NameError: name 'gray' is not defined

When I try to run aruco_tracker.py I get
[ WARN:0] global /io/opencv/modules/videoio/src/cap_v4l.cpp (887) open VIDEOIO(V4L2:/dev/video1): can't open camera by index Traceback (most recent call last): File "aruco_tracker.py", line 55, in <module> ret, mtx, dist, rvecs, tvecs = cv2.calibrateCamera(objpoints, imgpoints, gray.shape[::-1],None,None) NameError: name 'gray' is not defined
I'm new to python and I could really use this code, can anyone help me fix this?
Just change the directory
images = glob.glob('calib_images/checkerboard/*.jpg')
