我在下面的代码中得到了一个我不理解的错误Python ';元组';对象没有属性';夹子';,python,opencv,image-processing,tuples,Python,Opencv,Image Processing,Tuples,我在下面的代码中得到了一个我不理解的错误 imgColor = cv2.imread(fileName, cv2.IMREAD_COLOR) imgColor1= cv2.cvtColor(imgColor, cv2.COLOR_BGR2HSV) ret,thresh1 = cv2.threshold(imgColor1,127,255,cv2.THRESH_BINARY) ret,thresh2 = cv2.threshold(imgColor1,127,255,cv2.THRESH_BIN

请解释为什么会发生这种情况,以及我如何解决这个问题。如果有人能对此问题提供任何建议,那就太好了。您正在传递给cv2\u imshow cv2.threshold的结果,它是一个元组。您需要修改对的调用,例如
cv2\u imshow(阈值图像[阈值][1])
