I'm running 20.0.751 on Rocky 9 with python 3.10.6 installed and I'm struggling to get hou integrated into my python scripts. I dont want to use hython because its an existing python app I am running, I want to integrate houdini functions into this existing script.


$ source houdini_setup
The Houdini 20.0.751 environment has been initialized.

$ python
Python 3.10.6 (main, Mar 4 2024, 09:24:28) on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import hou
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'hou'



$ hython
Python 3.10.10 (main, Sep 7 2023, 14:12:34) on linux
Houdini 20.0.751 hou module imported.
>>>




$ export PYTHONPATH=/opt/hfs20.0.751/houdini/python3.10libs/
$ python

import _hou
ImportError: libpython3.10.so.1.0: cannot open shared object file: No such file or directory
>>>

any ideas on why I cant import hou?

LD_LIBRARY_PATH is not set to anything in my environment

just to update. installing python 3.10.10 to match houdini is giving the same error

Yes, you can do that

couldnt get it working with python 3.10

installed the py3.9 version of houdini and that works if I also switch to python3.9 in my alternatives
