lxxstc / dlib and face_recognition on raspberry pi.md
Created December 31, 2017 19:21 — forked from ageitgey/dlib and face_recognition on raspberry pi.md

Install dlib and face_recognition on a Raspberry Pi

Instructions tested with a Raspberry Pi 2 with an 8GB memory card. Probably also works fine on a Raspberry Pi 3.

Steps

Download the latest Raspbian Jessie Light image. Earlier versions of Raspbian won't work.

Write it to a memory card using Etcher, put the memory card in the RPi and boot it up.

安装BLAS/LAPACK

不必按照INSTALL.md里面的编译安装方法，只要安装源里的包即可

$ sudo apt install libopenblas-dev
$ sudo apt install liblapack
$ sudo apt install swig

CentOS7

如何访问百度内网的链接

环境

  • 外网跳板: 192.241.238.106
  • 百度机和端口：cq02-vs-hotel-test02.cq02.baidu.com:8085
  • 本机：127.0.0.1

步骤

  • 从百度内网建立一个远端转发端口
 ssh -R 2123:cq02-vs-hotel-test02.cq02.baidu.com:8085 shrimp@192.241.238.106  -p80

创建一个:

$ time dd if=/dev/zero of=test bs=128k count=1512 oflag=dsync

用tcpdump以文本形式查看报文内容:

$ sudo tcpdump -p  -i eth0 -s 0 -l -w - dst port 6666 and dst host l-mem1.f.cn1.qunar.com | strings | grep set
