When launching Houdini, now getting python related errors from a python library that is used by Nuke. Simple question, what do I need to setup environment-wise to have Houdini only deal with python that is in $HFS?

Also, seems latest versions are installing python26 AND python27 into the $HFS directory. Is that so or am I imagining this? TIA

Further to this, I read there is an environment variable called HOUDINI_USE_HFS_PYTHON that when set to 1 forces Houdini to read the Python package that comes with Houdini. Does this work? I tried it with no luck … set in Windows Control Panel and also tried houdini.env file.

Please note that I'm using Windows and simply double clicking on the Houdini icon on the desktop.

help

Hello,

HOUDINI_USE_HFS_PYTHON only works on Linux and MacOS.

On Windows, Houdini always runs against the Python library/distro that ships in $HFS. And although there may be a python26 (legacy) folder in $HFS, Houdini 16.0 only supports and works with Python 2.7.

It's more likely that you are running into a problem where Houdini is trying import and run a Python module that is being picked up from the Nuke installation. Perhaps check if you have any PYTHON* variables (i.e. PYTHONPATH) set in your environment and temporarily unset them to see if that helps.

Cheers,
Rob
