python缺少位置参数_Python多重处理：TypeError：__new __()缺少1所需的位置参数：'path'...

我目前正在尝试使用带有多处理后端的joblib库在python 3.5中运行并行进程。但是，每次运行时都会出现此错误：

Process ForkServerPoolWorker-5:

Traceback (most recent call last):

File "/opt/anaconda3/lib/python3.5/multiprocessing/process.py", line 249, in _bootstrap

self.run()

File "/opt/anaconda3/lib/python3.5/multiprocessing/process.py", line 93, in run

self._target(*self._args, **self._kwargs)

File "/opt/anaconda3/lib/python3.5/multiprocessing/pool.py", line 108, in worker

return recv()

File "/opt/anaconda3/lib/python3.5/multiprocessing/connection.py", line 251, in recv

return ForkingPickler.loads(buf.getbuffer())

TypeError: __new__() missing 1 required positional argument: 'path'这里是我用来运行它的joblib代码：
