For tensors, it returns a new copy on the GPU instead of rewriting the given tensor. Therefore, you usually do tensor = tensor.to(device). torch.nn also contains loss functions like nn.MSELoss. WebNov 21, 2024 · Watch on. In this PyTorch Tutorial we learn how to use a Learning Rate (LR) Scheduler to adjust the LR during training. Models often benefit from this technique once learning stagnates, and you get better results. We will go over the different methods we can use and I'll show some code examples that apply the scheduler. fitbit charge 5 vs inspire 2 reddit
