使用Pandas和多处理模块时的属性错误

标签： python pandas multiprocessing

我是Python的新手，正在构建一个在后台进程中查询数据库的应用程序，然后将结果粘贴到pandas数据集中进行某些分析。我可以让分析和查询部分独立工作;但是，当我结合我的代码时，我得到以下错误（一直重复，直到我杀死程序）：

'module' object has no attribute 'day_abbr'

我读过的所有内容都可能是命名空间错误，我导入的模块具有共享相同名称的属性。我把它缩小到我对大熊猫和多处理模块的导入（即如果我用一个，但不是另一个它可以正常工作）。在线有很多例子可以成功导入这两个模块。我可以运行这些例子;然而，当我尝试做一些自定义的事情时，我无法让它发挥作用。我确定我错过了什么。下面是一些给我错误的代码示例。任何帮助将非常感谢！ 

import wx
import time

import sys

import pandas as pd
import multiprocessing as mp

def Worker():
    time.sleep(3)
    return [(1,2),(2,3),(4,5)]

class TheApp(wx.App):
     def OnInit(self):
         mainFrame = MainFrame(None, 'Test')
         mainFrame.Show()
         return True

class MainFrame(wx.Frame):

    def __init__(self, theParent, theTitle):
        wx.Frame.__init__(self, parent=theParent, title=theTitle, size=(200,200))
        self.Centre()
        myPanel = wx.Panel(self)
        self.myLabel = wx.StaticText(myPanel, -1, label="Start")

        pool = mp.Pool(4)
        pool.apply_async(func=Worker, callback=self.CallBackFunc)       

        #self.CallBackFunc([(1,2),(2,3),(4,5)])

    def CallBackFunc(self, returnValue):
        reader = pd.DataFrame.from_records(returnValue)
        self.myLabel.SetLabel(str(reader.get_value(1,1,True)))
        self.Refresh()           

if __name__ == "__main__":
    app = TheApp(False)
    app.MainLoop()
    sys.exit(0)
