Something about the training .

[linjing7]

Hi, thanks for your excellent work. I wonder that will it save some time if I change the "trainer_mode" from "dp" into "ddp"? I have 4 GPUs and it seems that it did not speed up ~

Yes, the ddp mode in this code repository cannot work correctly. It should be rewritten and the dataset in lmdb format will cause some problems.

Okay, I'll try to rewritte it.

Okay, I'll try to rewritte it.

Hi, could you share the rewritten ddp code？
