You need to enable opencv module. For example, you can enable it for console by the command: echo "extension=opencv.so" > /etc/php/7.2/cli/conf.d/opencv.ini

You need to change it for your os, version of php and your web server. For example: echo "extension=opencv.so" > /etc/php/7.2/fpm/conf.d/opencv.ini echo "extension=opencv.so" > /etc/php/7.2/apache2/conf.d/opencv.ini
