James Burke added the comment: I'm also getting this error.
It appears to me to be caused by the length of the module name rather than case. mp_bug.py will run fine for me, but if I change it to mp_bug_longname.py then I will get this error. import multiprocessing import time class MP_Bug(multiprocessing.Process): def __init__(self): multiprocessing.Process.__init__(self) def run(test): for x in range(1, 10): print x time.sleep(1) if __name__ == '__main__': p = MP_Bug() p.start() ---------- nosy: +James.Burke _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue21614> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
