Pipe () command on windows

I'm trying to make a simple communication between processes, but the child f_filho is not receiving the message sent by the parent.

How to solve?

# -*- coding: cp1252 -*-
from multiprocessing import Process,Pipe
import numpy as np

def f_filho(pipe):
    frase=pipe.recv()
    print frase

if __name__ == '__main__':
    pipe_pai,pipe_filho=Pipe()
    print('começando o programa')
    p=Process(target=f_filho , args=(pipe_filho,))
    p.start()
    pipe_pai.send(['ola meu filho'])  #inica comunicação pelo pipe para o filho
    pipe_pai.close()
    p.join()
    print('fiiim')
