tensoreflusso:: ops:: SparseReduceSumSparse
#include <sparse_ops.h> Calcola la somma degli elementi attraverso le dimensioni di uno SparseTensor.
Riepilogo
Questo Op accetta uno SparseTensor ed è la controparte sparsa di tf.reduce_sum() . A differenza di SparseReduceSum , questo Op restituisce uno SparseTensor.
Riduce sp_input lungo le dimensioni indicate in reduction_axes . A meno che keep_dims non sia vero, il rango del tensore viene ridotto di 1 per ogni voce in reduction_axes . Se keep_dims è true, le dimensioni ridotte vengono mantenute con lunghezza 1.
Se reduction_axes non ha voci, tutte le dimensioni vengono ridotte e viene restituito un tensore con un singolo elemento. Inoltre, gli assi possono essere negativi, che vengono interpretati secondo le regole di indicizzazione in Python.
Argomenti:
- scope: un oggetto Scope
- input_indices: 2-D. Matrice
N x R con gli indici dei valori non vuoti in uno SparseTensor, possibilmente non in ordinamento canonico. - valori_input: 1-D.
N valori non vuoti corrispondenti a input_indices . - forma_input: 1-D. Forma dello SparseTensor in ingresso.
- assi_riduzione: 1-D. Lunghezza- Vettore
K contenente gli assi di riduzione.
Attributi facoltativi (vedi Attrs ):
- keep_dims: se vero, mantiene le dimensioni ridotte con lunghezza 1.

In contrast to [SparseReduceSum](/versions/r2.0/api_docs/cc/class/tensorflow/ops/sparse-reduce-sum#classtensorflow_1_1ops_1_1_sparse_reduce_sum), this Op returns a SparseTensor.\n\nReduces `sp_input` along the dimensions given in `reduction_axes`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `reduction_axes`. If `keep_dims` is true, the reduced dimensions are retained with length 1.\n\nIf `reduction_axes` has no entries, all dimensions are reduced, and a tensor with a single element is returned. Additionally, the axes can be negative, which are interpreted according to the indexing rules in Python.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.0/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- input_indices: 2-D. `N x R` matrix with the indices of non-empty values in a SparseTensor, possibly not in canonical ordering.\n- input_values: 1-D. `N` non-empty values corresponding to `input_indices`.\n- input_shape: 1-D. Shape of the input SparseTensor.\n- reduction_axes: 1-D. Length-`K` vector containing the reduction axes.\n\n\u003cbr /\u003e\n\nOptional attributes (see
