Why am I getting an import error upon importing multiprocessing?

multiprocessing, python, python-3.3, traceback

Solution

File "/usr/lib64/python3.3/tokenize.py", line 30, in <module>
    from token import *
File "/home/lucas/Server/ClinApp/weblabs/utils/token.py", line 1, in <module>
    from django.conf import settings

Your /home/lucas/Server/ClinApp/weblabs/utils/token.py script is being imported instead of the standard python 'token.py'. Its got a bug in it or it simply shouldn.t be imported as a top level script. You probably have /home/lucas/Server/ClinApp/weblabs/utils/ in your python path in some way.

Generally, its not a good idea to name python scripts after builtin scripts.

Problem

I have a script which requires multiprocessing. What I found from this script is that there is a problem with the multiprocessing module. To test this theory, I copied and pasted ``` from multiprocessing import Process def f(name): print('hello', name) if __name__ == '__main__': p = Process(target=f, args=('bob',)) p.start() p.join() ``` into a test script and received the following traceback ``` Traceback (most recent call last): File "a.py", line 1, in <module> from multiprocessing import Process File "/usr/lib64/python3.3/multiprocessing/__init__.py", line 40, in <module> from multiprocessing.util import SUBDEBUG, SUBWARNING File "/usr/lib64/python3.3/multiprocessing/util.py", line 16, in <module> import threading # we want threading to install it's File "/usr/lib64/python3.3/threading.py", line 11, in <module> from traceback import format_exc as _format_exc File "/usr/lib64/python3.3/traceback.py", line 3, in <module> import linecache File "/usr/lib64/python3.3/linecache.py", line 10, in <module> import tokenize File "/usr/lib64/python3.3/tokenize.py", line 30, in <module> from token import * File "/home/lucas/Server/ClinApp/weblabs/utils/token.py", line 1, in <module> from django.conf import settings File "/usr/lib/python3.3/site-packages/django/conf/__init__.py", line 9, in <module> import logging File "/usr/lib64/python3.3/logging/__init__.py", line 195, in <module> _lock = threading.RLock() AttributeError: 'module' object has no attribute 'RLock' ``` Also, I am running fedora 18 64-bit on a quad core ivy bridge. Why am I receiving this traceback error? Suggestion Here is what happens when I run RLock ``` $ python3 >>> import threading >>> threading.RLock() <_thread.RLock owner=0 count=0> >>> ```
