Installation

Follow https://github.com/fundamentalvision/BEVFormer/blob/master/docs/install.md to prepare the environment.

Preparing Dataset

  1. Download the nuScenes dataset and put in into data/nuscenes

  2. Download our openocc_v2.1.zip and infos.zip from HERE and unzip them in data/nuscenes.

  3. Organize your folder structure as below：

data/nuscenes
├── maps
├── nuscenes_infos_train_occ.pkl
├── nuscenes_infos_val_occ.pkl
├── openocc_v2
├── samples
├── sweeps
├── v1.0-test
└── v1.0-trainval

Training

./tools/dist_train.sh projects/configs/bevformer/bevformer_base_occ.py 8

Testing

export CUDA_VISIBLE_DEVICES=0
./tools/dist_test.sh projects/configs/bevformer/bevformer_base_occ.py work_dirs/bevformer_base_occ/epoch_24.pth 1

Test Submission

  1. Fill your information in projects/mmdet3d_plugin/datasets/nuscenes_occ.py (Line 231).

  2. Test the baseline model on the test split with 8 GPUs, and generate the submission to the official evaluation server.

./tools/dist_test.sh projects/configs/bevformer/bevformer_base_occ_test.py work_dirs/bevformer_base_occ/epoch_24.pth 8 --format-only --eval-options 'submission_prefix=./occ_submission'
  1. The submission file is located in occ_submission/submission.gz. Good luck!
