old no data and attempting to access some properties, like their shape,
    will throw a runtime error. The only operations that can be performed on a uninitialized
    parameter are changing its datatype, moving it to a different device and
    converting it to a regular :class:`torch.Tensor`.

    The default device or dtype to use when the buffer is materialized can be set
    during construction using e.g. ``device='cuda'``.
