question of voxelnet_second

[RickOnEarth]

Hi @Jaekyumkim ,thank you for your outstanding work. I am trying to run the second stage of the code. In the class VoxelNet (in voxelnet_second.py), self.rpn is initialized as rpn_class_dic["RPN_SECOND_FUSION"], and self.second_rpn is initialized as rpn_class_dict["RPN_FUSION"]. Is it reversed?
Also the part second_preds_dict = self.second_rpn(bev_crops_output, concat_crops_output) does't match the code in rpn.py. The number of input parameters is not even enough. Is there some code missing in rpn.py?
