tensor akışı:: işlem:: AkümülatörTakeGradient
#include <data_flow_ops.h>
Belirtilen ConditionalAccumulator'daki ortalama degradeyi çıkarır.
Özet
Yeterli (yani gerekli sayıdan fazla) degradeler birikene kadar op blokları. Akümülatör zaten gereken sayıdan fazla degradeyi toplamışsa, biriken degradelerin ortalamasını döndürür. Ayrıca akümülatördeki kayıtlı global_step değerini otomatik olarak 1 artırır ve toplamı 0'a sıfırlar.
Argümanlar:
- kapsam: Bir Kapsam nesnesi
- tanıtıcı: Bir akümülatörün tutacağı.
- num_required: Bir toplama döndürmeden önce gereken degrade sayısı.
- dtype: Birikmiş degradelerin veri türü. Akümülatör tipine uygun olması gerekir.
İade:
-
Output
: Birikmiş eğimlerin ortalaması.

Also automatically increments the recorded global_step in the accumulator by 1, and resets the aggregate to 0.\n\nArguments:\n\n- scope: A [Scope](/versions/r2.1/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object\n- handle: The handle to an accumulator.\n- num_required: Number of gradients required before we return an aggregate.\n- dtype: The data type of accumulated gradients.
