wired device not managed
Most probably your interface appears in /etc/network/interfaces. By default, NetworkManager does not manage interfaces that appear in /etc/network/interfaces. You can change this behaviour.
To do this - in a terminal:
sudo nano /etc/NetworkManager/NetworkManager.conf
change the line managed=false to managed=true
Save, stop and start network manager:
sudo service network-manager restart

VNC with Default desktop [Recommended]
Refer to:
## install vncserver
yum install tigervnc-server xorg-x11-fonts-Type1
## copy vnc systemc config file, :3 is an example, other number can be used
cp /lib/systemd/system/[email protected] /etc/systemd/system/vncserver@:3.service
## replace with a user name
grep USER /lib/systemd/system/[email protected]
# 2. Replace with the actual user name and edit vncserver
ExecStart=/usr/bin/vncserver_wrapper %i
## change into
# su -
## run below command to set user's vnc password
$ vncserver

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
当中可能遇到的错误情况处理：
1. centos7 yum 错误 This system is not registered with an entitlement server [https://blog.csdn.net/whatday/article/details/106106767]
