Setup and Dependencies

We implemented our model using Python 3.7, PyTorch 1.11.0 (CUDA 11.3, CuDNN 8.3.2) and PyTorch Lightning. We recommend to setup a virtual environment using Anaconda.

1. Install git lfs on your system
2. Clone our repository to download a checpint of our best model and our code

   git lfs install
   git clone this_repo.git
   

3. Create a conda environment and install dependencies

   conda create -n olvit python=3.7
   conda activate olvit
   conda install pytorch==1.11.0 torchvision==0.12.0 torchaudio==0.11.0 cudatoolkit=11.3 -c pytorch
   pip install pytorch-lightning==1.6.3 
   pip install transformers==4.19.2
   pip install torchtext==0.12.0
   pip install wandb nltk pandas 
   

Download Data

1. DVD and SIMMC 2.1 data are included in this repository and will be downloaded using git lfs
2. Setup the data by executing

   chmod u+x setup_data.sh
   ./setup_data.sh
   

3. This will unpack all the data necessary in data/dvd/ and data/simmc/

Training

We trained our model on 3 Nvidia Tesla V100-32GB GPUs. The default hyperparameters need to be adjusted if your setup differs from ours.

DVD

1. Adjust the config file for DVD according to your hardware specifications in config/dvd.json
2. Execute

CUDA_VISIBLE_DEVICES=0,1,2 python train.py --cfg_path config/dvd.json

3. Checkpoints will be saved in checkpoints/dvd/

SIMMC 2.1

1. Adjust the config file for SIMMC 2.1 according to your hardware specifications in config/simmc.json
2. Execute

CUDA_VISIBLE_DEVICES=0,1,2 python train.py --cfg_path config/simmc.json

3. Checkpoints will be saved in checkpoints/simmc/

Testing

1. Execute

CUDA_VISIBLE_DEVICES=0 python test.py --ckpt_path <PATH_TO_TRAINED_MODEL> --cfg_path <PATH_TO_CONFIG_OF_TRAINED_MODEL>

Results

Training using the default config and a similar hardware setup as ours will result in the following performance

DVD

SIMMC 2.1
