Question
App Platform multiprocessing (Python)

Asked by gerardsyd
I’ve managed to deploy my app onto the App platform but when it runs, it now gives me an errno 38 Function not implemented? Looking through the tracestack, this looks related to using multiprocessing pools in my app. Is this not supported by the App platform?

I need multiprocessing.
Thanks!
Any update support?
I wish someone in sales had told us you can’t do multi-process on App Platform. PRETTY DAMN LIMITING IF YOU ARE USING python. And paying top dollar for a worker.
I managed to solve it by ditching the multiprocessing in favor of gevent.
But in my case i was trying to install a Celery worker with prefork pools (which are multitreaded).
I switched from running:
to run:
Not sure if you can also switch to gevent (or greenlet) and if doing so will benefit you, as gevent isn’t meant for CPU intensive tasks, but is fine in my case because it need it mainly for making a lot of http requests
