create_spans

act imperative

Return the byte start/end span corresponding to every token for supplied text with one model or several models, without changing the Tok·Show UI. Spans normally address the supplied input bytes. If a tokenizer normalizes its input first, spanInputs identifies the processed text whose bytes the spans address.
