Unable to install neuralcoref : Coreference Resolution in spaCy with Neural Networks

Question

I am trying to install NeuralCoref using pip install neuralcoref. I already installed spaCy vesrion 3.0.6 and Visual Studio Build Tools version 16.9.5! However, I am still getting this error when running pip install neuralcoref:

  ERROR: Failed building wheel for neuralcoref

I also tried reinstalling Visual Studio and restarting and it also didnt work. Can someone help me with this issue?

Answer 1

The neuralcoref package only supports spaCy 2, so you'll need to downgrade spaCy to use it. I would recommend using 2.3.5, the latest v2 release.

Answer 2

For the accurate installation of neuralcoref : Coreference Resolution in spaCy with Neural Networks, below are the tested compatible versions in Ubuntu:

1. spacy==2.1.0
2. neuralcoref==4.0
