@BLP Yes, that’s due to spaCy v2.1.
We have a build of Prodigy that works with v2.1, but there’s one or two features we’d still like to add, especially pretraining support in the recipes. We also want to keep testing, as we want to make sure we give everyone a smooth experience.
Actually it would be useful to have some external testers as well. If you want to try it out, send us an email? contact@explosion.ai
