WebUnder the hood, to prevent reference cycles, PyTorch has packed the tensor upon saving and unpacked it into a different tensor for reading. Here, the tensor you get from accessing y.grad_fn._saved_result is a different tensor object than y (but they still share the same storage).. Whether a tensor will be packed into a different tensor object depends on … Web🚧 1 fixed upstream failure:. These were probably caused by upstream breakages that were already fixed..

WebDec 22, 2024 · loss = loss_fun(out_softmax, labels_tensor) # step optim.zero_grad() loss.backward() optim.step() The issue I'm having as appearing above, is that the model learns to just predict one class (e.g., the first column above). Not entirely sure why it's happening, but I thought that penalizing more the prediction that should be 1 might help.
