WebbHi Dai, CCA finds the vectors in x space and Y space that maximizes the correlation corr(u' X, v' Y), and continues finding such vectors under the constrain that (u_i)_i, (v_i)_i are orthogonal. As in your case dim Y = 1, you can only set n_components = 1: the vector v will be [1], and u will be the linear combination u that maximizes corr(u' X, Y).
