WebAug 17, 2024 · Synchronized BatchNorm (AKA Cross-Replica BatchNorm). We tried out two variants of this, but for some unknown reason it crippled training each time. We have not tried the apex SyncBN as my school's servers are on ancient NVIDIA drivers that don't support it--apex would probably be a good place to start.
