Jetson TX2 安装jetpack，cuda，opencv

进入ubuntu系统后，默认是16.04的系统，不过都是在命令行下，须要安装图形界面。

在命令行应该有用户名和密码，还有安装教程，基本上是这样

用户：nvidia
密码：nvidia

cd ${HOME}/NVIDIA_INSTALLER
sudo ./installer.sh

以后就能够进入图形界面。

而后须要刷机和安装cuda的，这里推荐使用Jetpack，下载地址

在使用jetpack以前你须要另一台装有ubuntu的电脑，而后在这电脑上安装jetpack，而不是TX2上。

注意将电脑和TX2都连到同一网段，同一路由器就行。

下载以后执行sh文件，而后会跳出 输入密码解压 以后会跳出

这里host-ubuntu的本身的电脑，能够选择什么都不装，Action那栏是no action的状态。 不刷机的话Target-Jetson TX2下Linux for Tegre host Side ... , Flash OS Image to Target也要选择no action。

最后的install on Target能够本身选择安装，建议除了opencv能够以后本身装，其余均可以装上，相似下图：

next会出现确认的选择，所有都选上。

这边填上TX2的IP地址和用户名密码

而后坐等装完。

opencv的安装能够推荐一下网站进行安全，很全： http://dev.t7.ai/jetson/opencv/

所有安装完以后能够测试下。
