参考了:
Ubuntu18.04查看显卡信息并安装NVDIA显卡驱动driver + Cuda + Cudnn
通过 conda 虚拟环境进行安装的话, 参考 ubuntu安装cuda,cudnn,pytorch , 但是要注意安装时的版本选择.
感觉通过 conda 虚拟环境进行安装, 是个更好的选择， 但是自己安装后 Pytorch 不能调用虚拟环境中的 cuda, 所以又更改了虚拟环境的环境变量, 来调用系统的 cuda, 参见 Conda 虚拟环境中配置环境变量 (具体来说是 Pytorch 虚拟环境调用系统 CUDA)
利用命令 lshw -c video 进行查看:
dell@dell-Tower:~$ lshw -c video

其中显卡具体型号为 [Quadro P2000] (关于该显卡当然可以百度更多的信息: NVIDIA Quadro P2000显卡).
利用 ubuntu-drivers devices (输入这个命令后可能需要等几秒才会出结果) 查看可以用的驱动:
dell@dell-Tower:~$ ubuntu-drivers devices

driver : oem-somerville-meta - third-party free
driver : oem-release - third-party free
选择这个 driver : nvidia-driver-510 - distro non-free recommended, 然后去 NVDIA driver search page 搜索显卡需要的驱动型号并下载 (注意: 如果后面要安装 CUDA 则并不需要单独安装驱动, 因为 cuda 安装包里是有驱动的).
nouveau 驱动是 Ubuntu 默认的开源显卡驱动，与 Nvidia 显卡驱动一起使用会导致兼容性问题，比如卡在登录界面无法进入图形界面.
如何禁用参考了 解决NVIDIA-SMI has failed because it couldn‘t communicate with the NVIDIA driver.
使用 lsmod | grep nouveau 命令查看 nouveau 是否禁用, 若没有任何输出则说明已经禁用, 如果由如下的输出, 则表示没有禁用
dell@dell-Tower:~$ lsmod | grep nouveau
nouveau 2064384 28
mxm_wmi 16384 1 nouveau
drm_ttm_helper 16384 1 nouveau
ttm 69632 2 drm_ttm_helper,nouveau
drm_kms_helper 258048 1 nouveau

drm 557056 15 drm_kms_helper,drm_ttm_helper,ttm,nouveau
wmi 32768 7 intel_wmi_thunderbolt,dell_wmi,wmi_bmof,dell_smbios,dell_wmi_descriptor,mxm_wmi,nouveau
(1) 利用下面的命令
sudo bash -c "echo blacklist nouveau > /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
sudo bash -c "echo options nouveau modeset=0 >> /etc/modprobe.d/blacklist-nvidia-nouveau.conf"
(2) 查看是否正确写入文件
dell@dell-Tower:~$ cat /etc/modprobe.d/blacklist-nvidia-nouveau.conf
blacklist nouveau
options nouveau modeset=0
(3) 更新并重启
sudo update-initramfs -u
sudo reboot
(4) 重启后, 检查是否禁用
dell@dell-Tower:~$ lsmod | grep nouveau
dell@dell-Tower:~$
因为 CUDA 中带有 N 卡的驱动, 所以直接选择正确的 CUDA 版本进行安装.
(1) CUDA 下载地址: https://developer.nvidia.com/cuda-toolkit
(2) 英伟达官方的cuda和驱动的对应: NVIDIA CUDA Toolkit Release Notes
由 NVIDIA CUDA Toolkit Release Notes 中的图表所示
结合本机器可安装的驱动版本 driver : nvidia-driver-510 - distro non-free recommended, 所以可以直接选择 CUDA 11.6.x 的版本进行安装.
从 https://developer.nvidia.com/cuda-toolkit 中进行下载并选择自己的系统, 然后官网会给出安装步骤, 如下图
直接采用上面的安装步骤, wget https://developer.download.nvidia.com/compute/cuda/11.6.2/local_installers/cuda-repo-ubuntu2004-11-6-local_11.6.2-510.47.03-1_amd64.deb 命令就是下载 .deb 安装包, 一般就直接下载到当前目录下, 因为我这里是 /home, 所以就直接在 /home/ 目录下了.
dell@dell-Tower:~$ sudo apt-get -y install cuda

runfile[local] 的安装方式Ubuntu20.04下CUDA、cuDNN的详细安装与配置过程（图文） 中提到:
CUDA的run文件虽然比另外两种安装方法的文件大，但是它包含了所有的依赖库文件，所以采用相对来说很容易安装成功。
安装官网给出的方式:
$ wget https://developer.download.nvidia.com/compute/cuda/11.6.2/local_installers/cuda_11.6.2_510.47.03_linux.run
$ sudo sh cuda_11.6.2_510.47.03_linux.run
其中 wget https://developer.download.nvidia.com/compute/cuda/11.6.2/local_installers/cuda_11.6.2_510.47.03_linux.run 命令将 cuda_11.6.2_510.47.03_linux.run 下载到了 /home/ 目录下.
运行 sudo sh cuda_11.6.2_510.47.03_linux.run 时, 会在 Terminal 中显示一个框, 选择 accept (忘记截图了), 接着又会有个框, 直接选择 Install, 如下图
这次安装成功了, 并有如下提示
dell@dell-Tower:~$ sudo sh cuda_11.6.2_510.47.03_linux.run
===========

Driver: Installed
Toolkit: Installed in /usr/local/cuda-11.6/
Please make sure that
- PATH includes /usr/local/cuda-11.6/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-11.6/lib64, or, add /usr/local/cuda-11.6/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.6/bin
To uninstall the NVIDIA Driver, run nvidia-uninstall
Logfile is /var/log/cuda-installer.log
sudo gedit ~/.bashrc
在 ~/.bashrc 的最后添加下面的内容 (注意自己安装的版本号)
# user-add: cuda
export PATH=/usr/local/cuda-11.6/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/cuda-11.6/lib64:$LD_LIBRARY_PATH
export CUDA_HOME=/usr/local/cuda
其中 /usr/local/cuda 其实是一个软链接 (链接到了 /usr/local/cuda-11.6), 可以通过 ll 命令查看
dell@dell-Tower:~$ ll /usr/local/cuda
lrwxrwxrwx 1 root root 21 4月 25 16:37 /usr/local/cuda -> /usr/local/cuda-11.6//
配置完环境变量之后, 需要更新一下 (或者通过重启)
source ~/.bashrc
然后通过 nvcc --version 查看是否安装成功
dell@dell-Tower:~$ nvcc --version

有如上提示的表示安装成功.
同时查看一下所设置的路径
dell@dell-Tower:~$ echo "$CUDA_HOME"
/usr/local/cuda
在 /usr/local/cuda-11.6/samples 中有个 README_CUDA_Samples.txt 文件:
CUDA samples have moved! Please find up-to-date CUDA samples on our GitHub repository:
https://github.com/nvidia/cuda-samples
利用 git clone (我这里 git clone 速度远比网页上直接下载快得多)
git clone https://github.com/NVIDIA/cuda-samples.git
$ cd <sample_dir>
$ make
make 中提示如下错误
...

按照提示, 直接百度 x86_64-conda_cos6-linux-gnu-c++, 经过搜索可能是没安装 gxx_linux-64, 首先 sudo -i
dell@dell-Tower:~$ sudo -i
(base) root@dell-Tower:~# conda install gxx_linux-64
(以防万一) 同时再安装
apt install g++-aarch64-linux-gnu
最后再
make clean
make
最终 make 成功, 尝试一个例子, 如下

Ubuntu18.04查看显卡信息并安装NVDIA显卡驱动driver + Cuda + Cudnn
中列出了几个可能的问题, 可以作为参考.
CUDNN 是一个SDK，是一个专门用于神经网络的加速包，注意，它跟我们的CUDA没有一一对应的关系，即每一个版本的CUDA可能有好几个版本的cuDNN与之对应，但一般有一个最新版本的cuDNN版本与CUDA对应更好。
cuda与cudnn需要满足关系:
https://developer.nvidia.com/rdp/cudnn-archive
我搜了下 cudnn 的安装, 发现网上的方法很多都是下载一个压缩包, 解压后将文件夹复制到 cuda 目录下, 但是官网又提供了 deb 的安装包, 就没弄懂有什么区别, 参考这篇博客, 大概写了下两者的区别: 安装cudnn时, library和deb模式的区别
① download the tgz format:
为Linux选择CUDNN库
此安装相对简单，只需下载，解压缩，将相应的文件复制到指定的目录，并授予权限。
② download deb format:
Runtime and Developer version区别：Developer library 包含在Ubuntu系统上开发深度学习所需的cudnn头文件。 如果您不需要开发和编译任何深度学习程序，只需使用它们来运行某些深度。 要了解应用程序，只需下载Runtime library 就足够了。
但是, 这个描述已经不再适用当前的情况了, 目前 cudnn 已经没有 Runtime 和 Developer 的 deb 包了, 只有一个, 如下图
那么就只能同时安装这两个包了, 具体可以参考 Ubuntu20.04下CUDA、cuDNN的详细安装与配置过程（图文）
下面是自己的安装过程:
(1). 下载并解压 Local Installer for Linux x86_64(Tar), 得到下面的目录
(2). 将解压得到的目录中 cudnn/include 和 cudnn/lib 目录下的内容复制到 /usr/local/cuda-11.6/include 和 /usr/local/cuda-11.6/lib64 中, 但是需要注意, cudnn/lib 中有很多软链接:
dell@dell-Tower:~/Downloads/cudnn-linux-x86_64-8.3.3.40_cuda11.5-archive/lib$ ll
total 2777120
drwxrwxr-x 2 dell dell 4096 4月 26 15:45 ./

lrwxrwxrwx 1 dell dell 27 4月 26 15:45 libcudnn_adv_train_static_v8.a -> libcudnn_adv_train_static.a
...
...
所以在复制 cudnn/lib 中的内容时需要用 cp -d 命令:
dell@dell-Tower:~$ cd Downloads/cudnn-linux-x86_64-8.3.3.40_cuda11.5-archive/lib/
dell@dell-Tower:~/Downloads/cudnn-linux-x86_64-8.3.3.40_cuda11.5-archive/lib$ sudo cp -d ./* /usr/local/cuda-11.6/lib64/
[sudo] password for dell:
dell@dell-Tower:~/Downloads/cudnn-linux-x86_64-8.3.3.40_cuda11.5-archive/lib$ cd ../include/
dell@dell-Tower:~/Downloads/cudnn-linux-x86_64-8.3.3.40_cuda11.5-archive/include$ sudo cp ./* /usr/local/cuda-11.6/include/
然后赋予权限:
dell@dell-Tower:~$ sudo chmod a+r /usr/local/cuda-11.6/include/cudnn.h /usr/local/cuda-11.6/lib64/libcudnn*
[sudo] password for dell:
查看 CUDNN 的信息：
dell@dell-Tower:~$ cat /usr/local/cuda-11.6/include/cudnn_version.h | grep CUDNN_MAJOR -A 2
#define CUDNN_MAJOR 8
#define CUDNN_MINOR 3
#define CUDNN_PATCHLEVEL 3
--
#define CUDNN_VERSION (CUDNN_MAJOR * 1000 + CUDNN_MINOR * 100 + CUDNN_PATCHLEVEL)
#endif /* CUDNN_VERSION_H */
(3). 下载 Local Installer for Ubuntu20.04 x86_64(Deb) 包, 直接双击后利用 Ubuntu 自带的 Ubuntu Software 进行安装的.
这一部分可以参考 macOS conda 安装指定版本的 Pytorch (虽然给出的是在 macOS 下安装, 但这里同样适用) 进行 Pytorch 的安装.
