# ===========================================================
# 5. XFormers patches — DISABLED
# Sub 168 (base image) achieved output_tps=11.9 WITHOUT any xformers patches.
# Sub 520 applied these patches → output_tps=2.6 (4.6x slower!)
# The patches replace ixformer flash attention with pure PyTorch O(L²) matmul.
# Base image ixformer attention works correctly — proven by Sub 168.
# 5. XFormers patches — head_dim=256 bypass for BI-V100
# Comp 168 also had xformers patches (base uses xformers for attention)
