What jetson tx2 is ???
First, the hardware assembly:
1, the Wi-Fi antenna plugged in, the charger can be assembled
2, Interface Description:
USB interface has only one (USB recommended expansion of convenience when the pre-configured connection keyboard and mouse)
can only use the monitor with HDMI
recommendations when using a wired network configuration
Second, the power-up configuration:
And power on the power supply, turning the monitor, keyboard, mouse, and then press the start button on the motherboard of the red, printed circuit board "POWER BTN".
The first boot, the screen will show some tips, step by step, enter the following command:
cd ~/NVIDIA-INSTALL
sudo ./install.sh
reboot
It can open the graphical interface after the restart
the default account password is:
user : nvidia
password : nvidia
Third, the installation JetPack
Jetpack can only be installed by installing NVIDIA SDK Manager
requires a linux host (? Bloggers use ubuntu)
to install a virtual machine ( tutorial )
can also be used to implement a virtual machine (refer to this article )
download JDK manage Download
1, usb line board (type b port) host and the host (USB port) to connect
2, after downloading the installation package SDK manage well, can be installed in the open Linux system.
3, first of all need to login account (not recommended registered on the official website)
official website
2, select the version
3, you can select all agree (lower left corner) 
download will take some time
3、输入jetson tx2 的账号密码，一般上默认的账号密码，如果以及和 liunx 电脑连接ip无需改动
安装完jetpack os的系统后需要重新设置账号密码，再重新输入到里面即可
4、然后点击安装（由于各种原因可能会失败很多次，比如：网络错误等 重新尝试即可）
送上官方教程：点击打开
5、安装完成大家就可以体验这个帅气的系统了
系统：ubuntu 18.04
自带： python 2.7 和 python3.6
CUDA 10.00
tensorfliw–gpu 1.14 、 opencv 等深度学习常见包
四、环境配置
1、ssh配置
//配置ssh
sudo vim /etc/ssh/ssh_config
sudo vim /etc/ssh/sshd_config
//重启
sudo service ssh restrat
2、模式选择：
Jetson TX2是由一个GPU和一个CPU集群组成。CPU集群由双核denver2处理器和四核ARM Cortex-A57组成，通过高性能互连架构连接。拥有６个CPU核心和一个GPU，可以不必自行运行所有性能、功耗来测量最佳的运行状态，因为NVIDIA新的命令行工具Nvpmodel提供５种模式，可以方便地让用户配置CPU状态，以最大限度地提高不同场景下的性能和能耗。
命令行切换模式可以参见

3、固定ip
为了方便稳定等ssh连接，需要固定jetson tx 2 的ip
由于是nvidia 定制系统和一般的ubuntu 18.04不同
Vim教程
//修改
sudo vim /etc/network/interfaces
参照：
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.8.100 //ip
netmask 255.255.255.0
# dns-nameserver 8.8.8.8
dns-nameserver 8.8.8.8 //DNS
保存后
重启服务
sudo /etc/init.d/networking restart
