fluxo tensor:: ops:: FusedResizeAndPadConv2D
#include <nn_ops.h> Executa um redimensionamento e preenchimento como pré-processo durante uma convolução.
Resumo
Muitas vezes é possível fazer transformações espaciais de forma mais eficiente como parte do estágio de empacotamento de uma convolução, portanto, esta operação permite uma implementação otimizada onde esses estágios são fundidos. Isso evita a necessidade de escrever os resultados intermediários como tensores inteiros, reduzindo a pressão da memória, e podemos obter alguns ganhos de latência mesclando os cálculos de transformação. O atributo data_format para Conv2D não é suportado por esta operação e o padrão é a ordem 'NHWC'. Internamente, esta operação usa um único buffer de rascunho por gráfico, o que significa que será bloqueado se várias versões estiverem sendo executadas em paralelo. Isso ocorre porque esse operador é principalmente uma otimização para minimizar o uso de memória.
Argumentos:
- escopo: um objeto Escopo
- entrada: 4-D com forma
[batch, in_height, in_width, in_channels] . - size: Um tensor int32 1-D de 2 elementos:
new_height, new_width . O novo tamanho das imagens. - preenchimentos: uma matriz de duas colunas especificando os tamanhos de preenchimento. O número de linhas deve ser igual à classificação de
input . - filtro: 4-D com forma
[filter_height, filter_width, in_channels, out_channels] . - passadas: 1-D de comprimento 4. A passada da janela deslizante para cada dimensão de
input . Deve estar na mesma ordem que a dimensão especificada com formato. - preenchimento: O tipo de algoritmo de preenchimento a ser usado.
Atributos opcionais (veja Attrs ):
- resize_align_corners: Se verdadeiro, os centros dos 4 pixels dos cantos dos tensores de entrada e saída são alinhados, preservando os valores nos pixels dos cantos. O padrão é falso.

This prevents the need to write out the intermediate results as whole tensors, reducing memory pressure, and we can get some latency gains by merging the transformation calculations. The data_format attribute for [Conv2D](/versions/r1.15/api_docs/cc/class/tensorflow/ops/conv2-d#classtensorflow_1_1ops_1_1_conv2_d) isn't supported by this op, and defaults to 'NHWC' order. Internally this op uses a single per-graph scratch buffer, which means that it will block if multiple versions are being run in parallel. This is because this operator is primarily an optimization to minimize memory usage.\n\nArguments:\n\n- scope: A [Scope](/versions/r1.15/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- input: 4-D with shape `[batch, in_height, in_width, in_channels]`.\n- size: A 1-D int32 [Tensor](/versions/r1.15/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor) of 2 elements: `new_height, new_width`. The new size for the images.\n- paddings: A two-column matrix specifying the padding sizes. The number of rows must be the same as the rank of `input`.\n- filter: 4-D with shape `[filter_height, filter_width, in_channels, out_channels]`.\n- strides: 1-D of length 4. The stride of the sliding window for each dimension of `input`. Must be in the same order as the dimension specified with format.\n- padding: The type of padding algorithm to use.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r1.15/api_docs/cc/struct/tensorflow/ops/fused-resize-and-pad-conv2-d/attrs#structtensorflow_1_1ops_1_1_fused_resize_and_pad_conv2_d_1_1_attrs)):\n\n- resize_align_corners: If true, the centers of the 4 corner pixels of the input and output tensors are aligned, preserving the values at the corner pixels. Defaults to false.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r1.15/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): The output tensor.\n\n\u003cbr /\u003e\n\n| ###
