I just try it and see what works ;).
The general idea is that if it is module-level it can be pickled and
if it is defined inside of something else it cannot. It depe
Thanks for the post.
I actually don't know exactly what can and can't be pickles..
not what partialing a function means..
Maybe can you link me to some resources?
I still can't understand all the details in your code :)

"new" is deprecated from 2.6+; use types.MethodType instead of
new.instancemethod.

No I am using Ubuntu (12.04, 64 bit).. maybe things changed from 3.2 to 3.3?

Yeah actually that wouldn't work even in Python 3, since value attribute used
by fun has not been set.
It was my mistake in th

I have tried a lot of variations, instantiating the object, creating lambda
functions that use the unbound version of fun (A.fun.__func__) etc etc..
I have pl

Do you ever instantiate any
Hi guys,
I would like to apply the Pool.map method to a member of a class.
Here is a small example that shows what I would like to do:
from multiprocessing import Pool

def fun(self,x):
return self.value**x
l = range(10)
15 matches
