Let me check, see what can be learned ...

Hmm let me check something

Not sure on the cause but if you do:

mp.set_start_method('fork', force=True)

There is no semaphore leakage

and one experiment takes 40 hours to run, so i let them run in parallel

And only the main one ?

in my case, we need to evaluate the result across many random seeds, so each task needs to log the result independently.

Can I send you a wheel to test ?

YEY

Let me check that for a sec

I think I found something relating to the issue on the subprocess not logging. Let me check if we can share something quickly

yes, that’s the error i got

How do I reproduce it ? (all the processes are on the same machine?)

when i run the code i send you the other day, logging is perfect, but at the end of the code there is a semaphore warning, not sure if it’s related

now it has log, but only the initial one

You can use this to reproduce
