Hello, if i enable bidirectional decoder training script drops eror.
There is in train.py line 185
keep_avg.update_values({'avg_decoder_b_loss': loss_dict['decoder_backward_loss'].item(),
need to change on
keep_avg.update_values({'avg_decoder_b_loss': loss_dict['decoder_b_loss'].item(),

I'd like to train this model on 8 V100 GPUs - does it support multi GPU training?
