Setup

To install requirements, run:

git clone https://github.com/mlvlab/Flipped-VQA.git
cd Flipped-VQA
mkdir pretrained
conda create -n flipped-vqa python=3.8
conda activate flipped-vqa
sh setup.sh

Dataset & LLaMA Preparation

• You can download our preprocessed datasets (NExT-QA, STAR, DramaQA, VLEP and TVQA) in huggingface (We also provide the fine-tuned model on each dataset).

git lfs install
git clone https://huggingface.co/datasets/ikodoh/Flipped-VQA-Data
mv ./Flipped-VQA-Data/data ./
mv ./Flipped-VQA-Data/checkpoint ./
unzip ./data/tvqa/tvqa_subtitles.zip -d ./data/tvqa
rm -rf Flipped-VQA-Data ./data/tvqa/tvqa_subtitles.zip

• You can download original LLaMA at here, and put the checkpoint in ./pretrained.

The fine-tuned checkpoints on each dataset are here.

Evaluation

From the training command, simply replace train.py with eval.py and add --resume ./your/checkpoint.pth.
