Hi! It looks like the error here happens in Prodigy, since the latest stable version depends on spaCy v2.x. We just launched Prodigy nightly that updates Prodigy to spaCy v3 – you can sign up to test it here:
This version should also work with the sense2vec recipes out-of-the-box, although I haven't tested it yet. The good news is, none of sense2vec is really affected by the new stuff in v3, so the results will be the same and you could easily run it in a separate virtual environment, collect your terms, annotate your data, export it and then train with spaCy v3
