Kernel dies on running doc = nlp(u"abc...xyz")

[Viole-Grace]

I'm using jupyter notebook on gcloud, with a venv for package installation. System image - Ubuntu 16.04

Steps to recreate the error :

pip3 install neuralcoref

and then

`import spacy
import neuralcoref

nlp = spacy.load('en')

neuralcoref.add_to_pipe(nlp)
doc = nlp(u'Deepika has a dog. She loves him. The movie star has always been fond of animals')
doc..coref_clusters
doc..coref_resolved

`
I get the following warning first :

/home/cloud/anaconda/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: spacy.tokens.span.Span size changed, may indicate binary incompatibility. Expected 72 from C header, got 80 from PyObject
  return f(*args, **kwds)

and then, the jupyter kernel dies.

I have tried building from source, following the readme for --no-binary as well, still the same issue persists. Kernel dies.

Any insight as to why this is happening / how to change any code to make it work would be much appreciated.

Thanks!

Hi!
I have found that the kernel doesnt die on pipelining, but on using any of the ._. functions from the doc. :
doc=nlp(u'I have a dog, and I love her.') doc._.coref_clusters
The code runs perfectly without any problems for :

import spacy import neuralcoref nlp = spacy.load('en') neuralcoref.add_to_pipe(nlp)

Any work around would be great, thanks!

kernel is dying on doc=nlp(u'I have a dog, and I love her.'). not with ._. functions.

[Viole-Grace]

kernel is dying on doc=nlp(u'I have a dog, and I love her.'). not with ._. functions.

Okay, but either way - any luck solving the problem?

Same problem here.

@Viole-Grace @vikrant094 Try to downgrade spacy to 2.1.0.

pip uninstall spacy 
pip uninstall neuralcoref
pip install spacy==2.1.0 
pip install neuralcoref --no-binary neuralcoref

That did the trick for me.

Thanks. It worked.

As a workaround for the incompatibility issue, you can indeed either downgrade spaCy to 2.1.0, or build neuralcoref from source if you want to use a more recent version of spaCy.

We plan on keeping the releases of neuralcoref and spaCy more in-sync in the future. Merging this with Issue #197.

pip uninstall spacy

pip install spacy==2.1.0

That did the trick for me.

As @fhopp mentioned his steps worked for me. But If you get an error like:
gcc: error trying to exec 'cc1plus': execvp: No such file or directory error: command 'gcc' failed with exit status 1
Then run sudo apt-get install g++ or the equivalent command in windows. I am working on Ubuntu.

@svlandeg solution (from source) also works. Following up on @kr-prince if you are on MAC OS and get the gcc error, you will likely need to download/update your MAC devtools.
