Try spinning a 1.6.0 server to see if it will work there. BTW what python version are you using?

yes, it was left by mistake (it calls)
from clearml import Taskdoesnt change the behavior

thanks! let me know how it goes! :)

The sample script you posted runs fine on server 1.6.0. I did however comment out from machine_learning.clearml_client import Task and used from clearml import Task

Can you please try with the regular import?

try this one (even when running without debug)
` import multiprocessing
import time

from clearml import Task

def init_clearml_task(patch_set_name, model_name, is_ensemble):
task_name = f'{patch_set_name} {model_name}'
task = Task.init(
project_name=f"bla CV",
task_name=task_name,
tags=[model_name, patch_set_name],
reuse_last_task_id=False
)
task.connect({"bla": "bla"}, 'IbexConfig')
return task

def execute_1():
print("proc1")
task = init_clearml_task("alg1", "train1_debug_cml", is_ensemble=False)
time.sleep(5)
task.close()
print("done_proc2")

def execute_2():
print("proc2")
task = init_clearml_task("alg2", "train2_debug_cml", is_ensemble=False)
time.sleep(5)
task.close()
print("done_proc2")

proc = multiprocessing.Process(target=execute_1)
proc.start()
proc.join(35000)
time.sleep(5)
print("father_script_done_proc1")
task = init_clearml_task('summary', 'alg1_debug_cml', is_ensemble=False)
time.sleep(5)
task.close()
time.sleep(5)
proc2 = multiprocessing.Process(target=execute_2)

proc2.start()
time.sleep(5)
proc2.join(35000)
time.sleep(5)
print("done???????????????") `

from some reason it happend in the example I gave when running in debug only, maybe matter of timing, but it happend in my "real" script also not in debugging

I will update to 1.6 after the weekend and check

python 3.6.9

I updated the versions to clearml 1.6.2 Server 1.5.0, it still happening , when calling
init_clearml_task('summary', 'alg1_debug_cml', is_ensemble=False)clearml doesnt create a new task, but now the process doesn't crush

do you say when running on 1.6.0 you see 3 tasks? (where I see 2)

I'll try and see if it reproduces on my side, thanks! 🙂

clearml version 1.0.5, Server 1.1.0

I cant because we have some experiments running (I didnt update before, just used another newer server)

ThankfulHedgehong21 , server 1.6.0 is available. Can you try with it as well?

Hi ThankfulHedgehong21 ,

What versions of ClearML & ClearML-Agent are you using?
Also, can you provide a small code snippet to play with?
