You can see here. nn.CrossEntropy computes softmax internally.This is same as when we use softmax with nn.NLLLoss.

sure, I understand softmax exists there implicitly via error function formulation - what I do not see is logistic part of logistic regresstion

logistic sigmoid is just special case of softmax (when the number of class is 2). In multi-class classification task, we use softmax instead of sigmoid. This will help you.
