请教报错信息～ #5

hi, 我这边运行时一直报错，信息如下：
Traceback (most recent call last):
File "monkeyTest.py", line 154, in
runnerPool()
File "monkeyTest.py", line 77, in runnerPool
pool.map(start, devices_Pool)
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/pool.py", line 251, in map
return self.map_async(func, iterable, chunksize).get()
File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/multiprocessing/pool.py", line 567, in get
raise self._value
OSError: [Errno 2] No such file or directory

麻烦您知道我该如何解决吗，非常感谢～
