Error“ValueError:使用序列设置数组元素。”

Question

我试图编译这个使用opencv库的代码

criteria = (cv2.TERM_CRITERIA_EPS + cv2.TERM_CRITERIA_MAX_ITER, 10, 1.0)
XX=[]

for i in range(len(K_points)):
      XX.append(K_points[i])
ret,label,center=cv2.kmeans(np.float32(XX),len(K_points),None,criteria,10,cv2.KMEANS_RANDOM_CENTERS)

错误：

ValueError: setting an array element with a sequence.
