Hi @<1523701323046850560:profile|OutrageousSheep60>
What do you mean by "in clearml server" ? I do not see any reason a subprocess call from a Task will be an issue. What am I missing ?

from the example -
since the `mp_hander`` runs

cmd = [sys.executable, sys.argv[0],
               '--counter', str(counter - 1),
               '--num_workers', str(args.num_workers),
               '--use-subprocess' if args.subprocess else '--no-subprocess']
p = subprocess.Popen(cmd, cwd=os.getcwd())

can I run another subprocess in the mp_worker ?

Can't see any reason not to 🙂

@<1523701205467926528:profile|AgitatedDove14> -
I'm getting the following error when running the following code within the mp_worker

command = ["ffmpeg","-i",f"{url}","-vcodec","libx264", "output.mp4"]
subprocess.run(command, stderr=subprocess.STDOUT)

TypeError: fork_exec() takes exactly 21 arguments (17 given)

Any suggestions?

Wait, why aren't you just calling Popen? (or os.system), I'm not sure how it relates to the torch multiprocess example. What am I missing ?
