Debug

Known issues

breakingnegspacy 1.x drops Python 3.6 support and is designed for spaCy 3.x. Ensure spaCy >=3.0 installed.

fix

Upgrade spaCy: pip install spacy>=3.0

affects: >=1.0.0

gotchaThe Negex component must be added after the entity recognizer (ner) in the pipeline; otherwise entities may not be recognized yet.

fix

Add pipe after 'ner': nlp.add_pipe('negex', after='ner')

affects: *

deprecatedUsing Negex(nlp, ...) constructor directly is deprecated; use nlp.add_pipe('negex', config={...}) instead.

fix

Use add_pipe pattern.

affects: >=0.1.0
