运行Python服务时的特定错误

Question

我在PythonServiceExample.py中有一个Python服务代码

from Online_automated import *
import win32service
import win32serviceutil
import win32api
import win32con
import win32event
import win32evtlogutil
import os, sys, string, time

class aservice(win32serviceutil.ServiceFramework):

   _svc_name_ = "GPV"
   _svc_display_name_ = "GPV"
   _svc_description_ = "GPV"

   def __init__(self, args):
           win32serviceutil.ServiceFramework.__init__(self, args)
           self.hWaitStop = win32event.CreateEvent(None, 0, 0, None)           

   def SvcStop(self):
           self.ReportServiceStatus(win32service.SERVICE_STOP_PENDING)
           win32event.SetEvent(self.hWaitStop)                    

   def SvcDoRun(self):
      import servicemanager      
      servicemanager.LogMsg(servicemanager.EVENTLOG_INFORMATION_TYPE,servicemanager.PYS_SERVICE_STARTED,(self._svc_name_, '')) 

      #self.timeout = 640000    #640 seconds / 10 minutes (value is in milliseconds)
      self.timeout = 120000     #120 seconds / 2 minutes
      # This is how long the service will wait to run / refresh itself (see script below)

      while 1:
         # Wait for service stop signal, if I timeout, loop again
         rc = win32event.WaitForSingleObject(self.hWaitStop, self.timeout)
         # Check to see if self.hWaitStop happened
         if rc == win32event.WAIT_OBJECT_0:
            # Stop signal encountered
            servicemanager.LogInfoMsg("SomeShortNameVersion - STOPPED!")  #For Event Log
            break
         else:

                 #Ok, here's the real money shot right here.
                 #[actual service code between rests]
                 try:
                    print 'Im here'
                    rungpv()           #Execute the script


                 except:
                     pass
                 #[actual service code between rests]


def ctrlHandler(ctrlType):
   return True

if __name__ == '__main__':   
   win32api.SetConsoleCtrlHandler(ctrlHandler, True)   
   win32serviceutil.HandleCommandLine(aservice)

其中rungpv()在Online_automated.py中定义。我已经安装了该服务，该服务显示在Windows服务列表中。当我通过运行命令NET START GPV开始启动服务时，结果为

The GPV service could not be started.
A service specific error occurred: 1.

我该如何解决？ 我正在64位计算机上运行Python 32位版本。
