# 2017 VQA Challenge Winner (CVPR'17 Workshop)
pytorch implementation of [Tips and Tricks for Visual Question Answering: Learnings from the 2017 Challenge by Teney et al](https://arxiv.org/pdf/1708.02711.pdf).
## Prerequisites
- python 3.6+
- numpy
- [pytorch](http://pytorch.org/) 0.4
- [tqdm](https://pypi.python.org/pypi/tqdm)
- [nltk](http://www.nltk.org/install.html)
- [pandas](https://pandas.pydata.org/)
## Data
- [VQA 2.0](http://visualqa.org/download.html)
- [COCO 36 features pretrained resnet model](https://github.com/peteanderson80/bottom-up-attention#pretrained-features)
- [GloVe pretrained Wikipedia+Gigaword word embedding](https://nlp.stanford.edu/projects/glove/)
## Preparation
- To download and extract vqav2, glove, and pretrained visual features:
```bash
bash scripts/download_extract.sh
```
- To prepare data for training:
```bash
python scripts/preproc.py
```
- The structure of `data/` directory should look like this:
```
- data/
- zips/
- v2_XXX...zip
- ...
- glove...zip
- trainval_36.zip
- glove/
- glove...txt
- ...
- v2_XXX.json
- ...
- trainval_resnet...tsv
(The above are files created after executing scripts/download_extract.sh)
- tokenizers/
- ...
- dict_ans.pkl
- dict_q.pkl
- glove_pretrained_300.npy
- train_qa.pkl
- val_qa.pkl
- train_vfeats.pkl
- val_vfeats.pkl
(The above are files created after executing scripts/preproc.py)
```
## Train
Use default parameters:
```bash
bash scripts/train.sh
```
## Notes
- Huge re-factor (especially data preprocessing), tested based on pytorch 0.4.1 and python 3.6
- Training for 20 epochs reach around 50% training accuracy. (model seems buggy in my implementation)
- After all the preprocessing, `data/` directory may be up to 38G+
- Some of `preproc.py` and `utils.py` are based on [this repo](https://github.com/hengyuan-hu/bottom-up-attention-vqa)
