Bootstrapping and launching hython

Hi

I’ve a command line setup successfully working, This is what I followed

All have been working pretty well. Today I added “hython” (command line Houdini) as new software. It closes immediately after the successful launch. Any help/tip?

here is the snippet of my code, if you are interested.

engine = mgr.bootstrap_engine(“tk-shell”, entity=sg_show)
engine.execute_command(“hython”, )
