什么原因TypeError: callback() takes 0 positional arguments but 1 was given

不能转换颜色
import cv2

def callback():
     pass

cv2.namedWindow('color',cv2.WINDOW_NORMAL)

img = cv2.imread('./rc.jpeg')

colorspaces = [cv2.COLOR_BGR2RGBA,cv2.COLOR_BGR2BGRA,cv2.COLOR_BGR2GRAY,cv2.COLOR_BGR2HSV_FULL,cv2.COLOR_BGR2YUV]
cv2.createTrackbar('curcolor','color',0 ,len(colorspaces),callback)

while True:
    index = cv2.getTrackbarPos('curcolor','color')

    #颜色空间转换api
    cvt_img = cv2.cvtColor(img, colorspaces[index])

    cv2.imshow('color',img)
    key = cv2.waitKey(10)
    print(key)
    if key & 0xFF == ord('q'):
      break
cv2.destroyAllWindows()
