Cross-Modal Contrastive Learning for Robust Reasoning in VQA

This repo is an implementation in PyTorch and supports METER, ViLT and ALBEF backbones.

Data preparation and pretrained models

Please follow METER and ViLT to prepare the datasets and download the pretrained checkpoints released by corresponding backbones.
