Somehow previously installed python packages had gone into the system folder. After specifying a different location in the houdini.env file and installing the houdini related packages there the issue was resolved.

Hello,
It's been a while now that I get the errors below when I launch Houdini. Today I uninstalled 3 older versions that I had on my windows machine and installed the latest version 21.0.729 but I still get the errors.
I would imagine a fresh install removes any previously installed packages, dependencies and I assume Houdini's Python environment shouldn't conflict with other python environments that I may have installed on my computer.
Do I need to also uninstall all sideFX apps (license server, launcher etc) for a clean install? Is there anything else I am missing?

Thank you

A module that was compiled using NumPy 1.x cannot be run in
NumPy 2.4.3 as it may crash. To support both 1.x and 2.x
versions of NumPy, modules must be compiled with NumPy 2.0.
Some module may need to rebuild instead e.g. with 'pybind11>=2.12'.

If you are a user of the module, the easiest solution will be to
downgrade to 'numpy<2' or try to upgrade the affected module.
We expect that some modules will need time to support NumPy 2.

I have made a custom Python Panel, which lives inside a folder structure and loaded using a package.json file and the $HOUDINI_PYTHON_PANEL_PATH variable and a .pypanel file in xml format.
I am trying to make a button on an HDA that open a floating window and loads my panel, but I haven't had any luck so far.

The command below opens a PythonPanel, but I can't figure out how to change the selection on the drop down menu.
panel = hou.ui.curDesktop().createFloatingPaneTab(hou.paneTabType.PythonPanel, size800, 600))

Any idea of how to do that, or if there are any example code out there?

thank you
Georgios
