Thanks a lot for answering.Accuracy is calculated as seperate function,and it is called in train epoch in the following loop: for batch_idx, (input, target) in enumerate (loader): output = model (input) # measure accuracy and record loss. batch_size = target.size (0) Webtorch.nn.functional.nll_loss. The negative log likelihood loss. See NLLLoss for details. K \geq 1 K ≥ 1 in the case of K-dimensional loss. input is expected to be log-probabilities. K \geq 1 K ≥ 1 for K-dimensional loss. weight ( Tensor, optional) – a manual rescaling weight given to each class. If given, has to be a Tensor of size C.
