What does this PR do?
As #8958 pointed out, the current way labels are computed in the
run_nerscript using offset mappings does not work for sentencepiece-based tokenizers. This PR fixes that using the.word_idsmethod which is more elegant and more reliable.In passing it adds an early check that the tokenzier is fast (otherwise the script just doesn't work).
