Question when use apex

[South-Twilight]

Hi, when I use apex to train a model on 4 gpus and batch_size=16 in config.yaml, the train.log shows below:

[train]:   6%|▋         | 157283/2500000 [00:07<5077:11:43,  7.80s/it]

I'm not sure that the checkpoint-150000steps.pkl means train the model
either 150000*4=600000steps && batch_size=16 or 150000steps && batch_size=16*4=64 .

I'm looking forward to your reply.

150000steps && batch_size=16*4=64

This one.

Thanks a lot.
