The criterion to satisfy for providing the new shape is that 'The new shape should be compatible with the original shape'. numpy allow us to give one of new shape parameter as -1 (eg: (2,-1) or (-1,3) but not (-1, -1)). It simply means that it is an unknown dimension and we want numpy to figure it out.
