The number of GPUs used for retrieval tasks

[ghchen18]

Hi, thank you for your wonderful work.

I notice the world_size is used here when evaluating on the image-text retrieval task. How many GPUs do you use for the results in Table 1 and Table 2 of the paper? Do you use 8 GPUs to evaluate the model after it is fine-tuned with 8 GPUs?

Many thanks.
