WebParameters: weight ( Tensor, optional) – a manual rescaling weight given to the loss of each batch element. If given, has to be a Tensor of size nbatch. size_average ( bool, optional) – Deprecated (see reduction ). By default, the losses are averaged over each loss element in … WebOct 11, 2024 · Pytorch CrossEntropyLoss Supports Soft Labels Natively Now Thanks to the Pytorch team, I believe this problem has been solved with the current version of the torch CROSSENTROPYLOSS. You can directly input probabilities for each class as target (see the doc). Here is the forum discussion that pushed this enhancement. Share Follow
