Overview

D-VQA

We provide the PyTorch implementation for Debiased Visual Question Answering from Feature and Sample Perspectives (NeurIPS 2021).

D-VQA

Dependencies

  • Python 3.6
  • PyTorch 1.1.0
  • dependencies in requirements.txt
  • We train and evaluate all of the models based on one TITAN Xp GPU

Getting Started

Installation

  1. Clone this repository:

     git clone https://github.com/Zhiquan-Wen/D-VQA.git
 cd D-VQA

  2. Install PyTorch and other dependencies:

     pip install -r requirements.txt

Download and preprocess the data

cd data 
bash download.sh
python preprocess_features.py --input_tsv_folder xxx.tsv --output_h5 xxx.h5
python feature_preprocess.py --input_h5 xxx.h5 --output_path trainval 
python create_dictionary.py --dataroot vqacp2/
python preprocess_text.py --dataroot vqacp2/ --version v2
cd ..

Training

  • Train our model
CUDA_VISIBLE_DEVICES=0 python main.py --dataroot data/vqacp2/ --img_root data/coco/trainval_features --output saved_models_cp2/ --self_loss_weight 3 --self_loss_q 0.7
  • Train the model with 80% of the original training set
CUDA_VISIBLE_DEVICES=0 python main.py --dataroot data/vqacp2/ --img_root data/coco/trainval_features --output saved_models_cp2/ --self_loss_weight 3 --self_loss_q 0.7 --ratio 0.8

Evaluation

  • A json file of results from the test set can be produced with:
CUDA_VISIBLE_DEVICES=0 python test.py --dataroot data/vqacp2/ --img_root data/coco/trainval_features --checkpoint_path saved_models_cp2/best_model.pth --output saved_models_cp2/result/
  • Compute detailed accuracy for each answer type:
python comput_score.py --input saved_models_cp2/result/XX.json --dataroot data/vqacp2/

Pretrained model

A well-trained model can be found here. The test results file produced by it can be found here and its performance is as follows:

Overall score: 61.91
Yes/No: 88.93 Num: 52.32 other: 50.39

    Questions about the code

    Thank you very much for providing the code, but I still have two questions that I did not understand well.

    1. A module, BDM, is used to capture negative bias, but this module only includes a multi-layer perceptron. Then how to ensure the features captured by this multi-layer perceptron are negative bias?
    2. On the left of Figure 2 of the paper, there are no backward gradient of the question-to-answer and the vision-to-answer branches. Where did it reflect in the code?

    CVE-2007-4559 Patch

    Patching CVE-2007-4559

    Hi, we are security researchers from the Advanced Research Center at Trellix. We have began a campaign to patch a widespread bug named CVE-2007-4559. CVE-2007-4559 is a 15 year old bug in the Python tarfile package. By using extract() or extractall() on a tarfile object without sanitizing input, a maliciously crafted .tar file could perform a directory path traversal attack. We found at least one unsantized extractall() in your codebase and are providing a patch for you via pull request. The patch essentially checks to see if all tarfile members will be extracted safely and throws an exception otherwise. We encourage you to use this patch or your own solution to secure against CVE-2007-4559. Further technical information about the vulnerability can be found in this blog.

    If you have further questions you may contact us through this projects lead researcher Kasimir Schulz.

    LXMERT numbers

    Hi, I wish to reproduce the LXMERT(LXMERT without D-VQA) numbers reported in the paper. It would be helpful if you could provide me with a way to do this using your code. I tried using the original LXMERT code, but I am not able to get the numbers reported in your paper on the VQA-CP2 dataset.

    您好，我将box的注释解开后，重新生成特征，然后将其绘制出来，但是明显感觉有偏差，不知道您是否可以提供一份绘图的代码。 image 下面是我的代码 def plot_rect(image, boxes): img = Image.fromarray(np.uint8(image)) draw = ImageDraw.Draw(img) for k in range(2): box = boxes[k,:] print(box) drawrect(draw, box, outline='green', width=3) img = np.asarray(img) return img def drawrect(drawcontext, xy, outline=None, width=0): x1, y1, x2, y2 = xy points = (x1, y1), (x2, y1), (x2, y2), (x1, y2), (x1, y1) drawcontext.line(points, fill=outline, width=width)
