fijal / jitpy Goto Github PK

Visual Studio link.exe is raising an error with exit status 1181

I had to change some code on https://github.com/fijal/jitpy/blob/master/jitpy/__init__.py#L41:

    if not pypy_home.join('libpypy-c.so').check():
        libdir = pypy_home.join('bin')
        if not libdir.join('libpypy-c.so').check():
            libdir = pypy_home.join('pypy', 'goal')
            if not libdir.join('libpypy-c.so').check():
                raise Exception("Can't find libpypy-c.so, point PYPY_HOME to "
                                "directory with libpypy-c.so")

where I think libpypy-c.so should be libpypy-c.dll for the windows case.

After that I get an error on https://github.com/fijal/jitpy/blob/master/jitpy/__init__.py#L55

ffi.verify(...) would need another parameters for windows?

Maybe I'm wrong as I'm far of a good knowledge of c and compilers.

Kind regards.

may I ask which module is this?

Hi,

I really love pypy and jitpy, but for my work, I need to pass complex arguments to pypy functions, not just ints or strings.
So my solution is to convert everything into strings with pickle. Of course it a very dirty hack, but my code still runs many,many times faster than python :-)

It would be great if jitpy could handle all this directly, with some kind of decorator. Unfortunately I don't have enough python/pypy expertise to customize jitpy.
Here is the code I use to send/receive pickled strings.

from jitpy import setup
setup('/opt/pypy-2.5.0-linux/bin')
from jitpy.wrapper import jittify
import pickle
from cffi import FFI

@jittify([str],str)
def func(_pypy_arg):
    import pickle
    from cffi import FFI
    ffi = FFI()
    args = pickle.loads( ffi.string(_pypy_arg) )

    ret = "Processing "+str(args)+" and we're done..."

    return ffi.new("char[]",pickle.dumps(ret))


ffi = FFI()
_ret = func( pickle.dumps(["go",4,"it !!!"]))
print pickle.loads( ffi.string(_ret) )

Best regards,
Yann

It's looking for a .so but on OSX it's a dylib:
Traceback (most recent call last): File "al_csa_numpy.py", line 28, in <module> setup('/Users/rickvipond/Sites/pypy_binaries/pypy2-v5.7.1-osx64/bin/pypy') File "/Users/rickvipond/.virtualenvs/coachfairer/lib/python2.7/site-packages/jitpy/__init__.py", line 48, in setup raise Exception("Can't find libpypy-c.so, point PYPY_HOME to " Exception: Can't find libpypy-c.so, point PYPY_HOME to directory with libpypy-c.so

Changing the code to dylib spawns a new error

Thoughts?

I'm win10 64bit user and i run your code as below

from jitpy.wrapper import jittify
@jittify([int, float], float)
def func(count, no):
s = 0
for i in range(count):
s += no
return s
func(1000, 1.2)

but it has an error as follows. why is that? cuz am i using 64bit windows?
