 Run the program via SSH. Ensure no other programs are running (including the startup application launcher).
 Steps:
 * Connect MaixVision to the device to close the Launcher, or use SSH to `kill` the `launcher_daemon`.

 ### 运行
 
 通过 ssh 终端运行程序。注意要保证没有程序正在运行（包括开机的应用选择界面(Launcher)）。
 具体方法：
 * MaixVision 连接设备，这会让 Launcher 退出。也可以在 ssh 终端手动`kill` `launcher_daemon`程序。（**重要!!**）
