Hi folks,  
I updated from prodigy 1.4.0 prodigy 1.4.1 and I started getting this error whenever I tried to load a my spacy model with custom word vectors:

```python

I tried rebuilding my environment with 1.4.0 but I’m seeing the same regression. I’m guessing another library changed. I had an old copy of my environment where this error is not occurring and here is the diff in the output of `pip freeze`:

```python
diff pip.old pip.new
13d12
< ftfy==4.4.3
15d13
< html5lib==1.0b8
39c37
< spacy==2.0.10
---
> spacy==2.0.11
43c41
< tqdm==4.19.8
---
> tqdm==4.21.0
47d44
< wcwidth==0.1.7

```

Based on this I’m guessing this is a regression with `spacy==2.0.11`? I’ll try to see if I can downgrade to `spacy==2.0.10` to address the issue…

**UPDATE** : I’ve verified that downgrading spacy to 2.0.10 addresses this regression.

Interestingly it looks like a very similar issue was fixed in an older version of spacy (v2.0.6) but is now back again? [https://github.com/explosion/spaCy/issues/1727](https://github.com/explosion/spaCy/issues/1727)

@beckerfuffle Hmm! Sorry about this. This relates to a recent fix in v2.0.11: [https://github.com/explosion/spaCy/issues/1660](https://github.com/explosion/spaCy/issues/1660)

There’s currently a deprecation fix in place that’s supposed to allow the current code to work with the existing models, which don’t declare the vectors properly in the cfg files. I think this deprecation fix is what’s causing the current error.

Would you be able to paste the contents of the `tagger/cfg` and `meta.json` files in your model? It’s difficult to figure out exactly where this is going wrong without seeing which code-path is being followed, and I’m not sure exactly how the model was built.

Just a reminder that I built this model using the core\_web\_sm model as a base [Loading gensim word2vec vectors for terms.teach?](https://support.prodi.gy/t/loading-gensim-word2vec-vectors-for-terms-teach/333/3) :

tagger/cfg

  "cnn_maxout_pieces":2,
  "pretrained_dims":0
}

Thanks! I think I see the problem. I bet I’m checking whether the `pretrained_dims` key exists somewhere, instead of checking the value isn’t 0.

@beckerfuffle Just upload a new dev build. Would you mind doing `pip install spacy==2.0.12.dev0` and checking it resolves the problem?

Yup that fixed it! I’ll use `2.0.12.dev0` for now!
