What does requires_grad=False on BatchNorm2d perform?
WebThis helper function sets the .requires_grad attribute of the parameters in the model to False when we are feature extracting. By default, when we load a pretrained model all of the parameters have .requires_grad=True, which is fine if … WebMay 11, 2024 · Change require_grad to requires_grad: for param in model.parameters (): param.requires_grad = False for param in model.fc.parameters (): param.requires_grad = True Currently, you are declaring a new attribute for the model and assigning it to True and False as appropriate, so it has no effect.
