python-multithreading

I have a python multi-threaded application. I want to run an asyncio loop in a thread and post calbacks and coroutines to it from another thread. Should be easy but I cannot get my head around the asyncio stuff. I came up to the following solution which does half of what I want, feel free to comment on anything: import asyncio from threading import Thread class B(Thread): def __init__(self): Thread.__init__(self) self.loop = None def run(self): self.loop = asyncio.new_event_loop() asyncio.set_event_loop(self.loop) #why do I need that?? self.loop.run_forever() def stop(self): self.loop.call

Some functions should run asynchronously on the web server. Sending emails or data post-processing are typical use cases. What is the best (or most pythonic) way write a decorator function to run a function asynchronously? My setup is a common one: Python, Django, Gunicorn or Waitress, AWS EC2 standard Linux For example, here's a start: from threading import Thread def postpone(function): def decorator(*args, **kwargs): t = Thread(target = function, args=args, kwargs=kwargs) t.daemon = True t.start() return decorator desired usage: @postpone def foo(): pass #do stuff I've continued using this

What is the reason of such issue in joblib? 'Multiprocessing backed parallel loops cannot be nested below threads, setting n_jobs=1' What should I do to avoid such issue? Actually I need to implement XMLRPC server which run heavy computation in background thread and report current progress through polling from UI client. It uses scikit-learn which are based on joblib. P.S.: I've simply changed name of the thread to "MainThread" to avoid such warning and everything looks working good (run in parallel as expected without issues). What might be a problem in future for such workaround? This seems

I am new to multithreading in python and trying to learn multithreading using threading module. I have made a very simple program of multi threading and i am having trouble understanding the threading.Thread.join method. Here is the source code of the program I have made import threading val = 0 def increment(): global val print "Inside increment" for x in range(100): val += 1 print "val is now {} ".format(val) thread1 = threading.Thread(target=increment, args=()) thread2 = threading.Thread(target=increment, args=()) thread1.start() #thread1.join() thread2.start() #thread2.join() What
