Question

基于示例multiprocess using pathos and dill，我遇到了cPickle错误。我按www3cam做了;稍加一点..通过删除病毒，莳萝，多进程和pyreadline。然后在仔细删除上面提到的那些侧包后点击pip install pathos --no-cache-dir。新的安装，PC的冷启动以及后来的Anacoda2更新...带有cPickles的罐子......仍然在那里，Frank Zappa继续唱着他的＆＃34; Titties和Beer＆＃34;曲。

来自1的修改后的代码：

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import os, sys
import datetime, time
import multiprocessing
import pathos.pools as pp
import dill


class Multiprocess(object):

    def __init__(self):
        pass

    def qmp_worker(self,(inputs, the_time)):
        print " Processs %s\tWaiting %s seconds" % (inputs, the_time)
        time.sleep(int(the_time))
        print " Process %s\tDONE" % inputs

    def qmp_handler(self):                           # Non tandem pair processing
        pool = pp.ProcessPool(2)
        pool.map(self.qmp_worker, data)

def mp_worker((inputs, the_time)):
    print " Process %s\tWaiting %s seconds" % (inputs, the_time)
    time.sleep(int(the_time))
    print " Process %s\tDONE" % inputs
    sys.stdout.flush()

def mp_handler():                           # Non tandem pair processing
    p = multiprocessing.Pool(2)
    p.map(mp_worker, data)

def mp_handler_tandem():
    subdata = zip(data[0::2], data[1::2])
#    print subdata
    for task1, task2 in subdata:
        p = multiprocessing.Pool(2)
        p.map(mp_worker, (task1, task2))

#data = (['a', '1'], ['b', '2'], ['c', '3'], ['d', '4'])
data = (['a', '2'], ['b', '3'], ['c', '1'], ['d', '4'], 
        ['e', '1'], ['f', '2'], ['g', '3'], ['h', '4'])

if __name__ == '__main__':
    sys.stdout.flush()
#    print 'mp_handler():'
#    mp_handler()
#    print '---'
#    time.sleep(2)

#    print '\nmp_handler_tandem():'
#    mp_handler_tandem()
    print '---'
#    time.sleep(2)

    Multiprocess().qmp_handler()

也许应该像here＆＃34;捕捉和打印PyQt5追溯一样设置一些东西？

下面的片段代码让我思考并好奇是否需要为莳萝做这样的事情？

# Back up the reference to the exceptionhook
sys._excepthook = sys.excepthook

# Set the exception hook to our wrapping function
sys.excepthook = my_exception_hook
