Question about Repeated Augmentation

See original GitHub issue

Hi, first of all, thank you for releasing the code base. I have a small question about the sampler for Repeated Augmentation. What does this 256*256 mean?

https://github.com/facebookresearch/deit/blob/cb29b5efd522a0ac83d64aa8b41fe27cead3a030/samplers.py#L32

Thank you!

I have tried to remove the RAsampler for deit-tiny and deit-small, the performance is almost the same.

Hi @moskomule ,

No it’s just to determine the number of images used in the dataset for each epochs. This is not exactly int(math.floor(len(self.dataset) / self.num_replicas)) but just the nearest multiple of 256. I think it was originally used for question of batch size.

Best,

Hugo
