#=============================================# # 2.Basic autogard example2 # #=============================================# # Create tensors of shape (10,3) and (10,2) x = torch.randn(10, 3) y = torch.randn(10, 2) # Build a fully connected layer linear = nn.linear(3, 2) print('w:', linear.weight) print('b:', linear.bias) # Build loss function and optimizer loss = nn.MSELoss() optimizer = torch.optim.SGD(linear.parameters(), lr=0.01) Please help answer this question, thank you very much!
