人臉識別并不是什么高大上的東西，入門人臉識別，內容包括硬件配置，環(huán)境搭載，代碼詳解，程序部署，傳送門：樹莓派4b之初學者入門人臉識別
硬件：Raspberry Pi 4B
系統(tǒng)：Ubuntu 19.10 (Eoan Ermine) for IOT
官網：https://ubuntu.com/download/iot/raspberry-pi
下載通道：
Ubuntu Server 19.10 for Raspberry Pi 4 64-bit：ubuntu-19.10.1-preinstalled-server-arm64+raspi3.img.xz
Ubuntu Server 19.10 for Raspberry Pi 4 32-bit：ubuntu-19.10.1-preinstalled-server-armhf+raspi3.img.xz
配置步驟
1. 下載系統(tǒng)鏡像
http://cdimage.ubuntu.com/releases/19.10/release/ubuntu-19.10-preinstalled-server-arm64+raspi3.img.xz
2. 燒錄至SD卡進行系統(tǒng)安裝
3. 系統(tǒng)登陸
默認賬號：ubuntu 默認密碼：ubuntu
4. 更換鏡像源
4.1 備份 apt 源文件
sudo cp -p /etc/apt/sources.list /etc/apt/sources.list.bak
如果出錯的時候，需要恢復源文件的話。操作如下：
rm -rf /etc/apt/sources.list
sudo cp -p /etc/apt/sources.list.bak /etc/apt/sources.list
4.2 編輯 apt 源文件，更新為國內鏡像源（注意：路徑節(jié)點不是 ubuntu，而是 ubuntu-ports）
sudo nano /etc/apt/sources.list
