构建属于你自己的Jetbot

1.     烧录Jetpack 镜像到SD卡  Jetson Download Center

使用的账户和密码均为Jetbot

确认使用自动登录

2.     将SD卡插入Jetson Nano 并开机进入命令行

3.     启用IC2权限

sudo usermod -aG i2c $USER

4.     安装pip和python依赖项

sudo apt-get update

sudo apt install python3-pip python3-pil

sudo pip3 install --upgrade numpy

5.     安装Tensorflow

sudo apt-get update

sudo apt-get install libhdf5-serial-dev hdf5-tools libhdf5-dev zlib1g-dev zip libjpeg8-dev liblapack-dev libblas-dev gfortran

sudo apt-get install python3-pip

sudo pip3 install -U pip testresources setuptools==49.6.0

sudo pip3 install --pre --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v42 tensorflow-gpu

注：验证Tensorflow安装在命令行输入python3进入python环境，然后在python环境内输入import tensorflow，如果没有报错，则tensorflow安装成功

6.     安装PyTorch

注：需要先下载该文件并上传至/home/jetbot/目录   点我进入下载界面

sudo pip3 install torch-1.0.0a0+18eef1d-cp36-cp36m-linux_aarch64.whl

sudo pip3 install torchvision

7.     安装Traitlets

sudo -H python3 -m pip install traitlets==4.3.3

8.     安装Jupter Lab依赖项

sudo apt update

sudo apt -y install curl dirmngr apt-transport-https lsb-release ca-certificates

curl -sL https://deb.nodesource.com/setup_10.x | sudo bash

sudo apt update

sudo apt -y install nodejs npm

9.     安装Jupter Lab

sudo pip3 install jupyter jupyterlab

sudo jupyter labextension install @jupyter-widgets/jupyterlab-manager

sudo jupyter labextension install @jupyterlab/statusbar

jupyter lab --generate-config

# 设置Jupyter Lab密码

jupyter notebook password

# 修改Jupyter Lab配置文件

cd ~/jupyter

sudo nano jupyter_notebook_config.py

# 向配置文件末尾添加如下两行

# c.NotebookApp.allow_origin = '*’

# c.NotebookApp.ip = '0.0.0.0’

10.  安装这个Repo

cd ~

sudo apt install python3-smbus

# 将Jetbot项目从Github克隆下来

git clone https://github.com/NVIDIA-AI-IOT/jetbot

cd jetbot

sudo apt-get install cmake

sudo python3 setup.py install

11.  安装Jetbot服务

cd jetbot/utils

python3 create_stats_service.py

sudo mv jetbot_stats.service /etc/systemd/system/jetbot_stats.service

sudo systemctl enable jetbot_stats

sudo systemctl start jetbot_stats

python3 create_jupyter_service.py

sudo mv jetbot_jupyter.service /etc/systemd/system/jetbot_jupyter.service

sudo systemctl enable jetbot_jupyter

sudo systemctl start jetbot_jupyter

12.  创建文件交换（SWAP）

sudo fallocate -l 4G /var/swapfile

sudo chmod 600 /var/swapfile

sudo mkswap /var/swapfile

sudo swapon /var/swapfile

sudo bash -c 'echo "/var/swapfile swap swap defaults 0 0" >> /etc/fstab'

13.  将Jetbot notebook复制到/home/jetbot/下

cp -r ~/jetbot/notebooks ~/Notebooks
