Bir SparseConditionalAccumulator'daki ortalama seyrek degradeyi ayıklar.
Op, yeterli (yani gerekli sayıdan fazla) degradeler birikene kadar bloke edecektir. 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.
