Webb所以,简短的回答是:使用distances = np.dot (movie_content, user_normalized.T)更复杂的答案是,点积仅针对两个矩阵定义X,并且Y如果第二个维度与X第一个维度匹配Y,即X具有形状 (M, N)和Y形状 (N, D)。. 点积的结果是一个维度为 的新矩阵 (M, D)。. 在您的情况下,您 … Webb19 juni 2024 · Mu_ = np.transpose (np.zeros ( (1,len (A)))) for i in range (len (A)): Mu_ [i] = mu. Mu_ is (11,1) matrix with mu in all slots. mu_ = A_-Mu_. mu_ = A_-mu would have worked just as well. No need to make Mu_. mu_ will have the same type and shape as A_. mu_t = np.transpose (mu_) No need to make mu_t (shape (1,11)).
