Python multiprocessing Process crashes silently

Question

I\'m using Python 2.7.3. I have parallelised some code using subclassed multiprocessing.Process objects. If there are no errors in the code in my subclassed Process

Answer 1

I suggest such workaround for showing process's exceptions

from multiprocessing import Process
import traceback


run_old = Process.run

def run_new(*args, **kwargs):
    try:
        run_old(*args, **kwargs)
    except (KeyboardInterrupt, SystemExit):
        raise
    except:
        traceback.print_exc(file=sys.stdout)

Process.run = run_new
