  Multiprocessing with pykx hanging on trying to load db from disk

  Posted by milk on January 2, 2025 at 8:00 pm

  Hi,

  I’m starting up a new process using multiprocess in python, where I feed in multithreading.queue into a custom function

   p = multithreading.Process(target=function, args=(queue,))

   p.start()

  However, in my function in the new process, I try to load a db using

  pykx.DB(path=”/home/user/test”)

  and this query hangs.  I can run other simple queries, but it seems the call to system loading a path doesn’t work.

  Is there something preventing pykx from using system functions in a separate process?  If it matters i’m using pykx 2.5.2 (with beta features enabled).  If I try this in the main process it works fine.

  What OS are you using?

  PyKX does not support multiprocessing on Windows.

    linux (centos)

    The link you provided is about multithreading?  Not multiprocessing?
