Approach 2: tf_vectorizer = CountVectorizer (max_features=n_features, stop_words='english') tf = tf_vectorizer.fit_transform (data_samples) lda = LatentDirichletAllocation (n_topics=n_topics, max_iter=5, learning_method='online', learning_offset=50., random_state=0) lda_x=lda.fit_transform (tf) in the first approach, there is no fit_transform . I've also tried things like: vectorizer = sklearn.feature_extraction.text.CountVectorizer (min_df=0,max_df = 3, lowercase = False, stop_words = 'english', analyzer='word') X = TIP_with_rats ['s_lemmas_IP'].apply (vectorizer.fit_transform) Which doesn't kick back an error but also doesn't return anything. I guess the same would be true in the stacking example, has I expect TfidfVectorizer to delivers that. Somewhere in your code, it tries to lower case integer object which is not possible. これはコードです: zkey = 'test' k = 15648 nval = '15648-barry' redis.zadd (zkey, k, nval) これはエラーです .
