Setup and Dependencies

This code is implemented using PyTorch v1.0+, and provides out of the box support with CUDA 9+ and CuDNN 7+. Anaconda/Miniconda is the recommended to set up this codebase:

  1. Install Anaconda or Miniconda distribution based on Python3+ from their downloads' site.
  2. Clone this repository and create an environment:

git clone https://www.github.com/gicheonkang/sglkt-visdial conda create -n visdial-ch python=3.6 # activate the environment and install all dependenciesconda activate sglkt cd sglkt-visdial/ pip install -r requirements.txt # install this codebase as a package in development versionpython setup.py develop

Download Data

  1. We used the Faster-RCNN pre-trained with Visual Genome as image features. Download the image features below, and put each feature under $PROJECT_ROOT/data/{SPLIT_NAME}_feature directory. We need image_id to RCNN bounding box index file ({SPLIT_NAME}_imgid2idx.pkl) because the number of bounding box per image is not fixed (ranging from 10 to 100).
  • train_btmup_f.hdf5: Bottom-up features of 10 to 100 proposals from images of train split (32GB).
  • val_btmup_f.hdf5: Bottom-up features of 10 to 100 proposals from images of validation split (0.5GB).
  • test_btmup_f.hdf5: Bottom-up features of 10 to 100 proposals from images of test split (2GB).
  1. Download the pre-trained, pre-processed word vectors from here (glove840b_init_300d.npy), and keep them under $PROJECT_ROOT/data/ directory. You can manually extract the vectors by executing data/init_glove.py.
  2. Download visual dialog dataset from here (visdial_1.0_train.json, visdial_1.0_val.json, visdial_1.0_test.json, and visdial_1.0_val_dense_annotations.json) under $PROJECT_ROOT/data/ directory.
  3. Download the additional data for Sparse Graph Learning and Knowledge Transfer under $PROJECT_ROOT/data/ directory.

Training

Train the model provided in this repository as:

python train.py --gpu-ids 0 1 # provide more ids for multi-GPU execution other args...

Saving model checkpoints

This script will save model checkpoints at every epoch as per path specified by --save-dirpath. Default path is $PROJECT_ROOT/checkpoints.

Evaluation

Evaluation of a trained model checkpoint can be done as follows:

python evaluate.py --load-pthpath /path/to/checkpoint.pth --split val --gpu-ids 0 1

Validation scores can be checked in offline setting. But if you want to check the test split score, you have to submit a json file to EvalAI online evaluation server. You can make json format with --save_ranks True option.

Pre-trained model & Results

We provide the pre-trained models for SGL+KT and SGL.
To reproduce the results reported in the paper, please run the command below.

python evaluate.py --load-pthpath SGL+KT.pth --split test --gpu-ids 0 1 --save-ranks True

Performance on v1.0 test-std (trained on v1.0 train):
