我有一个GUI软件，我想在其中执行一些繁重的任务，因此我创建了新的子进程来运行这些任务。要做到这一点，我使用的是多处理模块，这在windows和unix上运行得非常好。但是，当我尝试相同的OSX 10.6进程崩溃发生时，我得到一个很长的错误报告，我无法破译。
以下是我用来制作子流程的内容： -
p = multiprocessing.Process(target = encode.encode , args = (self.path,self.savePath,) , name = "Encode Process")
p.start()
temp = wx.ProgressDialog('Please wait...', 'Encoding the File....This may take several minutes....\n\t....so sit back and relax....',parent = self,style = wx.PD_APP_MODAL | wx.PD_CAN_ABORT)
temp.SetSize((450,130))
while len(multiprocessing.active_children()) != 0:
time.sleep(0.1)
if not temp.UpdatePulse("Encoding the File....This may take several minutes...\n\tso sit back and relax.....")[0]:
p.terminate()
terminated = True
break
temp.Destroy()
p.join()
p.terminate()
以下是崩溃报告： -

我不确定问题是什么，因为它在windows和unix上运行得非常好。任何形式的帮助都表示赞赏。
编辑：我使用sudo再次运行它，这次没有崩溃，但另一方面没有进程启动，所以它没有任何区别。已经看过这个issue，但我应该如何解决这个问题？答案 0 :(得分：1)
确保子进程中没有任何内容尝试访问，创建或操作任何UI对象，包括位图或DC等内容。
