WebDec 1, 2024 · Skipping step, loss scaler 0 reducing loss scale to 0.0 Firstly, I suspected that the bigger model couldn’t hold a large learning rate (I used 8.0 for a long time) with “float16” training. So I reduced the learning rate to just 1e-1. The model stopped to report overflow error but the loss couldn’t converge and just stay constantly at about 9. WebDuring later epochs, gradients may become smaller, and a higher loss scale may be required, analogous to scheduling the learning rate. Dynamic loss scaling is more subtle (see :class:`DynamicLossScaler`) and in this case, …
