No Qt binding were found.

Hi

I am using gaffer-1.5.8.0-windows on Win 11 It seems like the QT component is missing from the download in this version. I also have gaffer-1.2.3.0-windows and that version doesn't produce any error when launching it.

c:\gaffer-1.5.8.0-windows>bin\gaffer.cmd
Traceback (most recent call last):

Could you take a look at this please @ericmehl ?

Hi @kursad-k, sorry for the slow response. The first thing I'd try is simply re-downloading and unpacking the zip file again. We've had some people on Windows occasionally getting bad extractions from the archive that caused some things to be missing.

You should have a sub-directory of python/PySide2 in the Gaffer directory with a bunch of files and some more subdirectories in it. That's where the Qt.py is going to try and load Qt from.

If you that directory exists, try starting Gaffer with gaffer env python to launch a Python terminal in the Gaffer environment. If you do import PySide2 as module, what do you get? If that runs without errors, what is the result of import shiboken2? Those are the commands Qt.py runs to try and import Qt and might shed some more light on what's going wrong.

Hi, thanks for the reply. gaffer-1.5.9.0-windows works for me.
