Dataset

Please follow this repo to generate your own dataset.

Code

Codes are tested on Ubuntu 18 and cuda 9.2.

Installation

1. Create a conda environment

conda create -n TIE python=3.6
conda activate TIE

2. Clone and install this repo

git clone https://github.com/ftbabi/TIE_ECCV2022.git

cd TIE_ECCV2022
pip install -v -e .

3. Install PyTorch and torchvision following the official instructions, e.g.,

conda install pytorch==1.7.0 torchvision==0.8.0 torchaudio==0.7.0 cudatoolkit=9.2 -c pytorch

4. Install mmcv-full

pip install mmcv-full==1.3.1 -f https://download.openmmlab.com/mmcv/dist/cu92/torch1.7.0/index.html

5. Install dependent packages

pip install h5py==2.8.0 scipy==1.5.0 tqdm scikit-learn==0.23.1

conda install pybind11==2.7.0  # This is for rendering

Training

Please update the variable dataf in corresponding dataset's config configs/_base_/datasets/xxx.py to your data path.

1. Train on slurm system

./tools/slurm_train.sh {PARTITION} {JOB_NAME} {CONFIG} {WORK_DIR} # please refer to `tools/slurm_train.sh for more details

2. Train on multiple GPUs

python tools/train.py {CONFIG} {WORK_DIR}

Testing

1. Predict rollout on slurm system

./tools/slurm_predict.sh {PARTITION} {JOB_NAME} {CONFIG} {WORK_DIR} --checkpoint {CHECKPOINT}

2. Predict rollout on single GPU

python tools/predict_rollout.py {CONFIG} {WORK_DIR} --checkpoint {CHECKPOINT}

Rendering

Please make sure you have followed this repo to generate your own dataset.

python tools/render_rollout.py {CONFIG} {SRC_DIR} --save_dir {SAVE_DIR}

Please refer to tools/render_rollout.py for more details.
