Introduction

This is the official PyTorch implementation for paper: SlotFormer: Unsupervised Visual Dynamics Simulation with Object-Centric Models, which is accepted by ICLR 2023. The code contains:

• Training base object-centric slot models
• Video prediction task on OBJ3D and CLEVRER
• VQA task on CLEVRER
• VQA task on Physion
• Planning task on PHYRE

Update

• 2023.9.20: BC-breaking change! We fix an error in the mIoU calculation code. This won't change the order of benchmarked methods, but will change their absolute values. See this PR for more details. Please re-run the evaluation code on your trained models to get the correct results. The updated mIoU of SlotFormer on CLEVRER is 49.42 (using the provided pre-trained weight)
• 2023.1.20: The paper is accepted by ICLR 2023!
• 2022.10.26: Support Physion VQA task and PHYRE planning task
• 2022.10.16: Initial code release!
  • Support base object-centric model training
  • Support SlotFormer training
  • Support evaluation on the video prediction task
  • Support evaluation on the CLEVRER VQA task

Installation

Please refer to install.md for step-by-step guidance on how to install the packages.

Experiments

This codebase is tailored to Slurm GPU clusters with preemption mechanism. For the configs, we mainly use RTX6000 with 24GB memory (though many experiments don't require so much memory). Please modify the code accordingly if you are using other hardware settings:

• Please go through scripts/train.py and change the fields marked by TODO:
• Please read the config file for the model you want to train. We use DDP with multiple GPUs to accelerate training. You can use less GPUs to achieve a better memory-speed trade-off

Dataset Preparation

Please refer to data.md for steps to download and pre-process each dataset.
