Data Setup

We provide access to our preprocessed data (including extracted features) and preprocessing scripts to replicate our setup.

Preprocessed Data

• Conceptual Captions
• Flickr30k
• GQA
• MS COCO
• NLVR2
• RefCOCO (UNC)
• RefCOCO+ (UNC)
• RefCOCOg (UMD)
• SNLI-VE
• VQAv2

More recent (from IGLUE) and with more backbones:

• Flickr30K
• GQA
• MaRVL zero-shot | MaRVL few-shot
• NLVR2
• xFlickr&CO
• WIT

NB: I have noticed that uploading LMDB files made their size grow to the order of TBs. So, instead, I recently uploaded the H5 versions that can quickly be converted to LMDB locally using this script.

Preprocessing Steps

I originally relied on Hao Tan's airsplay/bottom-up-attention Docker image to extract image features from Faster R-CNN. For more details about the Docker image, see the LXMERT repository.

Recently, I have switched to Hao Tan's Detectron2 implementation of 'Bottom-up feature extractor', which is compatible with the original Caffe implementation. See here for step-by-step instructions.

Moreover, it is possible to extract Faster R-CNN features with a ResNeXt-101 backbone from the mmf repository following these instructions.
