      Save to tmp directory on non-chief workers in model_training_utils · 682d36b5
      Ran Chen authored 
      In a multi worker set up saving is done on each worker. If they're saving to the same location, e.g. GCS, there will be conflicts. With this change we save to temporary directory on non-chief workers.

Note that, there may be synchronization in saving that needs all workers to participate, so we cannot only save on one worker.

      Temporarily disable explicit allreduce in BERT SQuAD · 11ccb99e
      Zongwei Zhou authored 
      In BERT SQuAD, disable explicit allreduce for now to keep the original clip_by_global_norm math. With explicit allreduce, the gradients before allreduce are scaled so even if we move clip_by_global_norm before allreduce (as in TF1 and pre-TF 2.2) it will operate on scaled gradients, the math will be changed. So with explicit allreduce, it is better to move clip_by_global_norm to after allreduce.

    [BERT SQuAD] Enable mixed precision training

    Add mixed precision training support for BERT SQuAD model. Using the experimental Keras mixed precision API. For numeric stability, use fp32 for layer normalization, dense layers with GELU activation, etc.
