The function `dependency_labels_to_root(token)` defined in section *Get syntactic dependencies* does not terminate. Here is a complete example:
import spacy
nlp = spacy.load('en')
doc = nlp("Apple and banana are similar. Pasta and hippo aren't.")
def dependency_labels_to_root(token):
"""Walk up the syntactic tree, collecting the arc labels."""
dep_labels = []
while token.head is not token:
dep_labels.append(token.dep)
token = token.head
return dep_labels
dep_labels = dependency_labels_to_root(doc[1])
dep_labels
Replacing `is not` with `!=` solves the issue:
import spacy
nlp = spacy.load('en')
doc = nlp("Apple and banana are similar. Pasta and hippo aren't.")
def dependency_labels_to_root(token):
"""Walk up the syntactic tree, collecting the arc labels."""
dep_labels = []
while token.head != token:
dep_labels.append(token.dep)
token = token.head
return dep_labels
dep_labels = dependency_labels_to_root(doc[1])
dep_labels
The output is
['cc', 'nsubj']
