Best way to set an entirely custom stop words set

[probavee]

I can't set a full stop_word set by assigning it right after the model initialization

import spacy
nlp = spacy.load("fr_core_news_sm")
custom_stops = {"faire","un"}
nlp.Defaults.stop_words = custom_stops
print(nlp("faire")[0].is_stop) # False

import spacy
nlp = spacy.load("fr_core_news_sm")
custom_stops = {"faire","un"}
to_remove = set()
for stop in nlp.Defaults.stop_words:
    if stop not in custom_stops:
        to_remove.add(stop)
nlp.Defaults.stop_words.difference_update(to_remove)
nlp.Defaults.stop_words |= custom_stops
print(nlp("faire")[0].is_stop) # True

What if I want only my stopwords set? Is there a better way?

Defaults is a class, so if you modify the class after your pipeline has been created it doesn't matter, because there's already an instance with the old data. You need to modify the defaults before you create the pipeline, like this.

import spacy
from spacy.lang.fr import FrenchDefaults

FrenchDefaults.stop_words = something
nlp = spacy.blank("fr")
