Computes the full schedule array in ``on_train_start`` using :func:`rfdetr.util.drop_scheduler.drop_scheduler`, then indexes into it on every training batch to update the model's stochastic-depth and dropout rates. Args: drop_path: Peak drop-path rate. ``0.0`` disables the schedule. dropout: Peak dropout rate. ``0.0`` disables the schedule. cutoff_epoch: Epoch boundary for *early* / *late* modes. mode: Schedule mode forwarded to ``drop_scheduler``. schedule: Schedule shape forwarded to ``drop_scheduler``. vit_encoder_num_layers: Passed to ``model.update_drop_path`` so the model can distribute rates across ViT encoder layers. ct|||_||_||_||_||_||_d|_d|_ y)N) super__init__ _drop_path_dropout _cutoff_epoch_mode _schedule_vit_encoder_num_layers _dp_schedule _do_schedule)self drop_pathdropout cutoff_epochmodeschedulevit_encoder_num_layers __class__s r/var/www/ramen.bs-engineer-server.com/venv/lib/python3.12/site-packages/rfdetr/training/callbacks/drop_schedule.pyrzDropPathCallback.__init__"sL # ) !'=$2626c|jj}t|j}t d||z}|j dkDr=t |j |||j|j|j|_ |jdkDr>t |j|||j|j|j|_ yy)zBuild per-step rate arrays from trainer metadata.
