Python3: Geopy Nominatim() возвращает ошибку 503: служба недоступна. Используя Блокнот Юпитера

Question

Итак, у меня есть небольшой файл CSV, я пытаюсь геокодировать адреса в файле CSV. Тем не менее, я продолжаю получать следующую ошибку: я пытался увеличить время ожидания для Nominatim(), не помогло. Я получаю сообщение об ошибке 503: служба недоступна.

locator = Nominatim(timeout=20)
location = locator.geocode("3995 23rd St, San Francisco, CA 94114")
