python 的Process 多进程的异常问题？

Question

`
E:\APP\python3.7.4_32\python.exe P:/yys_project/yys/dxmain.py
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "E:\APP\python3.7.4_32\lib\multiprocessing\spawn.py", line 105, in spawn_main

exitcode = _main(fd)

File "E:\APP\python3.7.4_32\lib\multiprocessing\spawn.py", line 115, in _main

self = reduction.pickle.load(from_parent)

EOFError: Ran out of input
`

请教一下,一启动该进程就异常,有什么解决方案吗?
