Hello there!

import spacy
import en_core_web_sm
nlp = en_core_web_sm.load()
from spacy.lemmatizer import Lemmatizer

Issue:

ModuleNotFoundError                       Traceback (most recent call last)
<ipython-input-35-1c9274a07301> in <module>

ModuleNotFoundError: No module named 'spacy.lemmatizer'

I cant downgrade to Spacy v2. Anyone find a correction? Is it an official issue in Sapcy? How works lemmatizer now in v3 please?

Thank you very much!
