ModuleNotFoundError: homni.ui

Dear Omni team,

After installing Houdini 20 connector, when trying to connect, I’m having following error that I can not solve:

ModuleNotFoundError: No module named ‘homni.ui’

Could you please help me?

Many thanks

Hello @pedrotamarit
We currently support Houdini 20 with Python 3.10 build.
To find out which python version you are running with - Please go to

Top menu barHelpAbout Houdinicheck “Show Details” and look for “Python Version”

And if you are running on Ubuntu - please also make sure you are running Houdini 20 with gcc 9.3 build - You can find it on SideFx’s download page here. Please make sure you are not downloading the Python 3.9 builds.

If everything above looks correctly - Please check your $home/houdini20.0/packages. There should be a file called omniverse.json
Open the file in any text editor and find this line

“HOMNI” : “C:/Users/xxxx/AppData/Local/ov/pkg/prod-houdini-connector-200.0.1/houdini20.0”

Please make sure the directory exists and the ui module lives in

C:/Users/xxxx/AppData/Local/ov/pkg/prod-houdini-connector-200.0.1/houdini20.0/houdini/python3.10libs/homni/ui

If no files exist in the directory, please try to uninstall and reinstall the connector. If everything looks correct, could you please copy and paste your system and Houdini info here?

Many thanks for the quick answer.

My python build is 3.9

How can I easily change it to 3.1?

Hello @pedrotamarit
you should be able to download it from SideFx’s site here

Solved !

Many thanks for your great support
