        thickness = int(pointsarray[1,0]) - int(pointsarray[0,0])  #here is the error
        print(thickness)              
        cv2.line(img, (cx, cy), (cx+50, cy), (0,0,255), 1)
        cv2.putText(img, 'Thickness : '+str(thickness),(x-20, y-10), font, 0.4,(0,0,0),1,cv2.LINE_AA)

cv2.imshow('img', img)

The following error occurs:

thickness = int(pointsarray[1,0]) - int(pointsarray[0,0]) IndexError: too many indices for array

Answer 1

if you have 2D array try this:

thickness = int(pointsarray[1][0]) - int(pointsarray[0][0])

list object needs to be accessed separately, or you can use numpy arrays
