#include <data_flow_ops.h>
Un accumulateur conditionnel pour agréger des gradients clairsemés.
Résumé
L'accumulateur accepte les gradients marqués d'un local_step supérieur ou égal au global_step le plus récent connu de l'accumulateur. La moyenne peut être extraite de l'accumulateur, à condition que suffisamment de gradients aient été accumulés. L'extraction de la moyenne réinitialise automatiquement l'agrégat à 0 et incrémente le global_step enregistré par l'accumulateur.
Arguments :
- scope : un objet Scope
- dtype : Le type de la valeur accumulée.
- shape : La forme des valeurs.
Attributs facultatifs (voir Attrs
) :
- conteneur : S'il n'est pas vide, cet accumulateur est placé dans le conteneur donné. Sinon, un conteneur par défaut est utilisé.
- shared_name : s'il n'est pas vide, cet accumulateur sera partagé sous le nom donné sur plusieurs sessions.

Output
: la poignée de l'accumulateur.

The average can be extracted from the accumulator, provided sufficient gradients have been accumulated. Extracting the average automatically resets the aggregate to 0, and increments the global_step recorded by the accumulator.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- dtype: The type of the value being accumulated.\n- shape: The shape of the values.\n\n\u003cbr /\u003e\n\nOptional attributes (see [Attrs](/versions/r2.3/api_docs/cc/struct/tensorflow/ops/sparse-conditional-accumulator/attrs#structtensorflow_1_1ops_1_1_sparse_conditional_accumulator_1_1_attrs)):\n\n- container: If non-empty, this accumulator is placed in the given container. Otherwise, a default container is used.\n- shared_name: If non-empty, this accumulator will be shared under the given name across multiple sessions.\n\n\u003cbr /\u003e\n\nReturns:\n\n-
