Mengekstrak gradien renggang rata-rata di SparseConditionalAccumulator.
Operasi akan memblokir hingga gradien yang cukup (yaitu, lebih dari jumlah_yang diperlukan) telah terakumulasi. Jika akumulator telah mengumpulkan lebih dari num_required gradien, akumulator akan mengembalikan rata-rata akumulasi gradien. Juga secara otomatis menambah global_step yang tercatat di akumulator sebesar 1, dan menyetel ulang agregat ke 0.
