There is no debugging message in multiprocess setting?

1

Today, i tried to realize a3c using pytorch.multiproecss module, and i found that even if there are some bug in the target code (Process(target=target,...)) , there is nothing printed in the console. Does pytorch just ignore the error message in the multiprocess setting? if it is true, can anyone add some debugging message in the multiprocessing setting.
Thanks.

ubuntu 16.04
pytorch 0.2.0_1

Did you flush the output using sys.stdout.flush()?

PyTorch multiprocessing is a wrapper around the Python multiprocessing module. So what you are seeing is likely related to the native module.
