I get the same error with CLAREAugmenter

I've changed the init params of Sentence in attacked_text.py
From:

sentence = Sentence(
    self.text, use_tokenizer=textattack.shared.utils.words_from_text
)

To:

sentence = Sentence(
    textattack.shared.utils.words_from_text(self.text), use_tokenizer=False
)

And it works like a charm

From PR #293-(Oct 6, 2020) , we send the function textattack.shared.utils.words_from_text for use_tokenizer in the pos_of_word_index function.

def pos_of_word_index(self, desired_word_idx):
    """Returns the part-of-speech of the word at index `word_idx`.
    Uses FLAIR part-of-speech tagger.
    """
    if not self._pos_tags:
        sentence = Sentence(
            self.text, use_tokenizer=textattack.shared.utils.words_from_text   <<< Function sent as Callable function.
        )
        textattack.shared.utils.flair_tag(sentence)
        self._pos_tags = sentence
    flair_word_list, flair_pos_list = textattack.shared.utils.zip_flair_result(
        self._pos_tags
    )

And as of PR "Major refactoring of internal label logic #2645" in the flairNLP Repo (Feb 11, 2022) in "https://github.com/flairNLP/flair/blob/master/flair/data.py" - Flair does not allow callable functions as input for the Sentence Class.

To follow Flair's implementation and fix the errors seen in Issues #642 and #638, we should revert PR "have flair use textattack tokenization method #293".

I can go ahead and submit a PR to revert PR #293 if it makes overall sense.

Can you please revert #293 if there is no other way to resolve #642 and #638?
