WebJul 18, 2024 · Encounter the same issue: the running_mean/running_var of a batchnorm layer are still being updated even though “bn.eval ()”. Turns out that the only way to freeze the running_mean/running_var is “bn.track_running_stats = False” . Tried 3 settings: bn.param.requires_grad = False & bn.eval () WebJun 8, 2024 · BatchNormalization contains 2 non-trainable weights that get updated during training. These are the variables tracking the mean and variance of the inputs. When you set bn_layer.trainable = False, the BatchNormalization layer will run in inference mode, and will not update its mean & variance statistics.
