def unpack_vectors(
        packed_vectors:  NDArray,            # shape=(d,)+stack_shape+(N,)
        unpacking_shape: typ.Sequence[int],  # (N0,...,N(d-1))
) -> typ.Tuple[NDArray, ...]:                # len=d, ith elm_shape=stack_shape+(Ni,)

Slice a packed supercore-shaped tensor back into a tuple of (ragged-length) vectors.

Parameters:

• packed_vectors (NDArray)

• unpacking_shape (t3toolbox.backend.common.typ.Sequence[int])

Return type:

t3toolbox.backend.common.typ.Tuple[NDArray, Ellipsis]
