py2exe with multiprocessing fails to run the proce

问题:

I am using Python 2.6 over windows 7 and I am trying to use multiprocess:

p = Process(target=f, args=(SOME_ARGS))
p.start()
p.join()

while I run the code from CMD (using the interpreter) everything works fine, but after I create an exe file with py2exe, the execution of the process fails with the following error:

error: no such option: --multiprocessing-fork

all the solutions I found did not help. any ideas?

回答1:

You know you are using a app of year 2008? (py2exe), python is in constant actualizations, and then gives problems with py2exe, I can give you a better solution...

You can use cxfreeze: http://cx-freeze.sourceforge.net/

Simply, easy, good, and actualized.

I hope this helped you.

You need a call to multiprocessing.freeze_support() when packaging a Python script into an executable for use on Windows. This call should come just after if __name__ == '__main__': before actually calling main()

Here is a great link that explains how to freeze your multiprocessing program to make it work with py2exe:

Namely, you will need to call multiprocessing.freeze_support() right after your call to main:

import multiprocessing

if __name__ == '__main__':
    multiprocessing.freeze_support()
