Multi Label Image Classification - Rename Labels Back

I’ve got a problem with a multi label image classification task. My dataset specifics is that each image has maaaany labels (20-100). So when I’m using dls.show_batch() all my labels are renamed (like a, b, c, d… etc.) - see example below

But how can I get real label names while using learn.predict()?

There was an error in my code that creates such the labels. Code works properly after fixes
