I am learning how to load a UI with pyside_dynamic. The problem is the tutorials where written for earlier version of Maya. (I am using maya2017)

Here is the code I have been instructed to write. The error is this:    "No module named PySide.QtCore"  What should I write instead ?
I read a blog that said "Maya 2017 was released today and with it comes a big change; PySide (and PyQt4) no longer works with Maya."

# Error: No module named PySide.QtCore
# Traceback (most recent call last):
#   File "<maya console>", line 1, in <module>
#   File "E:\ProfessionalDevelopment\python\Introduction to Python Scripting in Maya\cgcircuitPython\wk6\geomGenerator_pysideDynamic.py", line 6, in <module>
#     import pyside_dynamic2
#   File "C:/Users/justin/Documents/maya/2017/scripts\pyside_dynamic2.py", line 42, in <module>
#     from PySide.QtCore import Slot, QMetaObject
# ImportError: No module named PySide.QtCore #


import os
from PySide2 import QtWidgets, QtCore, QtUiTools, QtGui
from shiboken2 import wrapInstance

import pyside_dynamic2

import maya.cmds as mc
import maya.OpenMayaUI as omui

def getMayaWindow():
    ''' pointer to the maya main window '''
    ptr = omui.MQtUtil.mainWindow()
    if ptr:
        return wrapInstance(long(ptr), QtWidgets.QMainWindow)

def run():
    ''' builds our UI '''
    global win
    win = GeometryGenerator(parent=getMayaWindow())
    win.show()

uiFilePath = os.path.join( os.path.dirname(__file__) , 'geomGenerator_v001.ui')
   
class GeometryGenerator(QtWidgets.QDialog):
   
    def __init__(self,parent=None):
        super(GeometryGenerator,self).__init__(parent)
        self.ui = pyside_dynamic2.loadUi(uiFilePath,self)

Do you see the difference between how you are importing PySide (1.x) in your pyside_dynamic2 module, and PySide2 (2.x) in your geomGenerator_pysideDynamic.py module?

Looks like in you are importing the wrong module, for the version of Maya you are using.

you need to import PySide2, like you do in your code snippet. In one of your modules you are importing PySide.

a good rule of thumb is to implement a try, where you try import pyside2, and then if that fails import pyside1

try:
    
    from PySide2.QtGui import *
    from PySide2.QtWidgets import *
    from PySide2 import __version__
    from shiboken2 import wrapInstance
except ImportError:
    
    from PySide.QtCore import *
    from PySide.QtGui import *
    from PySide import __version__
    from shiboken import wrapInstance

I am getting confused. So I need to back up a bit. It all relates to being able to launch a pyside_dynamic ui in maya.

I have been asked to drop this pyside_dynamic2.py file (see attached) into my maya scripts dir. When I try to import it I get this error. 

import pyside_dynamic2
# Error: No module named PySide.QtCore
# Traceback (most recent call last):
#   File "<maya console>", line 1, in <module>
#   File "C:/Users/justin/Documents/maya/2017/scripts\pyside_dynamic2.py", line 42, in <module>
#     from PySide.QtCore import Slot, QMetaObject
# ImportError: No module named PySide.QtCore # 

Do I need to edit this script or is it redundant now with maya2017 ? 
pyside_dynamic2.py

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.

Thanks Simon,
 I switched out all PySide to read PySide2. I also switch QtGui to QtWidgets

As a note. Not all qtgui was moved to qtwidgets. Some things still live in qtgui. Not just a search and replace

This page shows me all the modules for  pySide https://deptinfo-ensip.univ-poitiers.fr/ENS/pyside-docs/index.html  

I have found this page for pySide2 https://wiki.qt.io/PySide2 But I am unable to see a list of pySide2's available modules?

The first one is generated and hosted by some domain. I didn't find anyone hosting the built pyside2 docs . I'm not sure why the pyside project doesn't host their own active build of the 2.0 branch.

Pyside is now maintained by the qt company, so the builds are now all on their qt-project.org code site.

Are you saying the docs for PySide2 is on qt-project.org? Where, exactly? :S

Ah, so you were. Sorry about that, I'm reading it from my mailbox as one single thread.

This comment was exactly referring to the build of the docs. Where do they host the build of the docs on their site?

ok, I thought you were talking about the software itself.
