前言
最近因为项目需要，每次更新代码都要重新烧录系统，每次初始化都要打开好几个网页来复制命令实在太烦人了，所以将代码整合起来记录一下。

1、JetsonNano风扇自启动
cd /etc
sudo touch rc.local
sudo vim rc.local
#!/bin/bash
sleep 10
sudo /usr/bin/jetson_clocks
sudo sh -c 'echo 255 > /sys/devices/pwm-fan/target_pwm
sudo chmod 755 /etc/rc.local
sudo reboot
2、JetsonNano换源
# 为防止误操作后无法恢复，先备份原文件sources.list
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
# 新建新的源文件source.list
sudo vim /etc/apt/sources.list
# 删掉原来的，粘贴下面的

sudo apt-get update
sudo apt-get upgrade
3、JetsonNano 安装 VNC
sudo apt install vino
sudo ln -s ../vino-server.service /usr/lib/systemd/user/graphical-session.target.wants
gsettings set org.gnome.Vino prompt-enabled false
gsettings set org.gnome.Vino require-encryption false
sudo vim /usr/share/glib-2.0/schemas/org.gnome.Vino.gschema.xml
# 文件最后添加
<key name='enabled' type='b'>
<summary>Enable remote access to the desktop</summary>
<description>
If true, allows remote access to the desktop via the RFB
protocol. Users on remote machines may then connect to the
desktop using a VNC viewer.
</description>
<default>false</default>
</key>
sudo glib-compile-schemas /usr/share/glib-2.0/schemas
gsettings set org.gnome.Vino authentication-methods "['vnc']"
gsettings set org.gnome.Vino vnc-password $(echo -n '你自己的密码'|base64)
sudo reboot
gsettings set org.gnome.Vino enabled true
mkdir -p ~/.config/autostart
vim ~/.config/autostart/vino-server.desktop
[Desktop Entry]
Type=Application
Name=Vino VNC server
Exec=/usr/lib/vino/vino-server
NoDisplay=true
4、JetsonNano 安装测试DeepStream
sudo apt install \
libssl1.0.0 \
libgstreamer1.0-0 \
gstreamer1.0-tools \
gstreamer1.0-plugins-good \
gstreamer1.0-plugins-bad \
gstreamer1.0-plugins-ugly \
gstreamer1.0-libav \
libgstrtspserver-1.0-0 \
libjansson4=2.11-1
去官网下载deepstream，百度直接搜就行，下载好后文件名为：deepstream_sdk_v5.1.0_jetson.tbz2
下载5.1版本的DeepStream需要登陆一下
sudo tar -xvf deepstream_sdk_v5.1.0_jetson.tbz2 -C /
cd /opt/nvidia/deepstream/deepstream-5.1
sudo ./install.sh
sudo ldconfig
测试
cd /opt/nvidia/deepstream/deepstream-5.1/sources/objectDetector_Yolo
CUDA_VER=10.2 make -C nvdsinfer_custom_impl_Yolo
./prebuild.sh
deepstream-app -c deepstream_app_config_yoloV3_tiny.txt
5、JetsonNano 安装Pytorch
提前下好 torch-1.8.0-cp36-cp36m-linux_aarch64.whl
sudo apt-get install python3-pip libopenblas-base libopenmpi-dev
pip3 install Cython
pip3 install numpy torch-1.8.0-cp36-cp36m-linux_aarch64.whl
6、JetsonNano 安装 torchvision
编译的时间可能有点长，耐心等待即可
sudo apt-get install libjpeg-dev zlib1g-dev libpython3-dev libavcodec-dev libavformat-dev libswscale-dev
git clone --branch v0.9.0 https://github.com/pytorch/vision torchvision
cd torchvision
export BUILD_VERSION=0.9.0
python3 setup.py install --user
pip3 install pillow
7、JetsonNano pip换源
mkdir ~/.pip
vim ~/.pip/pip.conf
[global]
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
[install]
trusted-host = https://pypi.tuna.tsinghua.edu.cn
