WebSep 20, 2024 · 1 Answer. You can freeze your layer by setting the requires_grad to False: This way the gradients of the layer 's parameters won't get computed. Or by directly defining so when initializing the parameter: layer = nn.Linear (4, 1, bias=False) layer.weight = nn.Parameter (weights, requires_grad=False) Alternatively, given an input x shaped (n, 4 ... Webclass torch.optim.lr_scheduler.StepLR(optimizer, step_size, gamma=0.1, last_epoch=- 1, verbose=False) [source] Decays the learning rate of each parameter group by gamma every step_size epochs. Notice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr ...

WebMar 22, 2024 · To initialize the weights of a single layer, use a function from torch.nn.init. For instance: conv1 = torch.nn.Conv2d (...) torch.nn.init.xavier_uniform (conv1.weight) Alternatively, you can modify the parameters by writing to conv1.weight.data (which is a torch.Tensor ).
