<p style="text-align: center;">[ICCV 23] DLT: Conditioned layout generation with Joint Discrete-Continuous Diffusion Layout Transformer</p>

This repository is an official implementation of DLT paper. Please, refer to the paper for more details and project page for general overview.<div style="display: flex; flex-direction: column; align-items: center;">

Unconditional	Category	Category + Size

Dev environment

• Operating System: Ubuntu 18.04
• CUDA Version: 11.6
• Python Version: 3.9

Requirements

All relevant requirements are listed in environment.yml. We recommend using conda to create the appropriate environment and install the dependencies:

conda env create -f environment.yml
conda activate dlt

Datasets

Please download the public datasets at the following webpages. Put it in your folder and update ./dlt/configs/remote/dataset_config.yaml accordingly.

1. RICO
2. PubLayNet
3. Magazine

Training

You can train the model using any config script in configs folder. For example, if you want to train the provided DLT model on publaynet dataset, the command is as follows:

cd dlt
python main.py --config configs/remote/dlt_publaynet_config.yaml --workdir <WORKDIR>

Please, see that code is accelerator agnostic. if you don't want to log results to wandb, just set --workdir test in args.

Evaluation

To generate samples for evaluation on the test set, follow these steps:

• train the model using the above command
• Run the following command:

# put weights in config.logs folder
DATASET = "publaynet" # or "rico" or "magazine"
python generate_samples.py --config configs/remote/dlt_{$DATASET}_config.yaml \\
                           --workdir <WORKDIR> --epoch <EPOCH> --cond_type <COND_TYPE> \\
                           --save True
# get all the metrics 
# update path to pickle file in dlt/evaluation/metric_comp.py
./download_fid_model.sh
python metric_comp.py

where <COND_TYPE> can be: (all, whole_box, loc) - (unconditional, category, category+size) respectively, <EPOCH> is the epoch number of the model you want to evaluate, and <WORKDIR> is the path to the folder where the model weights are saved (e.g. rico_final). The generated samples will be saved in logs/<WORKDIR>/samples folder if save True.

An output from it is pickle file with generated samples. You can use it to calculate metrics.

The folder with weights after training has this structure:

logs
├── magazine_final
│   ├── checkpoints
│   └── samples
├── publaynet_final
│   ├── checkpoints
│   └── samples
└── rico_final
    ├── checkpoints
    └── samples
