Optimizer torch.optim.adam model.parameters

WebThe torch.optim package provides an easy to use interface for common optimization algorithms. Defining your optimizer is really as simple as: #pick an SGD optimizer optimizer = torch.optim.SGD(model.parameters(), lr = 0.01, momentum=0.9) #or pick ADAM optimizer = torch.optim.Adam(model.parameters(), lr = 0.0001) WebHave a question about this project?
