Spacy-nightly (spacy 2.0) Issue With "thinc.extra.maxviolation Has Wrong Size"

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 i

Solution 1:

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
