Description

Mistake is that findContours is unpacked just to contours and hierarchy. Though in version 3 it is unpacked to image, contours and hierarchy.

In tutorials now:
contours, hierarchy = cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)

Fixed:
_, contours, hierarchy = cv2.findContours(thresh,cv2.RETR_TREE,cv2.CHAIN_APPROX_SIMPLE)

Bus is here http://docs.opencv.org/trunk/doc/py_tutorials/py_imgproc/py_contours/py_contours_begin/py_contours_begin.html#contours-getting-started
