Language: Python
Intended purpose: using face_recognition library and OpenCV library computer camera real-time face recognition
Problems: real-time face detection functions such as there is no problem, but every time I open the program will be open in addition to the camera images of multiple gray small window, that is to say every time open the program, in addition to real-time camera detection images will also have more than one gray, together without any display window is opened,
