According to the `jupyter` notebook, it should instead contain a 4-tuple `(x1, y1, x2, y2)` of the location of the sign in the original, larger image.\n\nWithin the `jupyter` notebook, running `train['coords'] == train['sizes']` yields\n```\narray([[ True,  True],\n       [ True,  True],\n       [ True,  True],\n       ..., \n       [ True,  True],\n       [ True,  True],\n       [ True,  True]], dtype=bool)\n```"}}
