Installation and Dataset Download

For installation, please follow the installation process as mentioned here. For dataset download and preprocessing, follow the instructions mentioned for VQA-X.

Training

1. We use pretrained VQA model which can be downloaded from here
2. Modify the config.py as per the requirement. Now, we can train the model

python train.py

Generating Explanations

The pretrained model can be downloaded from here. Place the pretrained model in the path model Provide the directory as input and run the command: cd generate_vqa_exp

python generate_explanation.py --ques_file ../VQA-X/Questions/v2_OpenEnded_mscoco_val2014_questions.json --ann_file ../VQA-X/Annotations/v2_mscoco_val2014_annotations.json --exp_file ../VQA-X/Annotations/val_exp_anno.json --gpu 0 --out_dir ../VQA-X/results --folder ../model/ --model_path $PATH_TO_CAFFEMODEL --use_gt --save_att_map
