Parallel execution of Python scripts

[BiralKevin]

Hi 
Does someone know if its possible to execute two Python Action steps in parallel?
I already tried so many things and nothing really worked.

• Tried using seperate sub-sequences started as New Thread.
• Set Python Setting Interpreter to use "Per Thread".
• Used on each Action step different intepreter for one step python 3.13 and for the other step 3.14.
  According to this doc entry Python Interpreter Sessions - NI it's recommended to use seperate interpretor but even this did not work.

It's always the same result, when I have a while Loop in one Python script this will blocking.
Does anyone have experience how to execute Python steps in parallel?

Thanks

Don't have much Python experience.... though still trying to be helpful asking some stupid questions 🙂

1.) It's two different script, right?

2.) What do these scripts do?

• Is this caused by some implicit ressource locking? 
• Have you tried with a simple script (no hardware or such)

Many thanks for your fast reply.
I didn't interact with any hardware, they were just two seperate simple Python scripts with prints and loops to understand the issue.
I tried now to make an example test sequence with example python scripts which I could share here in the forum and now it is working for some reason. I have no clue why it didn't yesterday.
But for now my issue seems to be solved.
I come back as soon I would have the same issue again
