我正在做一个项目其中运用了神经棒，我想用运用多进程将神经棒与另外一个程序进行通讯
，但是我发现用多进程的时候，他总是显示无法开启神经棒不知道是什么原因。有没有大神
能帮忙解决下。
主程序如下：
** from move import Move
from hh import Detect
from capture1 import Capture
from multiprocessing import Process, Queue
import time
import cv2
q1 = Queue()
q2 = Queue()
def CAP_DETC(q1,q2):
cap = Capture()
cap_detc = Detect()
while True:
cap.save_img()
img = cv2.imread('images/1.jpg')
time.sleep(0.1)
if q2.get():
p = cap_detc.preprocess_image(img)
m = cap_detc.predict(p)
n = cap_detc.judge(m)
q1.put(n)
def MOVE(q1,q2):
move = Move()
q2.put(1)
while True:
if q1.get() == 1:
move.turn_right()
elif q1.get() == 2:
move.turn_left()
elif q1.get() == 0:
move.go_forward()
elif q1.get() == 3:
move.stop()
move.turn_left()
else :
print 'Something is wrong!'
move.stop()
p1 = Process(target=CAP_DETC,args=(q1,q2))
p2 = Process(target=MOVE,args=(q1,q2))
p1.start()
p2.start()
p1.join()
p2.join()**
在Terminal显示的错误:

如果我采用多线程的方式的话，它是可以进行的。一开启进程就不可以了希望有大神帮忙解决下。
