I'm not sure this is directly fixable in the way you're looking for, since metrics in PyTorch need to be passed tensors, which can't be strings. And metrics are independent of Learners, at least for now. So making this all work transparently would require an API change - which isn't out of the question, but won't be added prior to the release of v2.
I've added documentation of this issue now, and also added a little helper method to make things easier (dl.vocab.map_objs(labels)
will give you the label indices to pass to the metric labels param). See 6acdeea
