reorg operator used in Yolo v2.
The equation is: C2 = C1/blocksize * blocksize, W2 = W1 ∗ blocksize + offset % blocksize, H2 = H1 ∗ blocksize + offset / blocksize,
Reshape Input(X) into the shape according to Attr(blocksize). The
data in Input(X) are unchanged.
Examples:
1. Given a 4-D tensor Input(X) with a shape [128, 2048, 26, 26], and the blocksize is 2, the reorg operator will transform Input(X)
into a 4-D tensor with shape [128, 2048, 13, 13] and leaving Input(X)'s data unchanged.

Gives a blocksize to space_to_depth the input LoDtensor with Layout: [batch, channel, height, width]
This op rearranges blocks of spatial data, into depth. More specifically, this op outputs a copy of the
input LoDtensor where values from the height and width dimensions are moved to the channel dimension.
The attr blocksize indicates the input block size.
space_to_depth will reorgnize the elements of input with shape[batch, channel, height, width] according
to blocksize to construct output with shape [batch, channel * blocksize * blocksize, height/blocksize, width/blocksize]:
space_to_depth is used to This operation is useful for resizing the activations between convolutions
(but keeping all data)
- Non-overlapping blocks of size block_size x block size are rearranged into depth at each location.
- The depth of the output tensor is block_size * block_size * input channel
- The Y, X coordinates within each block of the input become the high order component of the output channel index
- channel should be divisible by square of blocksize
- height, width should be divsible by blocksize
Args:
x(variable): The input LoDtensor.
blocksize(variable): The blocksize to select the element on each feature map should be > 2
Returns:
Variable: The output LoDtensor.
Raises:
TypeError: blocksize type must be a long.
Examples:
.. code-block:: python
data = fluid.layers.data(
name='data', shape=[1, 4, 2, 2], dtype='float32')
space_to_depthed = fluid.layers.space_to_depth(
x=data, blocksize=2)
