Accuracy = 0

[robd2]

Thank you so much @giannisnik for publishing this code. Is a very interesting use of a CNN. I'm trying to reproduce some of your results but keep getting Accuracy = 0 measurements. Any thoughts on where to focus my debugging? Maybe related to the missing "best model"?

just FYI, I think I've narrowed it down to the logic in the lambda function:
evaluation = lambda output, target: torch.sum(output.eq(target)) / target.size()[0]

Seems to be an issue with floor division if both operands have integer types. Maybe due to some recent PyTorch updates. Pull request submitted for proposed fix.
