I was getting this error
Can anyone help me out with this one?
Struggled with finding the classes/ys/labels (data.classes from fastai1) myself. Seems like in fastai2 (version 2.5.2) they are stored under the dataloader’s vocab like this:

vocab. Also I find the notebooks make it at times somewhat harder to “explore” than for example an IDE like PyCharm where I can easily step through code and see where stuff happens (in this case the resolution of labels). You seem to have found a good way through the library …
