An AttributeError is raised when starting a new process with an object defined in the interactive interpreter
>>>def test():print "test"
>>>test()
test
>>>from threading import Thread
>>>Thread(target=test).start()
test
>>>from multiprocessing import Process
>>>Process(target=test).start()
<traceback, ending with>
File <path to python>/Lib/pickle.py, line 1126, in find_class
klass = getattr(mod, name)
AttributeError: 'module' object has no attribute 'test'
running similar code in a file works and does not raise an error.

I'm guessing you are on Windows. Please read https://docs.python.org/2/library/multiprocessing.html#windows. You can't do what you show on windows (though you can on unix, since it uses fork). |
