Data & Pre-trained Models

Download preprocessed data and our pre-trained models by visiting OneDrive. We suggest following our data structures, which is consistent with the paths in config.py. You may need to modify the root_path in config.py. In addition, please following the instructions to prepare some other data:

• Download grid features in path data/grid_features provided by X-LXMERT or follow feature extraction to extract these features.

  wget https://ai2-vision-x-lxmert.s3-us-west-2.amazonaws.com/butd_features/COCO/maskrcnn_train_grid8.h5 -P data/grid_features
  wget https://ai2-vision-x-lxmert.s3-us-west-2.amazonaws.com/butd_features/COCO/maskrcnn_valid_grid8.h5 -P data/grid_features
  wget https://ai2-vision-x-lxmert.s3-us-west-2.amazonaws.com/butd_features/COCO/maskrcnn_test_grid8.h5 -P data/grid_features
  

• For text-to-image evaluation on MSCOCO dataset, we need the real images to calculate the FID metric. For UMT-DBITG, we use MSCOCO karpathy split, which has been included in the OneDrive folder (images/imgs_karpathy). For UMT-BITG, please download MSCOCO validation set in path images/coco_val2014.
