GPU、NVIDIA Graphics Drivers、CUDA、CUDA Toolkit和cuDNN的关系
- GPU:物理显卡。
- NVIDIA Graphics Drivers:物理显卡驱动。
- CUDA:一种由NVIDIA推出的通用并行计算架构,是一种并行计算平台和编程模型,该架构使GPU能够解决复杂的计算问题。在安装NVIDIA Graphics Drivers时,CUDA已经捆绑安装,无需另外安装。
- CUDA Toolkit:包含了CUDA的runtime API、CUDA代码的编译器nvcc(CUDA也有自己的语言,代码需要编译才能执行)和debug工具等。简单言之,可以将CUDA Toolkit视为开发CUDA程序的工具包。需要自己下载安装。此外,在安装CUDA Toolkit时,还可以选择是否捆绑安装NVIDIA Graphics Drivers显卡驱动,因此就可以简略我们的步骤。
- cuDNN:基于CUDA Toolkit,专门针对深度神经网络中的基础操作而设计基于GPU的加速库。需要自己下载安装,其实所谓的安装就是移动几个库文件到指定路径。
使用情形判断
仅仅使用PyTorch
在只使用torch的情况下,不需要安装CUDA Toolkit和cuDNN,只需要显卡驱动,conda或者pip会为我们安排好一切。
安装顺序应该是:NVIDIA Graphics Drivers
->PyTorch
使用torch的第三方子模块
需要安装CUDA Toolkit。
在安装一些基于torch的第三方子模块时,譬如tiny-cuda-nn、nvdiffrast、simple-knn。如果没有安装CUDA Toolkit,torch/utils/cpp_extension.py
会报错如下:
shell
File "....../torch/utils/cpp_extension.py", line 1076, in CUDAExtension
library_dirs += library_paths(cuda=True)
File "....../torch/utils/cpp_extension.py", line 1203, in library_paths
if (not os.path.exists(_join_cuda_home(lib_dir)) and
File "....../torch/utils/cpp_extension.py", line 2416, in _join_cuda_home
raise OSError('CUDA_HOME environment variable is not set. '
OSError: CUDA_HOME environment variable is not set. Please set it to your CUDA install root.
这个报错的意思是找不到CUDA的环境变量路径。这个环境变量是只有安装了CUDA Toolkit之后才会设置的。
这个报错在仅仅使用pytorch时没有影响,因为pytorch在安装时已经准备好了一切,不需要CUDA环境变量。但是,我们现在需要安装其他子模块,就必须要解决这个问题了。
对于做深度学习的研究者,使用其他子模块是经常会碰到的,因此,笔者建议直接安装CUDA Toolkit,在安装CUDA Toolkit的时候捆绑安装显卡驱动。
因此,安装顺序应该是:NVIDIA Graphics Drivers
(可跳过,在安装CUDA Toolkit的时候捆绑安装)->CUDA Toolkit
->PyTorch
->cuDNN
安装NVIDIA Graphics Drivers(可跳过)
前言
在安装CUDA Toolkit
的时候可以选择捆绑安装NVIDIA Graphics Drivers显卡驱动。因此,这一步完全可以跳过,但笔者依旧先写出来。
Linux
法一:图形化界面安装(推荐)
换好源之后更新升级。必须要升级。否则,安装的n卡驱动是无法生效的!而且,下次重启进入Linux之后,连图形化界面都不会出现!!
shell
sudo apt update
sudo apt upgrade
安装必要依赖。必须要安装gcc
、g++
、cmake
。否则,安装的n卡驱动是无法生效的!而且,下次重启进入Linux之后,连图形化界面都不会出现!!
shell
sudo apt install gcc cmake
sudo apt install g++
然后直接下载安装即可:
法二:手动下载文件后命令行安装(不推荐)
笔者没有使用过此方法,也不推荐此方法。在能用图形化界面的情况下就不要多此一举了。
windows
法一:GeForce Experience自动安装
去NVIDIA官网下载GeForce Experience,安装好GeForce Experience之后可以在这个应用里面直接下载最新的驱动。
法二:手动安装
在同样的页面手动搜索对应型号的显卡驱动,下载安装。
检验安装
shell
nvidia-smi
如果有类似下面的输出,那么NVIDIA Graphics Drivers就已经安装了:

安装CUDA Toolkit
查看显卡驱动版本情况
CUDA Toolkit对刚刚安装的显卡驱动有版本要求,具体可以去此处查询。2024.1查询的关系如下:
如果你跳过了安装显卡驱动的步骤,那么你就下载一个最新的CUDA Toolkit好了,它会捆绑安装适配的显卡驱动。
如果你已经安装了显卡驱动,那么可以键入如下指令查询自己的显卡驱动版本:
shell
nvidia-smi
可以在下面看到我的版本是525.147.05

Linux
进入官网选择合适的版本。然后根据自己的设备一步步选择安装即可。
完成选择之后,应该有类似界面。根据官网的步骤一步一步来即可。
根据官网步骤,可以看到给出了三种安装方式。笔者在安装的时候先尝试了第二种,官网步骤如下:
shell
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.0-1_all.deb
sudo dpkg -i cuda-keyring_1.0-1_all.deb
sudo apt-get update
sudo apt-get -y install cuda
然后在第三步报错如下:
shell
han@ASUS-TUF-Gaming-F15-FX507ZR:~$ sudo apt-get -y install cuda
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:
libnvidia-common-525 : Conflicts: libnvidia-common
libnvidia-common-545 : Conflicts: libnvidia-common
nvidia-kernel-common-525 : 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.
根据提示信息,是因为我现在已经有libnvidia-common-525
和nvidia-kernel-common-525
,无法再安装libnvidia-common
和nvidia-kernel-common
,需要更换现有的软件包。理论上,这个问题有两个解决方案:
- 替换软件包
shell
sudo apt-get remove libnvidia-common-525 nvidia-kernel-common-525
sudo apt-get install libnvidia-common nvidia-kernel-common
- 放弃
apt
,使用aptitude
安装
shell
sudo aptitude install cuda
笔者这里都没有尝试,而是改成了官网的另外一种安装方式:
shell
wget https://developer.download.nvidia.com/compute/cuda/11.8.0/local_installers/cuda_11.8.0_520.61.05_linux.run
sudo sh cuda_11.8.0_520.61.05_linux.run
执行这个run程序之后会解压一段时间,要有一些耐心,然后就会有安装引导,一路yes之后来到这里:
- 注意点1:如果跳过了显卡驱动安装的,这里就勾选第一个
Driver
。笔者已经安装了显卡驱动,自然就不用再勾选Driver
了。然后安装即可。 - 注意点2:如果这里勾选
Kernel Objects
,会导致安装不成功。笔者暂时不清楚原因,可能是因为已经安装了显卡驱动的原因。总之,这里不要勾选Kernel Objects
。
笔者在选择Install
之后的安装过程中还出现dkms
未安装报错,于是sudo apt install dkms
,再次尝试安装,就成功了,然后出现:
shell
===========

Driver: Not Selected
Toolkit: Installed in /usr/local/cuda-11.8/
Please make sure that
- PATH includes /usr/local/cuda-11.8/bin
- LD_LIBRARY_PATH includes /usr/local/cuda-11.8/lib64, or, add /usr/local/cuda-11.8/lib64 to /etc/ld.so.conf and run ldconfig as root
To uninstall the CUDA Toolkit, run cuda-uninstaller in /usr/local/cuda-11.8/bin
***WARNING: Incomplete installation! This installation did not install the CUDA Driver. A driver of version at least 520.00 is required for CUDA 11.8 functionality to work.
To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run --silent --driver
Logfile is /var/log/cuda-installer.log
根据提示,我们添加环境变量。请读者根据自己的安装的版本自行修改以下命令的版本号:
shell
echo "export LD_LIBRARY_PATH="/usr/local/cuda-11.8/lib64:\$LD_LIBRARY_PATH"" >> ~/.bashrc
echo "export PATH="/usr/local/cuda-11.8/bin:\$PATH"" >> ~/.bashrc
然后安装就完成了。
Windows
win系统下比较简单,进入官网选择合适的版本,直接下载exe可执行程序,进入引导安装即可。
- 注意点:同样根据自己是否安装过显卡驱动来勾选要不要装显卡驱动。
环境变量会自动设置好,不需要手动设置。安装程序会自动添加以下CUDA_PATH_V11_8
和CUDA_PATH
这2个环境变量:
shell
CUDA_PATH_V11_8=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8
CUDA_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8
安装程序还会自动在Path
环境变量中添加以下2项:
shell
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.8\libnvvp
检验安装
重新打开一个终端查看:
shell
nvcc -V
应该有如下类似的输出:
shell
nvcc: NVIDIA (R) Cuda compiler driver

版本切换
Linux
cuda的软链接位于/usr/local/
,输入如下命令查看:
shell
ls -l /usr/local/
应该有类似如下的输出:
shell
han@ASUS-TUF-Gaming-F15-FX507ZR:~$ ls -l /usr/local/
total 40
lrwxrwxrwx 1 root root 21 1月 27 16:43 cuda -> /usr/local/cuda-11.8/

drwxr-xr-x 8 root root 4096 1月 23 22:09 share
drwxr-xr-x 2 root root 4096 8月 9 2022 src
可以看到现在的cuda是链接到了我刚刚安装的cuda-11.8.一台设备可以安装不同的CUDA Toolkit版本,想要切换版本,只需要改变这个软链接即可。
假如我还有一个CUDA Toolkit12.0,可以用如下指令切换:
shell
ls -snf /usr/local/cuda-12.0/ /usr/local/cuda
Windows
修改之前自动添加的CUDA_PATH
环境变量到对应目录:
shell
CUDA_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.0
修改之前自动添加到Path
环境变量下的那两个项目:
shell
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.0\bin
C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v12.0\libnvvp
Linux卸载CUDA Toolkit
再次回顾安装完成后的summary:
shell
===========

Please make sure that

To install the driver using this installer, run the following command, replacing <CudaInstaller> with the name of this run file:
sudo <CudaInstaller>.run --silent --driver
Logfile is /var/log/cuda-installer.log
可以知道只需要输入类似的指令:(自行更改版本号)
shell
sudo /usr/local/cuda-11.8/bin/cuda-uninstaller
安装PyTorch
查看显卡驱动的CUDA支持版本情况
同样是这个指令:
shell

可以在下面看到我的最大支持的CUDA版本是12.0

下载pytorch
打开pytorch的官网,输入对应自己设备环境的pytorch安装指令即可。着重注意刚刚安装的显卡驱动的可支持CUDA的最高版本,我们选择的pytorch的CUDA版本要低于显卡驱动的可支持CUDA的最高版本。例如,我刚刚查询到我的显卡驱动可支持CUDA最高版本为12.0
,那么我就选择11.8
,如下图这样:
当然也可以选择conda安装。
安装cuDNN
cuDNN对已经安装的CUDA版本有要求。进入官网,选择合适的版本,界面如下:
下载即可。安装的官方文档在这里。
Linux
按官方文档,先安装依赖:
shell
sudo apt-get install zlib1g
法一:下载tar压缩包解压(推荐)
下载好之后解压缩:
shell
tar -xvf cudnn-linux-*-archive.tar.xz
然后复制文件并赋予权限就完成了:
shell
sudo cp cudnn-*-archive/include/cudnn*.h /usr/local/cuda/include
sudo cp -P cudnn-*-archive/lib/libcudnn* /usr/local/cuda/lib64
sudo chmod a+r /usr/local/cuda/include/cudnn*.h /usr/local/cuda/lib64/libcudnn*
法二:下载deb包安装(不推荐)
deb包安装反而要复杂一些。
- 下载好之后dpkg安装一下:
shell
sudo dpkg -i cudnn-local-repo-*.deb
- 导入GPG key并更新:
shell
sudo apt-get install libcudnn8=x.x.x.x-1+cudaX.Y
这里的x
和y
根据自己的版本自己调整
- 再安装几个依赖:
shell
sudo apt-get install libcudnn8=x.x.x.x-1+cudaX.Y
sudo apt-get install libcudnn8-dev=x.x.x.x-1+cudaX.Y
sudo apt-get install libcudnn8-samples=x.x.x.x-1+cudaX.Y
这里的x
和y
也自己的版本略微调整
Windows
Windows只有解压缩安装的方式。下载并解压缩好zip文件,然后复制库文件如下:
- 复制
bin\cudnn*.dll
到C:\Program Files\NVIDIA\CUDNN\v8.x\bin
。 - 复制
include\cudnn*.h
到C:\Program Files\NVIDIA\CUDNN\v8.x\include
。 - 复制
lib\cudnn*.lib
到C:\Program Files\NVIDIA\CUDNN\v8.x\lib
。
然后修改PATH
环境变量,在其中添加一个项目:
shell
C:\Program Files\NVIDIA\CUDNN\v8.x\bin
检验安装
执行/usr/local/cuda/extras/demo_suite/deviceQuery
,应该有以下类似输出:
