Re: NumPy, SciPy, & Python 3X Installation/compatibility issues
Hi EK, Did you figure out questions 1, 2 and 3? SciPy (0.14.0) on installation asks me for Python 2.7. First day on Python here, I am really struggling :/ Thanks, SK On Saturday, May 10, 2014 7:07:33 PM UTC+2, [email protected] wrote: > Hi All-- > > > > Let me state at the start that I am new to Python.

Why do you use python?
What would be your answer if this question is asked to you in an interview? a modified version might be: "Where would you use python over C/C++/Java?" (because my resume says I know C/C++/Java)? -- http://mail.python.org/mailman/listinfo/python-list
multiprocessing and freezing on Windows
Is there a method for freezing a Python 2.6 app using multiprocessing on Windows using PyInstaller or py2exe that works? It is trying to call my executable instead of python.exe when the process starts and passes it --multiprocessing-fork . Adding a freeze_support() to my main doesn't help. Do I have to bundle all of Python and use set_executable() to point to the bundled python.exe? I can't find any workable information on the canonical way to do this. Thanks! -- http://mail.python.org/mailman/listinfo/python-list
Re: multiprocessing and freezing on Windows
To add a bit more information, I found that I needed to patch get_command_line in multiprocessing/forking.py replacing: if getattr(sys, 'frozen', False): return [sys.executable, '--multiprocessing-fork'] else: prog = 'from multiprocessing.forking import main; main()' return [_python_exe, '-c', prog, '--multiprocessing-fork'] with: if WINEXE: prog = 'from multiprocessing.forking import main; main()' return [_python_exe, '-c', prog, '--multiprocessing-fork'] elif getattr(sys, 'frozen', False): return [sys.executable, '--multiprocessing-fork'] else: prog = 'from multiprocessing.forking import main; main()' return [_python_exe, '-c', prog, '--multiprocessing-fork'] and then using py2exe I can get a working "frozen" package if I include pythonw.exe and a subset of Python's Lib directory in my package and call multiprocessing.set_executable to point to that pythonw.exe. Does the above patch address a real bug? Is packaging with multiprocessing supposed to be this hard? If so, some documentation is needed. -- http://mail.python.org/mailman/listinfo/python-list

Thanks Gabriel. Posted as: http://bugs.python.org/issue6461 The multiprocessing author has tentatively confirmed the bug. -- http://mail.python.org/mailman/listinfo/python-list
