lmdb dataset

[koanho]

Hello, thank you for sharing your awesome work.

We are trying to use image features for the image data you provided, but when we downloaded the GQA, WIT, and NLVR2 datasets, they were recognized as files rather than folders due to the ".lmdb format". Can you please check this? It would be appreciated if you could supply .h5 or .npy files for the GQA, WIT and NLVR2 datasets.

Thank you.
