Kernel Died when running Neuralcoref - jupyter-notebook

Question

I am trying to install neuralcoref and following the instructions given here.
I created a jupyter notebook and try to run the following code.
# Load your usual SpaCy model (one of SpaCy English models)
import spacy
nlp = spacy.load('en')
# Add neural coref to SpaCy's pipe
import neuralcoref
neuralcoref.add_to_pipe(nlp)
# You're done. You can now use NeuralCoref as you usually manipulate a SpaCy
document annotations.
doc = nlp(u'My sister has a dog. She loves him.')
doc._.has_coref
doc._.coref_clusters
I get an error message from the jupyter, that kernel died. Even I try to run in the in a python file but still its not working.
O.S - Windows 10
RAM : 16GB
Note: I did try out to updating numpy but still it didn't worked.
Can anyone help me with that. Appreciate your time.
Thanks

Answer 1

As per here: https://github.com/huggingface/neuralcoref/issues/189.
You can get it to work fine if you downgrade Spacy to 2.1.0.
pip uninstall spacy
pip uninstall neuralcoref
pip install spacy==2.1.0
pip install neuralcoref --no-binary neuralcoref
Has worked for others, including myself. Notebook now runs fine.

Answer 2

There is no need to downgrade spacy at all. Build from source, because neuralcoref installed with pip is built against spacy==2.1.0.
Proof:
Build:
git clone https://github.com/huggingface/neuralcoref.git
cd neuralcoref
pip install -r requirements.txt # correct for the desired versions of Cython and SpaCy
python setup.py install
Test:
import spacy
import neuralcoref
nlp = spacy.load('en_core_web_md')
neuralcoref.add_to_pipe(nlp)
print(spacy.__version__)
doc = nlp(u'My sister has a dog. She loves him.')
print(doc._.has_coref)
print(doc._.coref_clusters)
2.3.2
True
[My sister: [My sister, She], a dog: [a dog, him]]
