[Bug]: TypeError: 'type' object is not subscriptable

Issue

I've gone through the installation steps for dependencies as outlined in your readme document, yet I'm facing the issue
about "TypeError: 'type' object is not subscriptable" . ** I had installed all the requires** , but it did not worked. My python version is 3.8.13. I would greatly appreciate your assistance ！

`from typing import List

async def _infer(self, from_lang: str, to_lang: str, queries: List[str]) -> List[str]:
if from_lang == 'auto':
detected_lang = langid.classify('\n'.join(queries))[0]
target_lang = self._map_detected_lang_to_translator(detected_lang)

    if target_lang == None:
        self.logger.warn('Could not detect language from over all sentence. Will try per sentence.')
    else:
        from_lang = target_lang

return [self._translate_sentence(from_lang, to_lang, query) for query in queries]

`
this code can work

[AI-confused]

List[str] modify to List
this can work
