TX2入门教程基础篇-查看系统和软件版本参数状态

说明：

• 介绍如何查看TX2系统和软件版本和参数
• 测试TX2版本：Jetpack 3.3, cuda 9.0.252, cudnn7.0, opencv3.3.1, TensorRT4.0.2

步骤：

• 查看Jetson TX2 L4T版本

ubuntu@AiROS:~$ head -n 1 /etc/nv_tegra_release

• 查看TensorRT的版本

ubuntu@AiROS:~$ dpkg -l | grep TensorRT
ii  libnvinfer-dev    4.1.3-1+cuda9.0     arm64        TensorRT development libraries and headers
ii  libnvinfer-samples 4.1.3-1+cuda9.0    arm64        TensorRT samples and documentation
ii  libnvinfer4       4.1.3-1+cuda9.0     arm64        TensorRT runtime libraries
ii  tensorrt          4.0.2.0-1+cuda9.0   arm64        Meta package of TensorRT

• 查看系统版本

ubuntu@AiROS:~$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04 LTS"

• 查看系统l内核：

ubuntu@AiROS:~$ uname -a
