Jetson nano配置

镜像烧录

镜像官网地址，有烧录流程

查看Ubuntu系统

点击右上角红色圈出来的地方
选择**“About This Computer”**
jetson nano的Ubuntu系统是18.04

查看处理器类型，aarch64

yu@yu-desktop:~$ uname -aLinux yu-desktop 4.9.201-tegra #1 SMP PREEMPT Fri Feb 19 08:40:32 PST 2021 aarch64 aarch64 aarch64 GNU/Linux

换国内源，加快下载速度

yu@yu-desktop:~$ cd /etc/aptyu@yu-desktop:/etc/apt$ sudo cp sources.list sources.list.bakyu@yu-desktop:/etc/apt$ sudo gedit sources.list

第二句代码是备份本来的源，
第三句使用gedit工具打开源，删除原来的源，加入中科大或者清华源

中科大

查看ip地址并固定ip地址，没成功

yu@yu-desktop:~$ ifconfig省略一些信息，主要是下面这部分wlan0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500 inet 192.168.1.103  netmask 255.255.255.0  broadcast 192.168.1.255 inet6 fe80::1b9f:791f:1ff5:50ed  prefixlen 64  scopeid 0x20<link> ether 34:13:e8:5e:70:31  txqueuelen 1000  (Ethernet) RX packets 63711  bytes 70627505 (70.6 MB) RX errors 0  dropped 0  overruns 0  frame 0 TX packets 29785  bytes 7601765 (7.6 MB) TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

修改环境变量

yu@yu-desktop：~$ sudo gedit  ~/.bashrc

在最后添加这三行

export CUDA_HOME=/usr/local/cudaexport LD_LIBRARY_PATH=/usr/local/cuda/lib64:$LD_LIBRARY_PATHexport PATH=/usr/local/cuda/bin:$PATH

重新执行bashrc，查看cuda和cudnn型号 10.2，V10.2.89

yu@yu-desktop：~$ source ~/.bashrcyu@yu-desktop：~$ nvcc -Vnvcc: NVIDIA (R) Cuda compiler driverCopyright (c) 2005-2019 NVIDIA CorporationBuilt on Wed_Oct_23_21:14:42_PDT_2019Cuda compilation tools, release 10.2, V10.2.89

查看opencv版本：4.1.1

yu@yu-desktop：~$ pkg-config opencv4 --modversion

jetpack版本：4.4（opencv4.1.1版本对应的jetpack版本就是4.4）
tensorrt版本：7.1
