singe GPU train

[yl-precious]

if I only have single GPU, how much performence without SyncBacthNorm will dorp ?, Simply to say, training on single GPU could achieve similar performance within +-1% error or not ?
should I adjust the learning rate to 1/8 of its orignal lr and set more epoch_num to get close result with orignal implements.
thanks!!!

Please refer to this issue #1 for your reference.
I haven't performed experiments with single GPU.
I think 1/8 lr and the same epoch would be a good start.
However it may take 4 days. Good luck.
