This is a simple question but better safe than sorry! My understanding is that the
transformers class of models (for text classification) can only deal with integer labels as classes.
So it’s up to the user to provide a mapping between labels and scores. In the usual example one could have
0 = negative,
1 = neutral,
2 = positive.
Here is the basic question: do the numeric scores necessarily need to be integers from 0 to N (the number of classes) or I can use any other numbers of my liking?
