Note
Each dataset may have each different way of providing mask annotation and metadata, so you should match the Dataset class for each dataset with its desired configuration.

Installation

This repo is developed based on Lightning-Hydra-Template 1.5.3 with Python 3.8.12 and PyTorch 1.11.0.

Pip

# clone project
git clone https://github.com/janghyuk-choi/slot-attention-lightning.git
cd slot-attention-lightning

# [OPTIONAL] create conda environment
conda create -n slota python=3.8
conda activate slota

# install pytorch according to instructions
# https://pytorch.org/get-started/

# install requirements
pip install -r requirements.txt

Conda

# clone project
git clone https://github.com/janghyuk-choi/slot-attention-lightning.git
cd slot-attention-lightning

# create conda environment and install dependencies
conda env create -f environment.yaml

# activate conda environment
conda activate slota

How to run

Train model with chosen experiment configuration from configs/experiment/

Training

# training Slot Attention over CLEVR6 dataset
python src/train.py \
experiment=slota/clv6.yaml

# training Genesis V2 over CLEVRTEX dataset
python src/train.py \
experiment=genesis2/clvt.yaml

You can create your own expreiment configs for the purpose.
But, for simple modification, you can override any parameter from command line.

# training Slot Attention over CLEVR6 dataset with custom config
python src/train.py \
experiment=slota/clv6.yaml \
data.data_dir=/workspace/dataset/clevr_with_masks/CLEVR6 \
trainer.check_val_every_n_epoch=10 \
model.net.num_slots=10 \
model.net.num_iter=5 \
model.name="slota_k10_t5" # model.name will be used for logging on wandb

Evaluation

You can evaluate a trained model with the corresponding checkpoint.
The evaluation is also conducted during training with the interval of trainer.check_val_every_n_epoch.

# evaluating Slot Attention over CLEVR6 dataset.
# similar to the training phase, you can also customize the config with command line
python src/eval.py \
experiment=slota/clv6.yaml \
ckpt_path=logs/train/runs/clv6_slota/{timestamp}/checkpoints/last.ckpt
