仅按行进行整洁的随机多维数组，保持列顺序不变

那

numpy.random.shuffle()

是为了：

>>> X = np.random.random((6, 2))>>> Xarray([[ 0.9818058 ,  0.67513579],       [ 0.82312674,  0.82768118],       [ 0.29468324,  0.59305925],       [ 0.25731731,  0.16676408],       [ 0.27402974,  0.55215778],       [ 0.44323485,  0.78779887]])>>> np.random.shuffle(X)>>> Xarray([[ 0.9818058 ,  0.67513579],       [ 0.44323485,  0.78779887],       [ 0.82312674,  0.82768118],       [ 0.29468324,  0.59305925],       [ 0.25731731,  0.16676408],       [ 0.27402974,  0.55215778]])
