WebBy default, PyTorch initializes weight and bias matrices uniformly by drawing from a range that is computed according to the input and output dimension. PyTorch’s nn.init module provides a variety of preset initialization methods. net = nn.Sequential(nn.LazyLinear(8), nn.ReLU(), nn.LazyLinear(1)) X = torch.rand(size=(2, 4)) net(X).shape WebWhen a module is created, its learnable parameters are initialized according to a default initialization scheme associated with the module type. For example, the weight …
