教程参考扫地的小和尚1
为了稳定和不折腾，最好还是装系统推荐的驱动版本吧。
打开设置（software&updates）
选择Additional Drivers
安装推荐的驱动即可。
完成安装后输入
nvidia-smi
进行检测

选择“Archive of Previous CUDA Releases”
找到与显卡驱动“515.65”对应的的cuda版本cuda_11.7.1_515.65.01_linux.run
如图，最下面已经给出了安装命令。网络不好，直接复制wget后面的地址用下载器下载。
最后在文件目录右键鼠标打开命令行进行安装
wget https://developer.download.nvidia.com/compute/cuda/11.7.1/local_installers/cuda_11.7.1_515.65.01_linux.run
sudo sh cuda_11.7.1_515.65.01_linux.run
同意并继续，取消勾选驱动（因为系统已经帮我们装了）
安装完成后会有提示

Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-11.7/Please make sure that
- PATH includes /usr/local/cuda-11.7/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-11.7/lib64, or, add /usr/local/cuda-11.7/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.7/bin
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 515.00 is required for CUDA 11.7 functionality to work.
To install the driver using this installer, run the following command, replacing with the name of this run file:
sudo .run --silent --driverLogfile is /var/log/cuda-installer.log
提示你添加环境变量
sudo gedit ~/.bashrc
或者
vim ~/.bashrc
最后一行添加：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64
export PATH=$PATH:/usr/local/cuda/bin
export CUDA_HOME=$CUDA_HOME:/usr/local/cuda
保存关闭后，应用一下更改
source ~/.bashrc
sudo ldconfig

我采用deb安装的，地址如下。需要注册登录NVIDIA。
https://developer.nvidia.com/rdp/cudnn-download
同样Archived cuDNN Releases （不知道11.x啥意思，我没找到11.7的就装了8.6，最后好像成了）
cudnn-local-repo-ubuntu2004-8.6.0.163_1.0-1_amd64.deb
按照官方文档安装
https://docs.nvidia.com/deeplearning/cudnn/install-guide/index.html#installlinux-deb\
文档说了cuDNN前置条件是
1.装了显卡驱动
2.cuda
3.zlib
2.1.3. Installing Zlib
About this task
For Ubuntu users, to install the zlib package, run:
sudo apt-get install zlib1g
2.3.2. Debian Local Installation
Download the Debian local repository installation package. Before issuing the following commands, you must replace X.Y and 8.x.x.x with your specific CUDA and cuDNN versions.
Procedure
1.Navigate to your directory containing the cuDNN Debian local installer file.
2.Enable the local repository.
sudo dpkg -i cudnn-local-repo-${OS}-8.x.x.x_1.0-1_amd64.deb
Or
sudo dpkg -i cudnn-local-repo-${OS}-8.x.x.x_1.0-1_arm64.deb
3.Import the CUDA GPG key.
sudo cp /var/cudnn-local-repo-*/cudnn-local-*-keyring.gpg /usr/share/keyrings/
4.Refresh the repository metadata.
sudo apt-get update
5.Install the runtime library.
sudo apt-get install libcudnn8=8.x.x.x-1+cudaX.Y
6.Install the developer library.
sudo apt-get install libcudnn8-dev=8.x.x.x-1+cudaX.Y
7.Install the code samples and the cuDNN library documentation.
sudo apt-get install libcudnn8-samples=8.x.x.x-1+cudaX.Y
到download目录打开终端，
sudo dpkg -i cudnn-local-repo-ubuntu2004-8.6.0.163_1.0-1_amd64.deb
提示：
Selecting previously unselected package cudnn-local-repo-ubuntu2004-8.6.0.163.
(Reading database … 206235 files and directories currently installed.)
Preparing to unpack cudnn-local-repo-ubuntu2004-8.6.0.163_1.0-1_amd64.deb …
Unpacking cudnn-local-repo-ubuntu2004-8.6.0.163 (1.0-1) …

To install the key, run this command:
sudo cp /var/cudnn-local-repo-ubuntu2004-8.6.0.163/cudnn-local-B0FE0A41-keyring.gpg /usr/share/keyrings/
按照官方3.提示输入
sudo cp /var/cudnn-local-repo-ubuntu2004-8.6.0.163/cudnn-local-B0FE0A41-keyring.gpg /usr/share/keyrings/
按照官方4.Refresh the repository metadata
sudo apt-get update
打开路径/var/cudnn-local-repo-ubuntu2004-8.6.0.163/
按照5.6.7.的步骤输入
sudo apt-get install libcudnn8=8.6.0.163-1+cuda11.8
sudo apt-get install libcudnn8-dev=8.6.0.163-1+cuda11.8
sudo apt-get install libcudnn8-samples=8.6.0.163-1+cuda11.8
这下就OKK了
2.4. Verifying the Install on Linux
To verify that cuDNN is installed and is running properly, compile the mnistCUDNN sample located in the /usr/src/cudnn_samples_v8 directory in the Debian file.
Procedure
Copy the cuDNN samples to a writable path.
cp -r /usr/src/cudnn_samples_v8/ $HOME
Go to the writable path.
cd $HOME/cudnn_samples_v8/mnistCUDNN
Compile the mnistCUDNN sample.
make clean && make
Run the mnistCUDNN sample.
./mnistCUDNN
If cuDNN is properly installed and running on your Linux system, you will see a message similar to the following:
Test passed!
nvcc warning : The ‘compute_35’, ‘compute_37’, ‘sm_35’, and ‘sm_37’ architectures are deprecated, and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).
https://blog.csdn.net/qq_51182466/article/details/120183001
原因是Makefile中采用了CUDA中的compute capability 3.5、3.7这几种计算能力。而我安装的是CUDA11.7，可能已经将这几种计算能力弃用了。可以用cmake或者GUI进行修改（我不会）

这个教程教了如何写，其中的SMS ? =35 37 50 52 60很像
因此在HOME/cudnn_samples_v8/mnistCUDNN这个目录的makefile中搜索SMS
#Gencode arguments
#Setting SMS inside samples_common.mk
include …/samples_common.mk
打开HOME/cudnn_samples_v8中的samples_common.mk
最后一行
SMS ?= 37 50 53 60 61 62 $(SMS_VOLTA) $(SMS_AMPERE)
删除37
