I can't install neuralcoref

[mandanafasounaki]

I get different errors every time I try to install the package. One of them is this on Google Colab when I use

pip install -e .

had same issue but resolved by downgrading cython to 0.29 (neither 0.28 nor 0.30 will work)

pip install cython==0.29 --upgrade

Thank you for the recommendation, but this is the output for installing cython 0.29:

same question

[Aryan-Deshpande]

yoo any update?

[guihuzhang]

yoo any update?

From my personal feeling of using this package, I think the solution is to downgrade the environment. It works for me with python3.7 and spacy 2.1
