com/compute/cuda/repos/$distribution/x86_64/cuda-$distribution.pin

$ sudo mv cuda-$distribution.pin /etc/apt/preferences.d/cuda-repository-pin-600

Install the CUDA repository public GPG key. Note that on Ubuntu 16.04, replace https with http in the command below.

$ sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/$distribution/x86_64/7fa2af80.pub

Setup the CUDA network repository.

$ echo "deb http://developer.download.nvidia.com/compute/cuda/repos/$distribution/x86_64 /" | sudo tee /etc/apt/sources.list.d/cuda.list

Update the APT repository cache and install the driver using the cuda-drivers meta-package. Use the --no-install-recommends option for a lean driver install without any dependencies on X packages. This is particularly useful for headless installations on cloud instances.

$ sudo apt-get update

$ sudo apt-get -y install cuda-drivers

CUDA

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin

sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600

wget http://developer.download.nvidia.com/compute/cuda/10.2/Prod/local_installers/cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb

sudo dpkg -i cuda-repo-ubuntu1804-10-2-local-10.2.89-440.33.01_1.0-1_amd64.deb

sudo apt-key add /var/cuda-repo-10-2-local-10.2.89-440.33.01/7fa2af80.pub

sudo apt-get update

sudo apt-get -y install cuda

CUDnn

文件下载及解压 进入官网下载压缩包文件: cuDNN Library for Linux

终端解压

sudo tar -xzvf cudnn-10.2-linux-x64-v7.6.5.32.tgz

下载好后的tgz文件和解压后的目录：

cd cuda

文件复制 终端输入以下命令将文件复制到CUDA中

sudo cp cuda/include/cudnn.h /usr/local/cuda/include

sudo cp cuda/lib64/libcudnn* /usr/local/cuda/lib64

sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda/lib64/libcudnn*

复制后即完成cuDNN安装.

验证安装 终端输入：cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2 ，如下显示即安装成功。

cat /usr/local/cuda/include/cudnn.h | grep CUDNN_MAJOR -A 2
