Hi @AMAN-9608

Could you share the code, which would help to see how the subprocess is being used in the confinement of a Streamlit app.

Hi!
I got the code working, not sure what changed, but if someone in the future needs it, I’m using:
subprocess.run([“python”,“script.py”)
It seems earlier I was trying to run another streamlit run command.
