I am writing files (at a really fast pace) to a specific directory. I would like to monitor the directory for new files and then spawn a process that runs an external script. Right now, I am getting a pickling error (even though I am using Pathos) of
Can't pickle <type 'Struct'>: it's not found as __builtin__.Struct
I need help fixing the pickling error which may cause me to have to rethink what I am doing, which is fine.
Here's what I have so far:

from datetime import datetime

pool = Pool(processes=cpu_count())

observer.schedule(event_handler, path=watchPath, recursive=True)
observer.start()

try:

observer.unschedule_all()
observer.stop()
db.close()
#observer.join()
