1.2 Build from source

git clone https://github.com/poodarchu/EFG.git
cd EFG
pip install -v -e .
# set logging path to save model checkpoints, training logs, etc.
echo "export EFG_CACHE_DIR=/path/to/your/logs/dir" >> ~/.bashrc

2. Data

2.1 Data Preparation - Waymo

# download waymo dataset v1.2.0 (or v1.3.2, etc)
gsutil -m cp -r \
  "gs://waymo_open_dataset_v_1_2_0_individual_files/testing" \
  "gs://waymo_open_dataset_v_1_2_0_individual_files/training" \
  "gs://waymo_open_dataset_v_1_2_0_individual_files/validation" \
  .

# extract frames from tfrecord to pkl
CUDA_VISIBLE_DEVICES=-1 python cli/data_preparation/waymo/waymo_converter.py --record_path "/path/to/waymo/training/*.tfrecord" --root_path "/path/to/waymo/train/"
CUDA_VISIBLE_DEVICES=-1 python cli/data_preparation/waymo/waymo_converter.py --record_path "/path/to/waymo/validation/*.tfrecord" --root_path "/path/to/waymo/val/"

# create softlink to datasets
cd /path/to/EFG/datasets; ln -s /path/to/waymo/dataset/root waymo; cd ..
# create data summary and gt database from extracted frames
python cli/data_preparation/waymo/create_data.py --root-path datasets/waymo --split train --nsweeps 1
python cli/data_preparation/waymo/create_data.py --root-path datasets/waymo --split val --nsweeps 1

2.2 Data Preparation - nuScenes

# nuScenes

dataset/nuscenes
├── can_bus
├── lidarseg
├── maps
├── occupancy
│   ├── annotations.json
│   └── gts
├── panoptic
├── samples
├── sweeps
├── v1.0-mini
├── v1.0-test
└── v1.0-trainval

# create softlink to datasets
cd /path/to/EFG/datasets; ln -s /path/to/nuscenes/dataset/root nuscenes; cd ..
# suppose that here we use nuScenes/samples images, put gts and annotations.json under nuScenes/occupancy
python cli/data_preparation/nuscenes/create_data.py --root-path datasets/nuscenes --version v1.0-trainval --nsweeps 11 --occ --seg

3. Get Started

3.1 Training & Evaluation

# cd playground/path/to/experiment/directory

efg_run --num-gpus x  # default 1
efg_run --num-gpus x task [train | val | test]
efg_run --num-gpus x --resume
efg_run --num-gpus x dataloader.num_workers 0  # dynamically change options in config.yaml

Models will be evaluated automatically at the end of training. Or,

efg_run --num-gpus x task val

4. Model ZOO

All models are trained and evaluated on 8 x NVIDIA A100 GPUs.
