Bootstraping Houdini problems

[asch75]

Hi guys;

I’m tryng to bootstrap houdini on a Deadline job to be able to load sgtk nodes (instead of swaping them with regular nodes before submitting).

I’m getting this error:

2024-05-09 16:03:15: 0: PYTHON: ModuleNotFoundError: No module named ‘hou’

These are the relevant lines of my script:

mgr = sgtk.bootstrap.ToolkitManager(sg_user=user)

mgr.base_configuration = os.environ["SHOTGUN_CONFIG_URI"]

mgr.do_shotgun_config_lookup = True

mgr.plugin_id = "basic.houdini*"

sg_entity = mgr.get_entity_from_environment()

engine = mgr.bootstrap_engine("tk-houdini", entity=sg_entity)

If I use engine = mgr.bootstrap_engine(“tk-shell”, entity=sg_entity) all seems to work without errors.
I’ve tried to add the houdini phyton39libs on PYTHONPATH and sys.path without success.

Also, not sure if loading tk-houdini will be enough to be able to render the sgtk nodes without swapping them, or if I need to swap them anyway.

So… a lot of questions here. Thanks for any help!

The engine is trying to import hou, but that is not available. Seems like the engine must be initialized iniside houdini. So move your sgtk code to hrender_dl.py, assuming you are using the default plugin.

Thanks @mois.moshev ; I figured out hou library is not available but didn’t know exactly where to put it. I’m still learning… Thansk for the tip!

For a bit more background: the Houdini.py plugin is run by Deadline. It starts hython in a subprocess, passing it the hrender_dl.py script to execute. In the Houdini Job reports, look for the line “Full Command”, and you’ll see what I mean.
