Pytorch batchnorm layer
WebFeb 19, 2024 · The BatchNorm layer calculates the mean and standard deviation with respect to the batch at the time normalization is applied. This is opposed to the entire … WebNov 4, 2024 · I would guess that your training might set the batchnorm layers or the entire model into .eval () mode so that the running stats are never updated and keep their initial values. Check your code for .eval () calls (additionally also for self.training = False assignments) and see if that might be the issue.
