After apparently successful installation of spacy-nightly (spacy-nightly-2.0.0a14) and english model (en_core_web_sm) I was still receiving error message during attempt to run it

import spacy
nlp = spacy.load('en_core_web_sm')

ValueError: thinc.extra.search.MaxViolation has the wrong size, try recompiling. Expected 104, got 128

I tried to reinstall spacy and model as well and it has not help. Tried it again within new venv (Python 3.6)

spacy nlp python

Issue is probably with thinc package, spacy-nightly needs thinc<6.9.0,>=6.8.1 but version 6.8.2 is causing some issues --> way how to solve it is run command bellow before you install spacy-nightly

pip install thinc==6.8.1

After this everything works perfectly fine for me.

I found later on that I am not the only one facing this issue https://github.com/explosion/spaCy/issues/1374
