请问各位大佬有见过这种错误嘛？？各种地方都搜不到。。

源代码在这里： https://github.com/danforthcenter/plantcv/blob/master/plantcv/plantcv/morphology/segment_euclidean_length.py

for i, cnt in enumerate(objects):
        # Store coordinates for labels
        x_list.append(objects[i][0][0][0])
        y_list.append(objects[i][0][0][1])

        # Draw segments one by one to group segment tips together
        finding_tips_img = np.zeros(segmented_img.shape[:2], np.uint8)
        cv2.drawContours(finding_tips_img, objects, i, (255, 255, 255), 1, lineType=8)
        segment_tips = find_tips(finding_tips_img)
        tip_objects, tip_hierarchies = find_objects(segment_tips, segment_tips)
        points = []
        if not len(tip_objects) == 2:
            fatal_error("Too many tips found per segment, try pruning again")
        for t in tip_objects:
            # Gather pairs of coordinates
            x, y = t.ravel()
            coord = (x, y)
            points.append(coord)

你要看你调用的参数是否正确
