+// SpaceToBatch for 4-D tensors of type T.
+//
+// This is a legacy version of the more general SpaceToBatchND.
+//
+// Zero-pads and then rearranges (permutes) blocks of spatial data into batch.
+// More specifically, this op outputs a copy of the input tensor where values from
+// the `height` and `width` dimensions are moved to the `batch` dimension. After
+// the zero-padding, both `height` and `width` of the input must be divisible by the
+// block size.
+//
+// Arguments:
+//	input: 4-D with shape `[batch, height, width, depth]`.
+//	paddings: 2-D tensor of non-negative integers with shape `[2, 2]`. It specifies
+//   the padding of the input with zeros across the spatial dimensions as follows:
+//
+//       paddings = [[pad_top, pad_bottom], [pad_left, pad_right]]
+//
+//   The effective spatial dimensions of the zero-padded input tensor will be:
+//
+//       height_pad = pad_top + height + pad_bottom
+//       width_pad = pad_left + width + pad_right
+//
+// The attr `block_size` must be greater than one. It indicates the block size.
+//
+//   * Non-overlapping blocks of size `block_size x block size` in the height and
+//     width dimensions are rearranged into the batch dimension at each location.
+//   * The batch of the output tensor is `batch * block_size * block_size`.
+//   * Both height_pad and width_pad must be divisible by block_size.
+//
+// The shape of the output will be:
+//
+//     [batch*block_size*block_size, height_pad/block_size, width_pad/block_size,
+//      depth]
+//
+// Some examples:
+//
+// (1) For the following input of shape `[1, 2, 2, 1]` and block_size of 2:
+//
+// ```
+// x = [[[[1], [2]], [[3], [4]]]]
+// ```
+//
+// The output tensor has shape `[4, 1, 1, 1]` and value:
+//
+// ```
+// [[[[1]]], [[[2]]], [[[3]]], [[[4]]]]
+// ```
+//
+// (2) For the following input of shape `[1, 2, 2, 3]` and block_size of 2:
+//
+// ```
+// x = [[[[1, 2, 3], [4, 5, 6]],
+//       [[7, 8, 9], [10, 11, 12]]]]
+// ```
+//
+// The output tensor has shape `[4, 1, 1, 3]` and value:

+// This operation divides "spatial" dimensions `[1, ..., M]` of the input into a
+// grid of blocks of shape `block_shape`, 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`.  See below for a
+// precise description.
+//
+// Arguments:
+//	input: N-D with shape `input_shape = [batch] + spatial_shape + remaining_shape`,
+// where spatial_shape has `M` dimensions.
+//	block_shape: 1-D with shape `[M]`, all values must be >= 1.
+//	paddings: 2-D with shape `[M, 2]`, all values must be >= 0.
+//   `paddings[i] = [pad_start, pad_end]` specifies the padding for input dimension
+//   `i + 1`, which corresponds to spatial dimension `i`.  It is required that
+//   `block_shape[i]` divides `input_shape[i + 1] + pad_start + pad_end`.
+//
+// This operation is equivalent to the following steps:
+//
+// 1. Zero-pad the start and end of dimensions `[1, ..., M]` of the
+//    input according to `paddings` to produce `padded` of shape `padded_shape`.
+//
+// 2. Reshape `padded` to `reshaped_padded` of shape:
+//
+//      [batch] +
+//      [padded_shape[1] / block_shape[0],
+//        block_shape[0],
+//       ...,
+//       padded_shape[M] / block_shape[M-1],
+//       block_shape[M-1]] +
+//      remaining_shape
+//
+// 3. Permute dimensions of `reshaped_padded` to produce
+//    `permuted_reshaped_padded` of shape:
+//
+//      block_shape +
+//      [batch] +
+//      [padded_shape[1] / block_shape[0],
+//       ...,
+//       padded_shape[M] / block_shape[M-1]] +
+//      remaining_shape
+//
+// 4. Reshape `permuted_reshaped_padded` to flatten `block_shape` into the batch
+//    dimension, producing an output tensor of shape:
+//
+//      [batch * prod(block_shape)] +
+//      [padded_shape[1] / block_shape[0],
+//       ...,
+//       padded_shape[M] / block_shape[M-1]] +

-//       block_shape[M-1]] +
-//      remaining_shape

-//      remaining_shape
-//
-// 4. Reshape `permuted_reshaped_padded` to flatten `block_shape` into the batch

-//	input: 4-D with shape `[batch, height, width, depth]`.
-//	paddings: 2-D tensor of non-negative integers with shape `[2, 2]`. It specifies
-//   the padding of the input with zeros across the spatial dimensions as follows:
-//
-//       paddings = [[pad_top, pad_bottom], [pad_left, pad_right]]
-//
-//   The effective spatial dimensions of the zero-padded input tensor will be:
-//
-//       height_pad = pad_top + height + pad_bottom
-//       width_pad = pad_left + width + pad_right
-//
-// The attr `block_size` must be greater than one. It indicates the block size.
-//
-//   * Non-overlapping blocks of size `block_size x block size` in the height and
-//     width dimensions are rearranged into the batch dimension at each location.
-//   * The batch of the output tensor is `batch * block_size * block_size`.
-//   * Both height_pad and width_pad must be divisible by block_size.
-//
-// The shape of the output will be:
-//
-//     [batch*block_size*block_size, height_pad/block_size, width_pad/block_size,
-//      depth]
-//
-// Some examples:
-//
-// (1) For the following input of shape `[1, 2, 2, 1]` and block_size of 2:
-//
-// ```
-// x = [[[[1], [2]], [[3], [4]]]]
-// ```
-//
-// The output tensor has shape `[4, 1, 1, 1]` and value:
-//
-// ```
-// [[[[1]]], [[[2]]], [[[3]]], [[[4]]]]
-// ```
-//
-// (2) For the following input of shape `[1, 2, 2, 3]` and block_size of 2:
-//
-// ```
-// x = [[[[1, 2, 3], [4, 5, 6]],
-//       [[7, 8, 9], [10, 11, 12]]]]
-// ```
-//
-// The output tensor has shape `[4, 1, 1, 3]` and value:
-//
-// ```
-// [[[1, 2, 3]], [[4, 5, 6]], [[7, 8, 9]], [[10, 11, 12]]]
-// ```
-//
-// (3) For the following input of shape `[1, 4, 4, 1]` and block_size of 2:
-//
-// ```
-// x = [[[[1],   [2],  [3],  [4]],
-//       [[5],   [6],  [7],  [8]],
-//       [[9],  [10], [11],  [12]],
-//       [[13], [14], [15],  [16]]]]
-// ```
-//
-// The output tensor has shape `[4, 2, 2, 1]` and value:
-//
-// ```
-// x = [[[[1], [3]], [[9], [11]]],
-//      [[[2], [4]], [[10], [12]]],
-//      [[[5], [7]], [[13], [15]]],
-//      [[[6], [8]], [[14], [16]]]]
-// ```
-//
-// (4) For the following input of shape `[2, 2, 4, 1]` and block_size of 2:
-//
-// ```
-// x = [[[[1],   [2],  [3],  [4]],
-//       [[5],   [6],  [7],  [8]]],
-//      [[[9],  [10], [11],  [12]],
-//       [[13], [14], [15],  [16]]]]
-// ```
-//
-// The output tensor has shape `[8, 1, 2, 1]` and value:
-//
-// ```
-// x = [[[[1], [3]]], [[[9], [11]]], [[[2], [4]]], [[[10], [12]]],
-//      [[[5], [7]]], [[[13], [15]]], [[[6], [8]]], [[[14], [16]]]]
-// ```

-// Among others, this operation is useful for reducing atrous convolution into
