About `disable_dbsampler`

Hi, I succesfully reproduced base centerformer 68.06 in nuscenes. Thanks a lot.

One thing I have noticed difference from CenterPoint base code is, you code contains disable_dbsampler option. Could you explain what's the motivation of this part? Is it simply turning off augmentation from epoch 15?

This is a training trick introduced by Pointaugmenting and is commonly used in most recent papers. Basically, the final performance is better if we disable the copy & paste augmentation in the last few epochs. I actually have not tried numbers other than 15 in my experiments.
