Jetson依赖说明
更新时间：2022-09-27
一、硬件准备
本文使用的设备是jetson nano，也可以使用Jetson Xavier TX2/NX/AGX等设备。
二、jetpack依赖
本实验使用的模型依赖于JetPack 4.4，在安装 JetPack 时务必安装对应的组件：
- 使用 SDK Manager 安装 JetPack 需要勾选 TensorRT、OpenCV、CUDA、cuDNN 等选项。
- 使用 SD Card Image 方式（仅对 Jetson Nano 和 Jetson Xavier NX 有效）则无需关心组件问题，默认会全部安装。
在已经安装好的Jetson设备上，可以使用apt-cache show nvidia-jetpack、jetsonUtilities和jtop来查看jetpack版本。
1.使用apt-cache show nvidia-jetpack
执行如下命令，查看jetson版本：
nvidia@miivii-tegra:~$ sudo apt-cache show nvidia-jetpack

Description-md5: ad1462289bdbc54909ae109d1d32c0a82.使用jetsonUtilities
下载jetsonUtilities到本地，然后执行如下python脚本：
nano@jetson-nano:~$ python jetsonInfo.py

CUDA 10.2.89
CUDA Architecture: 7.2
OpenCV version: 4.1.1
OpenCV Cuda: NO
CUDNN: 8.0.0.180
TensorRT: 7.1.3.0

VPI: ii libnvvpi1 1.0.15 arm64 NVIDIA Vision Programming Interface library
Vulcan: 1.2.70上述为jetpack 4.5版本的信息。
3.使用jtop
参考jetson_stats官网安装jtop程序，安装命令如下：
# 1. 更新系统包
sudo apt-get update
sudo apt-get upgrade
# 2. 安装pip
sudo apt-get install python-pip
# 3. 检查 pip 是否安装成功
pip -V
# 4.安装jtop
sudo -H pip install -U jetson-stats
# 5.查看系统服务状态
sudo systemctl status jetson_stats
# 6.卸载jtop
sudo pip uninstall jetson-stats
# 7. 查看pip软件清单
pip list安装完毕以后，可以执行jtop命令查看jetson信息，如下图所示：
三、nvidia-docker依赖
jetson设备默认安装了docker，建议使用docker 19.03及以上版本。可以在jetson设备上执行docker info查看docker信息，执行结果如下：
$ docker info

Live Restore Enabled: false如果Default Runtime不是nvidia，而是runc，则修改/etc/docker/daemon.json文件，添加"default-runtime": "nvidia"，修改完毕以后的/etc/docker/daemon.json文件如下所示：
nano@jetson-nano:~$ cat /etc/docker/daemon.json
{
"default-runtime": "nvidia",
"runtimes": {
"nvidia": {
"path": "nvidia-container-runtime",
"runtimeArgs": []
}
}
}修改完毕以后，重启docker，执行如下命令：
sudo systemctl daemon-reload
sudo systemctl restart docker四、库文件依赖
EasyEdge Jetson 推理镜像依赖库文件，需下载对应版本库文件，并将其放置在 Jetson 设备 /etc/nvidia-container-runtime/host-files-for-container.d/ 目录下，如下图所示：
库文件下载地址：
- jetpack 4.4：easyedge_runtime_j44.csv
- jetpack 4.5：easyedge_runtime_j45.csv
五、查看其他信息常用命令
1.查看nv_tegra_release版本
nano@jetson-nano:~$ head -n 1 /etc/nv_tegra_release
