Hi there,

I am currently stuck trying to load a custom ner model trained using spacy 3.2.3 and spacy-transformers 1.1.6.

When loading the model into prodigy (prodigy-1.11.6-cp39-cp39-linux\_x86\_64.whl), I get the following error:

```python
ner_correct_compose-prodigy | catalogue.RegistryError: [E893] Could not find function 'spacy-transformers.Tok2VecTransformer.v3' in function registry 'architectures'. If you're using a custom function, make sure the code is available. If the function is provided by a third-party package, e.g. spacy-transformers, make sure the package is installed in your environment.

```

despite the fact that I my training config shows:

```python
[components.transformer.model]
@architectures = "spacy-transformers.TransformerModel.v1"
name = "roberta-base"

```

I am running Prodigy within a docker container which has python 3.9, spacy 3.1.3 (hopefully not causing issues for the model trained with 3.2.3), and spacy-transformers 1.1.4 installed.

Please help 🙏

Hi @BlakeList ,

There were [some changes in spacy-transformers from 3.1 to 3.2](https://spacy.io/usage/v3-2#spacy-transformers) and it may have affected how your model is being read, since you trained it in an earlier version. Is it possible to "copy" exactly your development and Docker environment? I presume this is mostly a library compatibility error.

Hi @ljvmiranda921

The issue was the prodigy version being 1.11.6 and not 1.11.7. But I will also upgrade spacy transformers.

Thanks,  
Blake
