pytorch固定部分参数 不用梯度 如果是Variable,则可以初始化时指定 j = Variable(torch.randn(5,5), requires_grad=True) 但是如果是m = nn.Linear(10,10)是没有requires_grad传入的 for i in m.parameters(): i.requires_grad=False 另外一个小技巧就是在nn.Module里,可以在中间插入这个 for p in self.parameters(): p.requi
In situation of finetuning, parameters in backbone network need to be frozen. To achieve this target, there are two steps. First, locate the layers and change their requires_grad attributes to be False. for param in net.backbone.parameters(): param.r
