Extrait le gradient clairsemé moyen dans un SparseConditionalAccumulator.
L'opération se bloquera jusqu'à ce que suffisamment de gradients (c'est-à-dire plus que num_required) aient été accumulés. Si l'accumulateur a déjà agrégé plus de num_required gradients, il renverra sa moyenne des gradients accumulés. Incrémente également automatiquement le global_step enregistré dans l'accumulateur de 1 et réinitialise l'agrégat à 0.
