从另一个Python脚本中并行启动IPython

假设我有两个Python文件

test.py

from ipyparallel import Client

def hi(a):
    return b + (a * 2)

def run():
    b = 3

    client = Client()
    view = client[:]

    view.push({'b':b})
    results = view.map(hi, [0,1,2,3,4])
    for r in results:
        print(r)

from test import run

if __name__ == '__main__':
    run()

和driver.py

from ipyparallel import Client

def hi(a):
    return b + (a * 2)

def run():
    b = 3

    client = Client()
    view = client[:]

    view.push({'b':b})
    results = view.map(hi, [0,1,2,3,4])
    for r in results:
        print(r)

from test import run

if __name__ == '__main__':
    run()

我收到错误[0:apply]：name错误：未定义名称“b”

---

如果我从test.py中调用run（），这段代码就可以工作，但是，我不想这样做。我想从driver.py中调用run（）。有关如何解决此问题的任何想法？

在

test.py

文件导入

interactive

，然后在

map

函数中使用

interactive（hi）

而不是

hi

：

from ipyparallel import Client
from ipyparallel.util import interactive

def hi(a):
    global b
    return b + (a * 2)

def run():
    b = 3
    client = Client()
    view = client[:]
    view.push({'b':b})
    results = view.map(interactive(hi), [0,1,2,3,4])
    for r in results:
        print(r)

if __name__ == '__main__':
    run()
