python多进程中多个参数函数的使用

from multiprocessing import Pool

from tqdm import tqdm

import numpy as np

import math

import time

from functools import partial

def func(x,y):

    time.sleep(0.1)

    return math.sin(x)+math.cos(y)

with Pool(processes = 20) as pool:

    result = list(tqdm(pool.imap(partial(func,y = math.pi), np.linspace(0,2*math.pi,1000)), total=1000))
