Я загрузил пару текстовых файлов в кадры данных, используя pyspark, разделил их на слова и теперь хотел отфильтровать стоп-слова, используя StopWordsRemover .
Однако, когда я хочу создать экземпляр класса StopWordsRemover, он завершается с ошибкой:

Я попытался установить для параметра locale значение "en_US" или передать список stopWords, например, здесь - pyspark: как настроить StopWordsRemover с французским языком на искре 1.6.3
Я использую Spark v2.4.0.
