Unknown Morphological Feature

Question

Unknown Morphological Feature

StuartHewitson opened this issue 5 years ago · comments

I am trying to get up to speed with the model but when I execute the example code given I hit the following error when nlp = spacy.load("en_blackstone_proto") is called.

[E167] Unknown morphological feature: 'ConjType' (9141427322507498425). This can happen if the tagger was trained with a different set of morphological features. If you're using a pretrained model, make sure that your models are up to date:
python -m spacy validate

I have the same issue.
Check out this issue as reference: huggingface/neuralcoref#206
Can you update the model? It seems that it is not compatible with spacy right now.

Executing validation shows that it is not recognized as model at all:

Let me know if I can help somehow.

I'm guessing that as a quick workaround, for now, you could try downgrading your spaCy version to 2.1.8 orso ?

Downgrading to 2.1.8 works for me.

Apologies for the slow response to this issue @StuartHewitson and @Createdd. As @svlandeg says (thank you, Sophie), the current work around is to downgrade your spacy. Obviously, a workaround of this sort is not ideal.

We'll be retraining the model in November and we will not be initialising it with the pretrain command, which should make the model a bit more robust as new versions of spacy are released.

Are you using any language model from spacy you need to download the newer one

How exactly are you performing the downgrade?

I have run into this same issue and have yet to resolve it. pip install spacy==2.1.8 runs into an low level error while installing build dependencies...

pip install spacy==2.1.8

I'm on macOS Mojave 10.14.6.

Edit: this spacy issue got me pointed the right direction... the solution was to install with conda.

conda install -c conda-forge spacy=2.1.8
