LayoutTransformer

Pytorch implementation for LT-Net. The goal is to generate scene layout with conceptual and spatial diversity.

Overview

UPdates

• The training code on the VG-msdn dataset might have some minor errors. We will fix them ASAP.

Data

• Please setup conda envirnment first by following command.
  • Create conda env

conda create -n ltnet python=3.6
conda activate ltnet

- Install pip packages

pip install -r requirements.txt 

Data

• COCO dataset
  • Download the annotations from COCO.
  • i.e., 2017 Train/Val annotations [241MB] and 2017 Stuff Train/Val annotations [1.1GB]
  • Extract the annotations to data/coco/
• VG-MSDN dataset
  • Download the VG-MSDN dataset from VG-MSDN. (This dataset origins from FactorizableNet)
  • Extract the annotations (i.e., all json files) to data/vg_msdn/

Training

All code was developed and tested on Ubuntu 20.04 with Python 3.7 (Anaconda) and PyTorch 1.7.1.

Pre-train the Obj/Rel Rredictor

• Pre-train Predictor module for COCO dataset:

python3 train.py --cfg_path ./configs/coco/coco_pretrain.yaml

• Pre-train Predictor model for VG-MSDN dataset:

python3 train.py --cfg_path ./configs/vg_msdn/vg_msdn_pretrain.yaml

Full module

• Train full model for COCO dataset:

python3 train.py --cfg_path ./configs/coco/coco_seq2seq_v9_ablation_4.yaml

• Train full model for VG-MSDN dataset:

python3 train.py --cfg_path ./configs/vg_msdn/vg_msdn_seq2seq_v24.yaml

*.yml files include configuration for training and testing.

Please note that you might need to modify the config file to fit the corresponding path on your device if the data is placed in other places.

Evaluation

LayoutTransformer full model

• Evaluate full model for COCO dataset: (Please download or train your LayoutTransformer for COCO first.)

python3 train.py --cfg_path [PATH_TO_CONFIG_FILE] --checkpoint [PATH_TO_THE_WEIGHT_FOR_LAYOUTTRASFORMER] --eval_only

For example,

python3 train.py --cfg_path configs/coco/coco_seq2seq_v9_ablation_4.yaml --checkpoint ./saved/coco_F_seq2seq_v9_ablation_4/checkpoint_50_0.44139538748348955.pth --eval_only

• Evaluate full model for VG-MSDN dataset: (Please download or train your LayoutTransformer for vg-msdn first.)

python3 train.py --cfg_path [PATH_TO_CONFIG_FILE] --checkpoint [PATH_TO_THE_WEIGHT_FOR_LAYOUTTRASFORMER] --eval_only

For example,

python3 train.py --cfg_path configs/vg_msdn/vg_msdn_seq2seq_v24.yaml --checkpoint ./saved/vg_msdn_F_seq2seq_v24/checkpoint_50_0.16316922369277578.pth --eval_only
