python

如何计算两列之间的余弦相似性？-python,python,cosine-similarity,Python,Cosine Similarity,我想得到st和pt的每一行之间的余弦相似性，并将其存储在df_all['similarity']中。对每一行使用scipy.distance.cosine（v1，v2） tfvect = TfidfVectorizer(use_idf=True, stop_words = 'english') wholeword = df_all['search_term']+" "+df_all['product_title'] vocab = tfvect.fit_transform(wholeword)

wholeword = df_all['search_term']+" "+df_all['product_title']
vocab = tfvect.fit_transform(wholeword)
st = tfvect.transform(df_all['search_term'])
pt = tfvect.transform(df_all['product_title'])
