I have a dataset of reviews from TripAdvisor and I would like to translate non-English reviews into English.

The reviews are in many different languages: my dataset contains reviews in 44 different languages including English reviews which are around a quarter of the total, followed by Italian, German, Spanish and French reviews which are respectively 14%, 11% 6%, and 5.5% of the reviews.

I detect the different languages using the langdetect package.

from langdetect import detect

language = detect(title)

Then I tried to use the package googletrans to translate the text. However, when I tried to perform a small test I get the following error:

from googletrans import Translator
translator = Translator()

translator.translate('Buongiorno mi chiamo Alberto')

enter image description here

Does anyone know a way to translate reviews (knowing or not the language ) to English using python for a dataset of around 10k reviews?

This seems to be a known error in the package that can be solved by installing googletrans==4.0.0rc1 as mentioned in the github issue. This indeed seems to solves the issue when trying it myself:

from googletrans import Translator
translator = Translator()
translator.translate('Buongiorno mi chiamo Alberto').text
# Good morning my name is Alberto
