* ## Space2Batch
|
|
*
|
|
* This operation divides "spatial" dimensions [1, ..., M] of the input into a grid
|
|
* of blocks of shape **block_size**, and interleaves these blocks with the "batch"
|
|
* dimension (0) such that in the output, the spatial dimensions [1, ..., M] correspond
|
|
* to the position within the grid, and the batch dimension combines both the position
|
|
* within a spatial block and the original batch position. Prior to division into blocks,
|
|
* the spatial dimensions of the input are optionally zero padded according to paddings.
|
|
* This is the reverse transformation of Batch2Space.
|
|
*
|
|
* - pad : the paddings for each spatial dimension of the input tensor.
