News

• (2022/6/27) DeepInteraction-e ranks first on nuScenes among all solutions.
• (2022/6/26) DeepInteraction-large ranks first on nuScenes among all non-ensemble solutions.
• (2022/5/18) DeepInteraction-base ranks first on nuScenes among all solutions that do not use test-time augmentation and model ensemble.

Get Started

Environment

This implementation is build upon mmdetection3d, please follow the steps in install.md to prepare the environment.

Data

Please follow the official instructions of mmdetection3d to process the nuScenes dataset.(https://mmdetection3d.readthedocs.io/en/latest/datasets/nuscenes_det.html)

Pretrained
