Is it possible to apply Negspacy over token?

[Raghu17s]

Hi,

How can I apply negations on the token? is it possible?

I tried following but it ended up in error.
`for token in doc:

print(token.text, token._.negex)

The error is

AttributeError Traceback (most recent call last)
in
1 for token in doc:
----> 2 print(token.text, token._.negex)

~/anaconda3/envs/python3/lib/python3.6/site-packages/spacy/tokens/underscore.py in getattr(self, name)
33 def getattr(self, name):
34 if name not in self._extensions:
---> 35 raise AttributeError(Errors.E046.format(name=name))
36 default, method, getter, setter = self._extensions[name]
37 if getter is not None:

AttributeError: [E046] Can't retrieve unregistered extension attribute 'negex'. Did you forget to call the set_extension method?

Unfortunately, no as it is an extension for "spans" only.
