：
モジュール関数がでdefiinedさは、それは、Pythonの実行中のすべてのバージョンに存在する
'__main__'
と呼ばれています。
ソース広場アウトや、できるだけメインモジュールは限り短くします：
# main.py
def square(x):
return x**2
import Pyro4
def main():
remoteServer = Pyro4.Proxy('PYRONAME:server')
print remoteServer.evaluate(square, 4)
漬物はそうあなたは二つの可能性を持っているソースコードが、参照
__main__.square
を転送しません。
と：
その後、サーバーはファイルからまったく同じモジュールをインポートできます。
または私のコードでモジュールを作成します。その後、
class ThisShallNeverBeCalledError(Exception):
pass
class _R(object):
def __init__(self, f, *args):
self.ret = (f, args)
def __reduce__(self):
return self.ret
def __call__(self, *args):

ret = cls(None)
ret.ret = value
return ret
def dump_and_load(obj):
'''pickle and unpickle the object once'''

R(R(PICKLABLE_FunctionType, code, globals)),
R(R(getattr, type(globals), 'get'), globals, \

return obj
と反対側にこれを送る：
packCode('''
def square(...):
...
''', return_value_variable_name = 'square')
と機能は反対側に出てくるだろう、何のモジュールのコードではありませんこのPython関数を他のサーバー側に移す必要があります。
何か問題が解決しない場合は教えてください。
