liaoxingyu 8f8cbf9411 fix lr scheduler warning when amp training
Skip lr scheduler when this iteration creates NaN gradients
2021-06-02 16:35:46 +08:00
liaoxingyu 256721cfde Impl `freezebb` in optimizer's step()
Make impl. of `freezebb` consistent with impl. of grad clip, and both are implemented through step() in optimizer
2021-05-31 17:15:26 +08:00
liaoxingyu 2b65882447 change way of layer freezing
Remove `find_unused_parameters` in DDP and add a new step function in optimizer for freezing backbone. It will accelerate training speed in this way.
