I took a look at the file. It was build using pyside 1, and Maya 2017 uses pyside 2. So in order to get this to work in maya, you will have to update the file, and migrate all the pyside 1 modules and calls to pyside 2.
It can be a good task, as you learn about the changes in the API. Here is a link to Maya pyside. http://help.autodesk.com/view/MAYAUL/2017/ENU/?guid=__files_GUID_3F96AF53_A47E_4351_A86A_396E7BFD6665_htm -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
