当我尝试使用此import pandas as pd
import pickle
import numpy as np
import multiprocessing
from 'function file' import function
file = 'file_name'
PKL_paths = 'path'
D = pd.read_pickle(PKL_paths + file)
S = range(0,361, 45)
if __name__ == '__main__':
a = multiprocessing.Process(target=function, args=(S[0], S[1], 1))
b = multiprocessing.Process(target=function, args=(S[1], S[2], 2))
c = multiprocessing.Process(target=function, args=(S[2], S[3], 3))
d = multiprocessing.Process(target=function, args=(S[3], S[4], 4))
e = multiprocessing.Process(target=function, args=(S[4], S[5], 5))
f = multiprocessing.Process(target=function, args=(S[5], S[6], 6))
g = multiprocessing.Process(target=function, args=(S[6], S[7], 7))
h = multiprocessing.Process(target=function, args=(S[7], S[8], 8))
i = multiprocessing.Process(target=function, args=(S[0], S[1], 1))
j = multiprocessing.Process(target=function, args=(S[1], S[2], 2))
k = multiprocessing.Process(target=function, args=(S[2], S[3], 3))
l = multiprocessing.Process(target=function, args=(S[3], S[4], 4))
m = multiprocessing.Process(target=function, args=(S[4], S[5], 5))
n = multiprocessing.Process(target=function, args=(S[5], S[6], 6))
o = multiprocessing.Process(target=function, args=(S[6], S[7], 7))
p = multiprocessing.Process(target=function, args=(S[7], S[8], 8))
a.start()
b.start()
c.start()
d.start()
e.start()
f.start()
g.start()
h.start()
i.start()
j.start()
k.start()

感谢您的答复，但事实证明我的macOS ruby / gems没有更新。我更新了所有必需的内容，并按照相同的步骤进行操作，现在一切正常。
