ImportError: cannot import name ReLu

Hi, I’m running into the following problem when to run any of prodigy command. The following is my system.

OSX 10.13 (High Sierra)
Anaconda Python 3.5
The latest Prodigy

Thanks for the report and sorry about that! I think we might have not specified the version pin for spaCy and Thinc (spaCy’s machine learning library) explicitly enough, so it seems to have fetched the latest version released yesterday. Just working on an update to Prodigy that fixes this.

In the meantime, could you try downgrading spaCy to the previous version? This should make it work again.

pip uninstall spacy-nightly
pip install spacy-nightly==2.0.0a14

I tried what you suggested, and encountered another error

Ah damn – this is an error that we initially tried to fix with the recent update to spaCy and Thinc. Looks like this is the same problem described in this thread – can you try downgrading Thinc to 6.8.1?

pip uninstall thinc
pip install thinc=6.8.1

Sorry again We’re currently working hard on getting an update ready for both spaCy and Prodigy that resolves those compatibility issues.

I deleted the previous post because I see the following bug. Seems like thorough update would be needed. I can wait so don’t worry

command

prodigy dataset gh_issues "Classify issues on GitHub"
prodigy textcat.teach gh_issues en_core_web_sm "docs" --api github --label DOCUMENTATION

Just sent out an update for Prodigy, v0.3.0, that should now be fully compatible with the latest spaCy alpha version!

Finally it works! Thanks!
