Retrieval time

[antoine77340]

Thank you so much for providing the code for UNITER, great work! The README mentions the following "NOTE: Image-Text Retrieval is computationally heavy, especially on COCO."

Do you have a rough estimation in mind of how many hours (or days) does it take to run the full text-to-image retrieval on COCO on 1 GPU (eg. Tesla V100).

Thanks for your help!

The size of val and test set on COCO is very large, conduct one evaluation with 8 GPUs (V100) needs 2~3hours. If you only evaluate on val and test set once after training, it will take more than 8 hours with 8 GPUs.
