There is a bug in heter_model_late.py.

[xhjy2020]

Hello! In opencood/models/heter_model_late.py , line 14, from opencood.models.sub_modules.roi_align_fe import RoIAlignFeatureExtractor, there is no 'roi_align_fe' files.

I want to train no-fusion models. I notice that there are some xxx_pretrain.yaml, are these files for train late-fusion models? No-fusion is only supported during inference?

Hi! RoIAlignFeatureExtractor is no longer needed. I remove it in the latest commit.

The late fusion and no fusion share the same yaml. They are both trained on a single agent, without collaboration. In the inference stage, use

• --fusion_method no for no fusion (ego agent, collaborative GT label)
• --fusion_method late for late fusion (collaborative agents, collaborative GT label)
• --fusion_method single for single agent evaluation (ego agent, ego GT label)

I got it, thanks for your patient elaboration~
