海量高维向量最近邻遇到的问题

1.

for i in range(0, 10):
    X1 = X[i*100000:i*100000+100000]
    clf = NearestNeighbors(n_neighbors=1,algorithm='ball_tree',metric='euclidean')
    clf.fit(X)
    clfSet.append(clf)
    filename = 'finalized_model.sav' + i
    pickle.dump(clf, open(filename, 'wb'))

第6行有错，字符串和数字相加出错  改为str(i)
