This is the implementation of the framework described in the paper:
Emanuele Bugliarello, Ryan Cotterell, Naoaki Okazaki and Desmond Elliott. Multimodal Pretraining Unmasked: A Meta-Analysis and a Unified Framework of Vision-and-Language BERTs. Transactions of the Association for Computational Linguistics 2021; 9 978–994.
We provide the code for reproducing our results, preprocessed data and pretrained models.
- 09-2021: Added code for
cross-modal ablation(Frank et al., EMNLP 2021) [Original code]
You can clone this repository with submodules included issuing:
git clone [email protected]:e-bug/volta
1. Create a fresh conda environment, and install all dependencies.
conda create -n volta python=3.6
conda activate volta
pip install -r requirements.txt
2. Install PyTorch
conda install pytorch=1.4.0 torchvision=0.5 cudatoolkit=10.1 -c pytorch
3. Install apex. If you use a cluster, you may want to first run commands like the following:
module load cuda/10.1.105
module load gcc/8.3.0-cuda
4. Setup the refer submodule for Referring Expression Comprehension:
cd tools/refer; make
5. Install this codebase as a package in this environment.
python setup.py develop
Check out data/README.md for links to preprocessed data and data preparation steps.
Check out MODELS.md for links to pretrained models and how to define new ones in VOLTA.
Model configuration files are stored in config/.
We provide sample scripts to train (i.e. pretrain or fine-tune) and evaluate models in examples/. These include ViLBERT, LXMERT and VL-BERT as detailed in the original papers, as well as ViLBERT, LXMERT, VL-BERT, VisualBERT and UNITER as specified in our controlled study.
Task configuration files are stored in config_tasks/.
