Building CNN on CIFAR-10 dataset using PyTorch: 1
WebThe combination of nn.LogSoftmax and nn.NLLLoss is equivalent to using nn.CrossEntropyLoss.This terminology is a particularity of PyTorch, as the nn.NLLoss [sic] computes, in fact, the cross entropy but with log probability predictions as inputs where nn.CrossEntropyLoss takes scores (sometimes called logits).Technically, nn.NLLLoss is … WebDec 13, 2024 · data, targets = get_batch (train_data, i) # Starting each batch, we detach the hidden state from how it was previously produced. # If we didn't, the model would try backpropagating all the way to start of the dataset. model. zero_grad if args. model == 'Transformer': output = model (data) output = output. view (-1, ntokens) else: hidden ... oris ssr
