Gradient overflow. skipping step loss scaler

WebUpdating the Global Step After the loss scaling function is enabled, the step where the loss scaling overflow occurs needs to be discarded. For details, see the update step logic of the optimizer. In most cases, for example, the tf.train.MomentumOptimizer used on the ResNet-50HC network updates the global step in apply_gradients, the step does ... 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, …
