3.27.2. Manually install face_recognition

1) First create a new ~/.pip directory, then add the pip.conf configuration file, and set the mirror source of pip to Tsinghua source in it, the commands to be executed are as follows

orangepi@orangepi:~$ mkdir -p ~/.pip
orangepi@orangepi:~$ cat <<EOF > ~/.pip/pip.conf
[global]
timeout = 6000
index-url = https://pypi.tuna.tsinghua.edu.cn/simple
trusted-host = pypi.tuna.tsinghua.edu.cn
EOF

2) Then install dependencies

orangepi@orangepi:~$ sudo apt update
orangepi@orangepi:~$ sudo apt install -y python3-pip libopencv-dev \
python3-opencv imagemagick python3-scipy python3-setuptools python3-wheel \
python3-dev cmake python3-testresources

3) Then update pip3

orangepi@orangepi:~$ python3 -m pip install -U pip setuptools wheel

4) Before installing face_recognition, you first need to install the dlib library. Since the compilation and installation of the dlib library on the development board is relatively slow, I saved a compiled dlib whl file on gitee, and you can install it directly after downloading.

The download address of the dlib whl file is as follows https://gitee.com/leeboby/python_whl

a. First download the python_whl warehouse to the Linux system of the development board

orangepi@orangepi:~$ git clone --depth=1 https://gitee.com/leeboby/python_whl

b. In the python_whl folder, you can see that there are multiple versions of dlib installation packages. The Linux systems corresponding to different versions of dlib are as follows

Ubuntu20.04 dlib-19.24.0-cp38-cp38-linux_aarch64.whl
Ubuntu22.04 dlib-19.24.0-cp310-cp310-linux_aarch64.whl
Debian11 dlib-19.24.0-cp39-cp39-linux_aarch64.whl

c. Then you can start installing dlib, the command is as follows a) Ubuntu20.04

orangepi@orangepi:~$ cd python_whl
orangepi@orangepi:~/python_whl$ python3 -m pip install dlib-19.24.0-cp38-cp38-linux_aarch64.whl

b) Ubuntu22.04

orangepi@orangepi:~$ cd python_whl
orangepi@orangepi:~/python_whl$ python3 -m pip install dlib-19.24.0-cp310-cp310-linux_aarch64.whl

c) Debian11

orangepi@orangepi:~$ cd python_whl
orangepi@orangepi:~/python_whl$ python3 -m pip install dlib-19.24.0-cp39-cp39-linux_aarch64.whl

d. After installation, if the version number of dlib can be printed normally by using the following command, it means that dlib is installed correctly

orangepi@orangepi:~/python_whl$ python3 -c "import dlib; print(dlib.__version__)" \ 19.24.0

5) Then install face_recognition_models-0.3.0-py2.py3-none-any.whl

orangepi@orangepi:~/python_whl$ python3 -m pip install face_recognition_models-0.3.0-py2.py3-none-any.whl

6) Then install face_recognition

orangepi@orangepi:~$ python3 -m pip install face_recognition

7) Then you need to reopen a terminal to find and run the two commands face_detection and face_recognition

a. The face_recognition command is used to recognize whose face is in a single image or a folder of images.

b. The face_detection command is used to locate the face in a single picture or a picture folder

orangepi@orangepi:~$ which face_detection
/usr/local/bin/face_detection
orangepi@orangepi:~$ which face_recognition
/usr/local/bin/face_recognition

If you can't find the above two commands after reopening the terminal, please try to manually import environment variables, and then test again

orangepi@orangepi:~$ export PATH=/home/orangepi/.local/bin:$PATH
