안녕하세요. 9장 질문입니다. 아래와 같은 에러가 발생했어요..

소스코드:

movies_df['genres_literal'] = movies_df['genres'].apply(lambda x : (' ').join(x))

count_vect = CountVectorizer(min_df=0, ngram_range=(1,2))

genre_mat = count_vect.fit_transform(movies_df['genres_literal'])

print(genre_mat.shape)

에러 코드:

InvalidParameterError                     Traceback (most recent call last)
