<li><p>'''Android''' '''source code'''： : Save on Google Drive</p></li><li><p>'''Linux''' '''source code'''：Save :Save on Github</p></li><li><p>'''Android''' '''source code'''：Save :Save on Google Drive</p></li><li><p>'''Ubuntu''' '''source code'''：Save :Save on Google Drive</p></li><li><p>'''Debian''' '''source code'''：Save :Save on Google Drive</p></li><li><p>'''User Manual and Schematic：Schematic:'''Chip-related data sheets will also be placed here</p></li><li><p>'''Official tool：tool:'''It mainly includes the software that needs to be used during the use of the development board</p></li></ol>

<li><p>'''The model of the development board'''：Both :Both are '''orangepizero3'''. The model names of different development boards are generally different. Before burning the image, please make sure that the model name of the selected image matches the development board.</p></li><li><p>'''Version number'''：For :For example, '''1.x.x''', this version number will increase with the update of the image function, and the last number of the version number of the Linux image on the development board is an even number.</p></li><li><p>'''Types of Linux distributions'''： : '''Ubuntu''' and '''Debian''' are currently supported. Since Ubuntu is derived from Debian, there is not much difference between the two systems in terms of usage. However, there are still some differences in the default configuration of some software and the use of commands. In addition, both Ubuntu and Debian have their own software warehouses supported by maintenance, and there are also some differences in the supported and installable software packages. These need to be experienced in person to have a deeper understanding. For more details, you can refer to the official documentation provided by Ubuntu and Debian.</p></li><li><p>'''Release code name'''： : Used to distinguish between different versions of a specific Linux distribution such as Ubuntu or Debian. Among them, both '''focal''' and '''jammy''' are Ubuntu distributions, focal means Ubuntu20.04, and jammy means Ubuntu22.04. The biggest difference between different versions is that the software in the software warehouse maintained by the new version of Ubuntu system is much better than that of the old version of Ubuntu system. The ones in it should be new, such as Python and GCC compilation tool chains. '''bullseye''' is the specific version code of Debian, bullseye means Debian11, and bookworm means Debian12.</p></li><li><p>'''Server or Desktop'''：It :It is used to indicate whether the system has a desktop environment. If it is server, it means that the system does not have a desktop environment. The storage space and resources occupied by the image are relatively small, and the command line is mainly used to operate and control the system. If it is '''desktop_xfce''', it means that the system is installed with the XFCE desktop environment by default. The storage space and resources occupied by the image are relatively large. You can connect the monitor, mouse and keyboard to operate the system through the interface. Of course, the desktop version of the system can also be operated through the command line like the server version of the system.</p></li><li><p>'''Kernel version'''：Used :Used to indicate the version number of the linux kernel, currently supports '''linux5.4''' and '''linux6.1.'''</p></li></ol>

<li><p>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：follows:</p>

<li><p>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：follows:</p>

<li><p>In the python_whl folder, you can see that there are multiple &gt; versions of dlib installation packages. The Linux systems &gt; corresponding to different versions of dlib are as follows：follows:</p></li></ol>
