out (Sequence[Tensor], optional, keyword-
        only) -- the GPU tensors to store output results. Sizes of
        these tensors must match that of "tensor", except for "dim",
        where the total size must sum to "tensor.size(dim)".

Note:
 Exactly one of "devices" and "out" must be specified. When "out"
 is specified, "chunk_sizes" must not be specified and will be
 inferred from sizes of "out".

Returns:
      * If "devices" is specified,
           a tuple containing chunks of "tensor", placed on "devices".
  * If "out" is specified,
       a tuple containing "out" tensors, each containing a chunk
       of "tensor".
