Intro
I am getting TypeError: can not serialize 'BaseTextRank' object when trying to use spaCy's multiprocessing in nlp.pipe with a textrank pipeline component.
Sorry if this a known/expected feature/limitation - I couldn't find anything by searching repo. I generally find (spaCy's) multiprocessing a bit temperamental anyhow, but this seems to just not work.
PS. thanks for all the great work on the package!
Environment
Ubuntu 18.X (AWS DL AMI), Python 3.8 (via conda/mamba), pytextrank installed via pip, thtough conda - do let me know if you need more info.
Reproducible example - hopefullly
import spacy
import pytextrank
import en_core_web_sm
nlp = en_core_web_sm.load()
nlp.add_pipe("textrank", last=True);
txt = """

The First Book of Moses: Called Genesis
1:1 In the beginning God created the heaven and the earth.
1:2 And the earth was without form, and void; and darkness was upon
the face of the deep. And the Spirit of God moved upon the face of the
waters.
1:3 And God said, Let there be light: and there was light.
1:4 And God saw the light, that it was good: and God divided the light
from the darkness.
1:5 And God called the light Day, and the darkness he called Night.
And the evening and the morning were the first day.
