Error loading shotgrid desktop

I was wondering if anyone has run in to an error while loading shotgrid desktop.

Exception: - Looks like you are trying to run an App that uses a QT based UI, however the python installation that the Desktop engine is currently using does not seem to contain a valid PySide or PyQt4 install. Either install PySide into your python environment or alternatively switch back to using the native Shotgun Desktop python installation, which includes full QT support.

it seems to not be able to find pyside but I checked it was in the shotgun install just looking for any suggestions on this.

According to the message you posted your pipeline configuration is pointed at a different python interpreter than the one that is installed with SG desktop.

Is that the intended workflow?
