fluxo tensor:: ops:: BiasAddGrad
#include <nn_ops.h> A operação reversa para "BiasAdd" no tensor "bias".
Resumo
Ele acumula todos os valores de out_backprop na dimensão do recurso. Para o formato de dados NHWC, a dimensão do recurso é a última. Para o formato de dados NCHW, a dimensão do recurso é a penúltima.
Argumentos:
Atributos opcionais (veja Attrs ):
- data_format: Especifique o formato dos dados de entrada e saída. Com o formato padrão "NHWC", o tensor de polarização será adicionado à última dimensão do tensor de valor. Alternativamente, o formato pode ser "NCHW", a ordem de armazenamento de dados de: [lote, in_channels, in_height, in_width]. O tensor será adicionado a "in_channels", a penúltima dimensão.

Output : 1-D com tamanho da dimensão do recurso out_backprop .

For NHWC data format, the feature dimension is the last. For NCHW data format, the feature dimension is the third-to-last.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- out_backprop: [Any](/versions/r2.3/api_docs/cc/class/tensorflow/ops/any#classtensorflow_1_1ops_1_1_any) number of dimensions.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/bias-add-grad/attrs#structtensorflow_1_1ops_1_1_bias_add_grad_1_1_attrs)):\n\n- data_format: Specify the data format of the input and output data. With the default format \"NHWC\", the bias tensor will be added to the last dimension of the value tensor. Alternatively, the format could be \"NCHW\", the data storage order of: \\[batch, in_channels, in_height, in_width\\]. The tensor will be added to \"in_channels\", the third-to-the-last dimension.\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): 1-D with size the feature dimension of `out_backprop`.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n| [BiasAddGrad](#classtensorflow_1_1ops_1_1_bias_add_grad_1a0b471227bda69729c6aef3eedee7ce76)`(const ::`[tensorflow::Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.3/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` out_backprop)` ||\n| [BiasAddGrad](#classtensorflow_1_1ops_1_1_bias_add_grad_1a7ed7a556f0defe36d84e76b4e1d82520)`(const ::`[tensorflow::Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.3/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` out_backprop, const `[BiasAddGrad::Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/bias-add-grad/attrs#structtensorflow_1_1ops_1_1_bias_add_grad_1_1_attrs)` & attrs)` ||\n\n| ### Public attributes ||\n|-------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|\n| [operation](#classtensorflow_1_1ops_1_1_bias_add_grad_1aac9a30fd0d04953d33bfab584e16129e) | [Operation](/versions/r2.3/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation) |\n| [output](#classtensorflow_1_1ops_1_1_bias_add_grad_1ad08acfbdc2d0884b697b7a5bbc697ae8) | `::`[tensorflow::Output](/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) |\n\n| ### Public functions ||\n|-------------------------------------------------------------------------------------------------------------------------|------------------------|\n| [node](#classtensorflow_1_1ops_1_1_bias_add_grad_1aeccff457f3c53d6baabeb9c55f6652f2)`() const ` | `::tensorflow::Node *` |\n| [operator::tensorflow::Input](#classtensorflow_1_1ops_1_1_bias_add_grad_1a5bad18eefc1b7c3abb7e355a2ac9f7e8)`() const ` | ` ` ` ` |\n| [operator::tensorflow::Output](#classtensorflow_1_1ops_1_1_bias_add_grad_1a2599155ff799c242f1114fe34acc6280)`() const ` | ` ` ` ` |\n\n| ### Public static functions ||\n|-------------------------------------------------------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------|\n| [DataFormat](#classtensorflow_1_1ops_1_1_bias_add_grad_1a2d3136a07563909023605499a1fd4600)`(StringPiece x)` | [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/bias-add-grad/attrs#structtensorflow_1_1ops_1_1_bias_add_grad_1_1_attrs) |\n\n| ### Structs ||\n|-------------------------------------------------------------------------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [tensorflow::ops::BiasAddGrad::Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/bias-add-grad/attrs) | Optional attribute setters for [BiasAddGrad](/versions/r2.3/api_docs/cc/class/tensorflow/ops/bias-add-grad#classtensorflow_1_1ops_1_1_bias_add_grad). |\n\nPublic attributes\n-----------------\n\n### operation\n\n```text\nOperation operation\n``` \n\n### output\n\n```text\n::tensorflow::Output output\n``` \n\nPublic functions\n----------------\n\n### BiasAddGrad\n\n```gdscript\n BiasAddGrad(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input out_backprop\n)\n``` \n\n### BiasAddGrad\n\n```gdscript\n BiasAddGrad(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input out_backprop,\n const BiasAddGrad::Attrs & attrs\n)\n``` \n\n### node\n\n```gdscript\n::tensorflow::Node * node() const \n``` \n\n### operator::tensorflow::Input\n\n```gdscript\n operator::tensorflow::Input() const \n``` \n\n### operator::tensorflow::Output\n\n```gdscript\n operator::tensorflow::Output() const \n``` \n\nPublic static functions\n-----------------------\n\n### DataFormat\n\n```text\nAttrs DataFormat(\n StringPiece x\n)\n```"]]
