🏃‍♂️ Getting Started

Due to the copyright issue, we are unable to release all the processed datasets, we provide a sampled dataset and all the dataset labels for inference. Please download the sampled datasets and pretrained checkpoints from release. Then modify the path to data and checkpoints in the scripts. Run training:

bash dist_train.sh

Run inference:

bash inference.sh
