I am trying to compute cross_entropy loss manually in Pytorch for an encoder-decoder model. I used the code posted here to compute it: Cross Entropy in PyTorch I updated the code to discard padded tokens (-100). The final code is this: To verify that it works fine, I tested it on a text generation task, and I…

pytorch custom loss function nn.CrossEntropyLoss
After studying autograd, I tried to make loss function myself. And here are my loss and I compared with torch.nn.CrossEntropyLoss here are results values were same. I thought, because those are different functions so grad_fn are different and it won’t cause any problems. But something happened! After 4 …
