Jetson依赖说明

更新时间：2021-10-21

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jetsonUtilities或者jtop来查看jetpack版本。

1.使用jetsonUtilities

下载jetsonUtilities到本地，然后执行如下python脚本：

nano@jetson-nano:~$ python jetsonInfo.py
NVIDIA Jetson AGX Xavier [16GB]
 L4T 32.5.0 [ JetPack 4.5 ]
   Ubuntu 18.04.5 LTS
   Kernel Version: 4.9.201-tegra
 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
 Vision Works: 1.6.0.501
 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。

2.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
Client:
 Debug Mode: false
 
Server:
 Containers: 38
  Running: 21
  Paused: 0
  Stopped: 17
 Images: 12
 Server Version: 19.03.6
 Storage Driver: overlay2
  Backing Filesystem: extfs
  Supports d_type: true
  Native Overlay Diff: true
 Logging Driver: json-file
 Cgroup Driver: cgroupfs
 Plugins:
  Volume: local
  Network: bridge host ipvlan macvlan null overlay
  Log: awslogs fluentd gcplogs gelf journald json-file local logentries splunk syslog
 Swarm: inactive
 Runtimes: nvidia runc
 Default Runtime: nvidia
 Init Binary: docker-init
 containerd version:
 runc version:

   Profile: default
 Kernel Version: 4.9.140-tegra
 Operating System: Ubuntu 18.04.5 LTS
 OSType: linux
 Architecture: aarch64
 CPUs: 4
 Total Memory: 3.871GiB
 Name: jetson-nano
 ID: O7GP:DDD5:5CIR:LEWJ:2BQ3:4WIW:VA4H:JDCP:5VGL:L2K3:PLZ7:KBHO
 Docker Root Dir: /var/lib/docker
 Debug Mode: false
 Registry: https://index.docker.io/v1/
 Labels:
 Experimental: false
 Insecure Registries:
  127.0.0.0/8
 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 restart docker

四、库文件依赖

EasyEdge场景依赖库文件：easyedge_runtime_j44.csv，需下载该文件并将其放置在 Jetson 设备 /etc/nvidia-container-runtime/host-files-for-container.d/ 目录下，如下图所示：

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
# R32 (release), REVISION: 4.3, GCID: 21589087, BOARD: t210ref, EABI: aarch64, DATE: Fri Jun 26 04:38:25 UTC 2020

2.查看cuda-driver版本

查看cudu驱动版本，可以使用一下命令：

nano@jetson-nano:~$  dpkg -l | grep cuda-driver
ii  cuda-driver-dev-10-2                          10.2.89-1                                        arm64        CUDA Driver native dev stub library

3.查看TensorRT版本

查看TensorRT版本，可以使用一下命令：

nano@jetson-nano:~$  dpkg -l | grep TensorRT
ii  graphsurgeon-tf                               7.1.3-1+cuda10.2                                 arm64        GraphSurgeon for TensorRT package
