Integrating Visuospatial, Linguistic and Commonsense Structure into Story Visualization

PyTorch code for the EMNLP 2021 paper "Integrating Visuospatial, Linguistic and Commonsense Structure into Story Visualization". See the arxiv paper here.

Requirements:

This code has been tested on torch==1.11.0.dev20211014 (nightly) and torchvision==0.12.0.dev20211014 (nightly)

Prepare Repository:

Download the PororoSV dataset and associated files from here and save it as ./data. Download GloVe embeddings (glove.840B.300D) from here. The default location of the embeddings is ./data/ (see ./dcsgan/miscc/config.py).

Extract Constituency Parses:

To install the Berkeley Neural Parser with SpaCy:

pip install benepar

To extract parses for PororoSV:

python parse.py --dataset pororo --data_dir <path-to-data-directory>

Extract Dense Captions:

We use the Dense Captioning Model implementation available here. Download the pretrained model as outlined in their repository. To extract dense captions for PororoSV:
python describe_pororosv.py --config_json <path-to-config> --lut_path <path-to-VG-regions-dict-lite.pkl> --model_checkpoint <path-to-model-checkpoint> --img_path <path-to-data-directory> --box_per_img 10 --batch_size 1

Training VLC-StoryGAN:

To train VLC-StoryGAN for PororoSV:
python train_gan.py --cfg ./cfg/pororo_s1_vlc.yml --data_dir <path-to-data-directory> --dataset pororo\

Unless specified, the default output root directory for all model checkpoints is ./out/

Evaluation Models:

Please see here for evaluation models for character classification-based scores, BLEU2/3 and R-Precision.

To evaluate Frechet Inception Distance (FID):
python eval_vfid --img_ref_dir <path-to-image-directory-original images> --img_gen_dir <path-to-image-directory-generated-images> --mode <mode>

More details coming soon.
