could you please tell me the relationship of batch_size, epoch, iteration, and samples_per_gpu? And how to set them?

I think there must be a calculation method between the values such as batch_size, epoch and Iteration. I am also interested in this calculation method. Looking forward to an official reply!

In mmdet, samples per gpu * GPUs = batch size epoch is training epoch, that you are setting total_iteration per epoch = total_sample / batch_size
