Я хочу вычислить косинусное сходство двух матриц, используя многопоточность
from sklearn.feature_extraction.text import CountVectorizer
count_vect = CountVectorizer()
df_series = count_vect.fit_transform(df.Series)
df_series.shape
from sklearn.feature_extraction.text import TfidfTransformer
tfidf_transformer = TfidfTransformer()
df_srtf = tfidf_transformer.fit_transform(df_series)
from sklearn.metrics.pairwise import cosine_similarity
SR=cosine_similarity(df_srtf)
