when i run code in window has an error not a valid win32 dll then i install scipy first in this site, then install numpy-mkl all python 2.7 and win32
http://www.lfd.uci.edu/~gohlke/pythonlibs/ then i run code below, got error , and captured screen in this link https://drive.google.com/file/d/0Bxs_ao6uuBDUQXROd2VqSURGa00/view?usp=sharing import numpy as np from scipy.sparse.linalg import svds from functools import partial from scipy.sparse import csr_matrix def emsvd(Y, k=None, tol=1E-3, maxiter=None): if k is None: svdmethod = partial(np.linalg.svd, full_matrices=False) else: svdmethod = partial(svds, k=k) if maxiter is None: maxiter = np.inf muhat = np.nanmean(Y, axis=0, keepdims=1) valid = np.isfinite(Y) Y_hat = np.where(valid, Y, muhat) halt = False ii = 1 v_prev = 0 while not halt: U, s, Vt = svdmethod(Y_hat - muhat) Y_hat[~valid] = (U.dot(np.diag(s)).dot(Vt) + muhat)[~valid] muhat = Y_hat.mean(axis=0, keepdims=1) v = s.sum() if ii >= maxiter or ((v - v_prev) / v_prev) < tol: halt = True ii += 1 v_prev = v return Y_hat, muhat, U, s, Vt A = csr_matrix([[1, 2, 0], [0, 0, 3], [4, 0, 5]]) emsvd(A) np.nanmean(A, axis=0, keepdims=1) -- https://mail.python.org/mailman/listinfo/python-list
