Hi, for the long-term anticipation task, the paper says Damerau-Levenshtein distance is used for evaluation but the official code uses editdistance package, where only the Levenshtein distance is implemented, with transposition operation missing.

>>> import editdistance
>>> editdistance.eval([1, 2], [2, 1])
2

So for the online evaluation, which edit distance can we assume will be used there?

The evaluation server also uses Levenshtein distance from the editdistance package.
