How to read and convert the image to match the one on database to mark the attendance

[Hojeah2663]

Now I have this specific error at which the image from the cam can’t be converted to gray image so it brings this error

File "AMS_Run.py", line 347, in Fillattendances
gray = cv2.cvtColor(im, cv2.COLOR_BGR2GRAY)
cv2.error: OpenCV(4.2.0) C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:182: error: (-215:Assertion failed) !_src.empty() in function 'cv::cvtColor'
Please help

It's not getting frame, that's the error.
