AttributeError: module 'neuralcoref' has no attribute 'neuralcoref'

For the code -
```python
import spacy
nlp = spacy.load('en_core_web_sm')

import neuralcoref
coref = neuralcoref.neuralcoref.NeuralCoref(nlp.vocab)
nlp.add_pipe(coref, name='neuralcoref')
```

I am getting the following error -
```bash
coref = neuralcoref.neuralcoref.NeuralCoref(nlp.vocab)
AttributeError: module 'neuralcoref' has no attribute 'neuralcoref'
```

Strangely, the code was working fine earlier with the virtual environment but now I am starting to get this error.

I am using `python v3.6.8` on Linux and my `requirements.txt` is -
