May I ask how to conduct the delay experiment? I performed inference on the DAIR-V2X dataset using the following command:

python /mnt/yhl_delay/CodeFilling/opencood/tools/inference_comm_bp_plus.py
--delay_time 5
--model_dir /mnt/yhl_delay/CodeFilling/opencood/logs_HEAL/dair_point_pillar_where2comm_2025_10_07_16_31_10
--fusion_method intermediate
--modal 0

However, the results did not change, and the delay seems to have no effect.
