python - TypeError: Argument 'string' has incorrect type (expected str, got float)

Question

I am working on a code for aspect extraction. I was getting the following error. can anyone help me resolve this ?

aspect_terms = [] for review in nlp.pipe(df2.review): chunks = [(chunk.root.text) for chunk in review.noun_chunks if chunk.root.pos_ == 'NOUN'] aspect_terms.append(''.join(chunks))

TypeError: Argument 'string' has incorrect type (expected str, got float).

Answer 1

Covert chunk.root.text to a string during list comprehension. .join requires strings in the iterable.

aspect_terms = [] 
for review in nlp.pipe(df2.review):
    chunks = [str(chunk.root.text) for chunk in review.noun_chunks if chunk.root.pos_ == 'NOUN']
    aspect_terms.append(''.join(chunks))
