early_fusion复现不出来

[xuxian-0205]

根据early fusion的read me文件，我尝试复现，但复现结果并不如configs/vic3d/early-fusion-pointcloud/pointpillars展示的AP值那么高。
无延迟情况下，你的AP50高达68.91，而我复现的结果如下：

car 3d IoU threshold 0.30, Average Precision = 57.25
car 3d IoU threshold 0.50, Average Precision = 49.59
car 3d IoU threshold 0.70, Average Precision = 23.37
car bev IoU threshold 0.30, Average Precision = 58.33
car bev IoU threshold 0.50, Average Precision = 55.89
car bev IoU threshold 0.70, Average Precision = 48.00

AP值仅有55.89，使用的是你提供的权重，请问这是什么情况？
