Bug on line 111-115 in diode.py?

[jisonZ]

    im_fname = osp.join(self.data_root, '{}.png'.format(im))
    de_fname = osp.join(self.data_root, '{}_depth.npy'.format(im))
    de_mask_fname = osp.join(self.data_root, '{}_depth_mask.npy'.format(im))

    im = np.array(Image.open(osp.join(self.data_root, im_fname)))

on the last line the im_fname is joined twice with self.data_root
