我有一些代码，我按如下方式生成索引：
import numpy as np
from multiprocessing import Pool
def compute(idx, ix, kx, im, f):
im[idx[0], idx[1]] = func1([[ix[0], ix[1]]])
f[idx[0], idx[1]] = func2([[kx[0], kx[1]]])[0]
N = 256
max_k = 32
g = np.zeros(N, N)
k = np.zeros(N, N)
# These will be used to generate some indexes and sampling points
ix = np.linspace(-1, 1, N)
iy = np.linspace(-1, 1, N)
kx = np.linspace(-max_k, max_k, N)
ky = np.linspace(-max_k, max_k, N)
p = Pool()
for idy, yi, yf in zip(count(), iy, ky):
for idx, xi, xf in zip(count(), ix, kx):
p.apply_async(compute,args=([idx, idy], [xi, yi], [xf, yf],
g, k))
p.close()
p.join()
此处func1和func2是一些被调用的函数。现在，当我运行这个时，我得到了大量的错误，基本上要点如下：
