ModuleNotFoundError: No module named 'thinc.types'

How to reproduce the problem

I am working in a Jupyter notebook and do the following steps:

!pip install spacy==2.3.5
!python3 -m spacy download en_core_web_sm

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

I get the following stacktrace:

Which version of spacy_transformers do you have installed? And of thinc?

[narayanacharya6]

!pip list | grep spacy

spacy                         2.3.5
spacy-alignments              0.7.2
spacy-legacy                  3.0.1
spacy-transformers            1.0.1

!pip list | grep thinc
thinc                         7.4.1

NOTE: These were probably auto-installed as dependencies. Not something I installed separately.

[svlandeg]

Ah, that would explain it - spacy-transformers 1.x is compatible with spaCy v3, but not spaCy v2. You'll have to downgrade that lib to 0.6.2 (or uninstall it entirely if you don't use it anyway. You'd use it if you want to have transformer-based models in spaCy).

[narayanacharya6]

Whoops, understood. Downgrading spacy-transformers to 0.6.2 and restarting my notebook worked. Thanks for your time!
