Install CUDA 11.1 and Pytorch 1.7 on CentOS 7

How to Install CUDA 11.1 + Pytorch 1.7


=================================================
Install CUDA 11.1
=================================================

下载：https://developer.download.nvidia.com/compute/cuda/11.1.0/local_installers/cuda-repo-rhel7-11-1-local-11.1.0_455.23.05-1.x86_64.rpm
文档：https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html



===== Step One:
 
 Pre-installation Actions [https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#pre-installation-actions] 
 
!!! Important: 
You may need to update kernel if ` yum install kernel-devel-$(uname -r) kernel-headers-$(uname -r)` fails.
How to update kernel: `yum install kernel kernel-tools kernel-tools-libs` [https://www.golinuxcloud.com/how-to-update-kernel-rhel-centos-7-yum-linux/] 



===== Step Two: 
 Package Manager Installation [https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#package-manager-installation]

===== Step Three:
 Post-installation Actions [https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html#post-installation-actions]

===== Step Four: Install proper drivers for Graphic cards
[ https://www.server-world.info/en/note?os=CentOS_7&p=nvidia]

===== Step Five: Compile samples
# cuda-install-samples-11.1.sh  [dir]
# make -k -j

检查命令
nvidia-smi
lspci | grep -i nvi
./bin/x86_64/linux/release/deviceQuery
