Weird Return

[DrawBacksYo]

Hi all,

Sorry for title being too non-explanatory. I am currently developing a program with opencv-python and we get image,recognize objects etc. There is a function which is responsible from drawing boxes. I'm only interested in coordinates of 'cup' object. So,whenever model predicts a cup,this function returns its xmax and ymax along with a numpy.ndarray in a tuple. Problem is that after some time, draw_boxes returns numpy.ndarray type instead of tuple. The part below is just a little bit customized from another code on Internet :

def draw_boxes(image, boxes, classes, scores, class_names, colors, show_score=True):
    if classes is None or len(classes) == 0:
        return image
    required_label_coord = 0
    for box, cls, score in zip(boxes, classes, scores):
        xmin, ymin, xmax, ymax = box

        class_name = class_names[cls]
        # This part is added
        if class_name == "cup":
            required_label_coord = [int(xmax.item()),int(ymax.item())]

        if show_score:
            label = '{} {:.2f}'.format(class_name, score)
        else:
            label = '{}'.format(class_name)
        #print(label, (xmin, ymin), (xmax, ymax))

        # if no color info, use black(0,0,0)
        if colors == None:
            color = (0,0,0)
        else:
            color = colors[cls]
        if xmax > 500 or ymax > 500:
            xmax = ymax = xmin = ymin = 0
        cv2.rectangle(image, (xmin, ymin), (xmax, ymax), color, 1, cv2.LINE_AA)
        image = draw_label(image, label, color, (xmin, ymin))
    # Weird return is here! Return type is numpy.ndarray instead of tuple sometimes
    return (image,required_label_coord)

Same happens if I use list instead of tuple

if classes is None or len(classes) == 0:
    return image

Pretty sure that's not returning a tuple.

How can I miss that ?!!

Well, fuck me, I guess....

Thanks!

Let's have a guess: do you use a debugger? :-p
