unflatten
[common]
fun unflatten(input: Tensor, dim: Long, sizes: LongArray): Tensor
unflatten(input: Tensor, dim: Long, sizes: LongArray): the unflatten operator. Split the dim at dim into sizes, the inverse of flatten. The product of sizes must equal that dim's extent. Returns a view sharing storage when the layout permits; copies otherwise.
