easyAI-checkedPyTorch

A skin-lesion classifier has seven classes (MEL, NV, BCC, AKIEC, BKL, DF, VASC) and is trained with nn.CrossEntropyLoss on logits of shape (N, 7). Which target tensor is the standard choice?

A LongTensor of shape (N,) holding class indices from 0 to 61
A LongTensor of shape (N,) holding class indices from 1 to 72
A Python list with the class names, such as 'MEL'3
A FloatTensor of shape (N,) holding $k/6$ for class $k$ 4
