aliran tensor:: operasi:: BatchToSpace
#include <array_ops.h> BatchToSpace untuk tensor 4-D tipe T.
Ringkasan
Ini adalah versi lawas dari BatchToSpaceND yang lebih umum.
Menyusun ulang (mengubah) data dari kumpulan menjadi blok data spasial, diikuti dengan pemotongan. Ini adalah transformasi kebalikan dari SpaceToBatch. Lebih khusus lagi, operasi ini menghasilkan salinan tensor masukan di mana nilai dari dimensi batch dipindahkan dalam blok spasial ke dimensi height dan width , diikuti dengan pemotongan sepanjang dimensi height dan width .
Argumen:
- ruang lingkup: Objek Lingkup
- masukan: tensor 4-D dengan bentuk
[batch*block_size*block_size, height_pad/block_size, width_pad/block_size, depth] . Perhatikan bahwa ukuran kumpulan tensor masukan harus habis dibagi block_size * block_size . - tanaman: tensor 2-D bilangan bulat non-negatif dengan bentuk
[2, 2] . Ini menentukan berapa banyak elemen yang akan dipotong dari hasil antara di seluruh dimensi spasial sebagai berikut: crops = [[crop_top, crop_bottom], [crop_left, crop_right]]
Pengembalian:
-
Output : 4-D dengan bentuk [batch, height, width, depth] , dimana: height = height_pad - crop_top - crop_bottom
width = width_pad - crop_left - crop_right
block_size attr harus lebih besar dari satu. Ini menunjukkan ukuran blok.

This is the reverse transformation of SpaceToBatch. More specifically, this op outputs a copy of the input tensor where values from the `batch` dimension are moved in spatial blocks to the `height` and `width` dimensions, followed by cropping along the `height` and `width` dimensions.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- input: 4-D tensor with shape `[batch*block_size*block_size, height_pad/block_size, width_pad/block_size, depth]`. Note that the batch size of the input tensor must be divisible by `block_size * block_size`.\n- crops: 2-D tensor of non-negative integers with shape `[2, 2]`. It specifies how many elements to crop from the intermediate result across the spatial dimensions as follows: \n\n ```scdoc\n crops = [[crop_top, crop_bottom], [crop_left, crop_right]]\n ```\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 4-D with shape `[batch, height, width, depth]`, where: \n\n ```scdoc\n height = height_pad - crop_top - crop_bottom\n width = width_pad - crop_left - crop_right\n ```\n\n\u003cbr /\u003e\n\nThe attr `block_size` must be greater than one.
