1. 安装过程基本遵循以下步骤
电脑端环境配置 - OriginBot智能机器人开源套件
需要注意以下两点：
1> 由于深度学习需要的包和镜像体积都比较大，所以虚拟机硬盘大小建议120GB
2> 虚拟机的网络适配器应该设置为桥接模式，如果使用NAT模式，会导致两个问题:
a. 不能接收到无人车发布的话题
b. docker pull 镜像的时候速度极慢
2. 在执行以下语句时，可能会报错：
thomas@J-35:~$ sudo curl -sSL https://raw.githubusercontent.com/ros/rosdistro/master/ros.key -o /usr/share/keyrings/ros-archive-keyring.gpg
curl: (7) Failed to connect to raw.githubusercontent.com port 443 after 11 ms: Connection refused
解决办法是修改 /etc/hosts文件，并添加以下内容
185.199.111.133 raw.githubusercontent.com如果111也连接失败，可以试试108,109,110
3. 安装pytorch，需要先安装pip3
sudo apt install python3-pip
pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cpu4. 安装Docker
安装命令如下
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
docker --version执行 docker --version 显示安装完成
thomas@J-35:~/dev_ws$ curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

安装完成后，通过如下命令，下载后续模型转换的工具链和docker镜像
- 下载AI工具链OE包（6.1GB）
wget -c ftp://vrftp.horizon.ai/Open_Explorer_gcc_9.3.0/2.3.3/horizon_xj3_open_explorer_v2.3.3_20220727.tar.gz
- 下载AI工具链docker（14.8GB）
wget -c ftp://vrftp.horizon.ai/Open_Explorer_gcc_9.3.0/2.3.3/x3pi_toolchain/ai_toolchain_2.3.3.tar.gz
安装 onnx, onnxruntime
pip install onnx
pip install onnxruntime
完成Docker环境安装后，需要将无root权限的用户添加到Docker用户组中。参考如下命令：
sudo groupadd docker
sudo gpasswd -a ${USER} docker # ${USER} 替换成用户名
sudo systemctl restart docker
设置docker 镜像加速
Docker 镜像加速 | 菜鸟教程
阿里云镜像获取地址：阿里云登录 - 欢迎登录阿里云，安全稳定的云计算服务平台
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{"registry-mirrors": ["https://需要替换.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker检查加速器是否生效
thomas@J-35:~$ sudo docker infoRegistry Mirrors:https://owzy8hoh.mirror.aliyuncs.com/
如果想要顺利下载，还需要设置DNS，
sudo gedit /etc/resolv.conf在打开的 /etc/resolv.conf 文件中，修改如下
# nameserver 127.0.0.53
# options edns0 trust-ad
# search localdomainnameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 223.5.5.5
接下来可以拉取镜像了，
sudo docker pull openexplorer/ai_toolchain_centos_7_xj3:v2.3.3由于镜像文件非常大，需要的时间会很长
thomas@J-35:~$ sudo docker pull openexplorer/ai_toolchain_centos_7_xj3:v2.3.3
