fluxo tensor:: ops:: Juntar #include <array_ops.h>
Reúna fatias de params
de acordo com indices
.
Resumo indices
devem ser um tensor inteiro de qualquer dimensão (geralmente 0-D ou 1-D). Produz um tensor de saída com shape indices.shape + params.shape[1:]
onde:
# Scalar indices
output[:, ..., :] = params[indices, :, ... :]
# Vector indices
output [ i, :, ..., : ] = params [ indices[i ] , : , ... :]
# Higher rank indices
output[i, ..., j, :, ... :] = params[indices[i, ..., j], :, ..., :] Se indices
for uma permutação e len(indices) == params.shape[0]
então esta operação permutará params
de acordo.
validate_indices
: DEPRECADO. Se esta operação for atribuída à CPU, os valores nos indices
serão sempre validados para estarem dentro do intervalo. Se atribuídos à GPU, os índices fora do limite resultam em um comportamento seguro, mas não especificado, que pode incluir o surgimento de um erro.

Produces an output tensor with shape `indices.shape + params.shape[1:]` where:\n\n\n```text\n # Scalar indices\n output[:, ..., :] = params[indices, :, ... :]\n```\n\n\u003cbr /\u003e\n\n\n```transact-sql\n # Vector indices\n output[i, :, ..., :] = params[indices[i], :, ... :]\n```\n\n\u003cbr /\u003e\n\n\n```text\n # Higher rank indices\n output[i, ..., j, :, ... :] = params[indices[i, ..., j], :, ..., :]\n```\n\n\u003cbr /\u003e\n\nIf `indices` is a permutation and `len(indices) == params.shape[0]` then this operation will permute `params` accordingly.\n\n`validate_indices`: DEPRECATED. If this operation is assigned to CPU, values in `indices` are always validated to be within range. If assigned to GPU, out-of-bound indices result in safe but unspecified behavior, which may include raising an error.\n\n\n\u003cbr /\u003e\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n\n\u003cbr /\u003e\n\nReturns:\n\n- [Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output): The output tensor.\n\n\u003cbr /\u003e\n\n| ### Constructors and Destructors ||\n|---|---|\n| [Gather](#classtensorflow_1_1ops_1_1_gather_1a839275b14b2a970a2bdaafee039469dd)`(const ::`[tensorflow::Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` params, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` indices)` ||\n| [Gather](#classtensorflow_1_1ops_1_1_gather_1aafacd8f95dd561da28cb61d32a6a315f)`(const ::`[tensorflow::Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope)` & scope, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` params, ::`[tensorflow::Input](/versions/r2.1/api_docs/cc/class/tensorflow/input#classtensorflow_1_1_input)` indices, const `[Gather::Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/gather/attrs#structtensorflow_1_1ops_1_1_gather_1_1_attrs)` & attrs)` ||\n\n| ### Public attributes ||\n|------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------|\n| [operation](#classtensorflow_1_1ops_1_1_gather_1a324a25a3a94bb8ec9ea1f0c18e864f7d) | [Operation](/versions/r2.1/api_docs/cc/class/tensorflow/operation#classtensorflow_1_1_operation) |\n| [output](#classtensorflow_1_1ops_1_1_gather_1a9d78b5b304387efee0e53b5afaa384ef) | `::`[tensorflow::Output](/versions/r2.1/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output) |\n\n| ### Public functions ||\n|------------------------------------------------------------------------------------------------------------------|------------------------|\n| [node](#classtensorflow_1_1ops_1_1_gather_1a6861dab37fe274f230029422bd94b724)`() const ` | `::tensorflow::Node *` |\n| [operator::tensorflow::Input](#classtensorflow_1_1ops_1_1_gather_1a8ea808391c4824b35409a4427fcfd5eb)`() const ` | ` ` ` ` |\n| [operator::tensorflow::Output](#classtensorflow_1_1ops_1_1_gather_1a3dfd72e34f22afeaad6918d75a6cfdcd)`() const ` | ` ` ` ` |\n\n| ### Public static functions ||\n|----------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------|\n| [ValidateIndices](#classtensorflow_1_1ops_1_1_gather_1acb10767dcd5da7c1d454b97feafe2f3b)`(bool x)` | [Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/gather/attrs#structtensorflow_1_1ops_1_1_gather_1_1_attrs) |\n\n| ### Structs ||\n|-------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------|\n| [tensorflow::ops::Gather::Attrs](/versions/r2.1/api_docs/cc/struct/tensorflow/ops/gather/attrs) | Optional attribute setters for [Gather](/versions/r2.1/api_docs/cc/class/tensorflow/ops/gather#classtensorflow_1_1ops_1_1_gather). |\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### Gather\n\n```gdscript\n Gather(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input params,\n ::tensorflow::Input indices\n)\n``` \n\n### Gather\n\n```gdscript\n Gather(\n const ::tensorflow::Scope & scope,\n ::tensorflow::Input params,\n ::tensorflow::Input indices,\n const Gather::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### ValidateIndices\n\n```text\nAttrs ValidateIndices(\n bool x\n)\n```"]]
