Question

您好我正在尝试scipy.weave.blitz以使我的代码更快，但它似乎没有工作，只是给出了一个神秘的编译错误。

import numpy as np
from scipy import weave

def algorithm(cities):

    order = np.array( range( cities.shape[0] ) )
    shuffle(order)
    length = calcLength(cities, order)
    start = time()

    changed = True
    while changed:

        changed = False

        for a in range(1, cities.shape[0]):

            for b in range(a+1, cities.shape[0]):

                new_order = np.zeros(order.shape)
                weave.blitz("new_order = order[:a] + order[a:b][::-1] + order[b:]")
                new_length = calcLength(cities, new_order)

                if new_length < length:
                    length = new_length
                    order = new_order
                    changed = True

    return order

和错误

很抱歉只是转发错误信息，但我不知道错误：/

scipy.weave编译错误没有意义
