need multiprocessing help

[mtsol]

"Use Python's multiprocessing module. For better or for worse, Python took the route of preferring multiprocessing over multithreading. There is a powerful multiprocessing module you can use to spawn separate processes. These spawned processes will appear as children of the original Java process, but they will actually be pure Python. Spawning Python subprocesses complicates things and requires pure Python code to be run in the separate process and sending objects (usually pickled/cpickled) back to the Jep interpreter running inside Java."

there are your words from https://github.com/ninia/jep/wiki/Jep-and-the-GIL

can you share some more information about this or any example?

I removed that snippet from the wiki. multiprocessing has been used in the past with jep but no one has looked closely at this since Python 2.7 and I don't think it works very well with Python 3.x. We don't have the resources to investigate multiprocessing further at this time. If anyone else has succcessfully used multiprocessing with jep and would be willing to document it then we could update the wiki but for now I don't want to advertise a feature that we aren't currently supporting/testing.

I just removed the bit you pasted from our wiki, because it is outdated and not well supported, you can see the change at https://github.com/ninia/jep/wiki/Jep-and-the-GIL/_compare/33dbe7da561a6c34653f02478f3230f1b3431f7e...ca48e96cc80b5bc4cd74bcbb2b751111a549a48e
