Swap memory
OpenCV needs a lot of memory to compile. The latest versions want to see a minimum of 6.5 GB of memory before building. Your swap space is limited to 2048 MByte by default. To exceed this 2048 MByte limit, you will need to increase this maximum in the /sbin/dphys-swapfile.

Копиране на директорията на потребител pi в Raspberry OS с rsync отдалечено:
rsync -chavzP --stats pi@remote.host:/home/pi /path/to/local/storageкъдето remote.host е IP адресът на Raspberry Pi, а /path/to/local/storage локалната директория, където ще бъдат копирани данните.
Конфигуриране на WiFi мрежата в Raspberry OS:
Отворете с nano или друг редактор следния файл:
sudo nano /etc/network/interfacesВъведете във файла следната конфигурация:
auto lo iface lo inet loopback iface eth0 inet dhcp allow-hotplug wlan0 auto wlan0 iface wlan0 inet dhcp wpa-ssid "Your Network SSID" wpa-psk "Your Password"
където Your Network SSID е името на вашата WiFi точка за достъп, а Your Password е паролата на точката за достъп.
Рестартирайте мрежовата услуга в Raspberry OS:
sudo service networking reload
