[Tutor] newbie needs pypy setup tips

[eire1130 at gmail.com]

I think, but not 100 percent, that pypy has a list. You might get better traction there if you don't get a good *nswer here.

Although I have a couple questions. Have you profiled in python to look for hotspots?

Have you tried writting portions in c?

What kind of model is it, out of curiousity.

Subject: [Tutor] newbie needs pypy setup tips


I need advice about configuring pypy to run other python code. Why I ask:

I'm running a model implemented in python. Unfortunately a run on "straight" python 2.6.x or 2.7.x requires

- 130 min on my ubuntu laptop (on which working would be more convenient)
- 55 min on a better build machine on which I currently have access

However I have read that this model runs 5x faster under pypy, so I wanna get me that, but I'm finding the pypy docs pretty inscrutable. Nevertheless, I have managed to do

me at it:~$ uname -rv
> 2.6.32-33-generic #70-Ubuntu SMP Thu Jul 7 21:13:52 UTC 2011
me at it:~$ which pypy
> /usr/local/bin/pypy
me at it:~$ ls -al $(which pypy)
> lrwxrwxrwx 1 root root 37 2011-07-30 16:06 /usr/local/bin/pypy -> /opt/pypy-c-jit-1.5.0-alpha0/bin/pypy
me at it:~$ pypy --version
> Python 2.7.1 (b590cf6de419, Apr 30 2011, 02:00:34)
> [PyPy 1.5.0-alpha0 with GCC 4.4.3]

However, when I try to *really* run the @#$%^&! thing, it spews:

me at it:~$ pypy
> debug: WARNING: library path not found, using compiled-in sys.path and sys.prefix will be unset
> 'import site' failed
> Python 2.7.1 (b590cf6de419, Apr 30 2011, 02:00:34)
> [PyPy 1.5.0-alpha0 with GCC 4.4.3] on linux2
> Type "help", "copyright", "credits" or "license" for more information.
> debug: OperationError:
> debug:  operror-type: ImportError
> debug:  operror-value: No module named _pypy_interact

What do I need to do to fix its library path?
