How to do transfer learning with inception_v3?

[ptrblck]

inception_v3 was added in March 2017, so I’m not sure, if we are talking about the same model.

Anyway, the Finetuning Tutorial has specific code paths for the inception model and for its auxiliary outputs.

I see the term ‘logits’ being used very often but I struggle to make sense of it (i.e. I understand the difference between scores and probs after a softmax, not sure where logits and aux_logits fit in this schema).

Logits are basically the input to a softmax layer.
Since nn.CrossentropyLoss is using F.log_softmax and nn.NLLLoss internally, you don’t need to apply softmax manually.
