What is "opt.times" for? #12

Closed JeremyCJM closed 1 year ago

Hi Mingyuan,

What is "opt.times" for? I see it is multiplied on the real dataset length in len() method, why do this? Why not just increase the epoch number?

Thanks, Jeremy

Initializing dataloader costs much time because it needs to build datasets for each worker. Therefore I just duplicate the dataset several times to reduce the number of dataloader initialization.

However, the usage of persistent_worker in the dataloader can significantly relief this situation. opt.times is then not necessary for current code.

I see, thanks.
