Hey guys, I’m running the latest Maya 2018 on MacOS.
I can import PySide2 it’s libraries without any hassle. However, whenever I attempt to load a basic gui (like the code below), Maya freezes and crashes. Anyone else experienced this? Anyone know how to fix it? Cheers James Basic code (I took this from https://github.com/mad-guru/maya/blob/master/_UI_sample): import maya.cmds as cmds import maya.mel as mel import pymel.core as pm class className(): def __init__(self): self.varA = 1 self.varB = 2 self.varC = None def definitionA(self): self.varC=self.varA+self.varB def definitionB(self, userName): if self.varC==None: return print ('Hi '+ userName + ', thanks for visiting.') print ('varC is equal to '+str(self.varC)) # creates instance of this class cn = className() #################################### # GUI ############################## #################################### # srinikom.github.io/pyside-docs/ from PySide2 import QtGui from PySide2 import QtWidgets from functools import partial import maya.OpenMayaUI as mui import shiboken2 def getMayaWindow(): pointer = mui.MQtUtil.mainWindow() return shiboken2.wrapInstance(long(pointer), QtWidgets.QWidget) # def className_U1(): objectName = 'pyMyWin' # check for existing window if cmds.window("pyMyWin", exists=True): cmds.deleteUI("pyMyWin", wnd=True) # create a window parent = getMayaWindow() window = QtWidgets.QMainWindow(parent) window.setObjectName(objectName) # create font font = QtGui.QFont() font.setPointSize(12) font.setBold(True) # create a widget widget = QtWidgets.QWidget() window.setCentralWidget(widget) # create a layout layout = QtWidgets.QVBoxLayout(widget) # horizontal QtGui.QHBoxLayout() # create buttons # imagePath = cmds/internalVar(upd=True)+'icons/blue_field_background.png' # button.setStylesheet("background-image: url("+1magePath+"); border:solid black 1px;color.rgb(0,0,0)") # A+B button button = QtWidgets.QPushButton("A + B") layout.addWidget(button) button.setFont(font) button.setMinimumSize(200, 40) button.setMaximumSize(200, 40) button.setStyleSheet("background-color: rgb(128,128,128); color: rgb(0,0,0)") button.clicked.connect(partial(cn.definitionA)) #C button button = QtWidgets.QPushButton("Print C") layout.addWidget(button) button.setFont(font) button.setMinimumSize(200, 40) button.setMaximumSize(200, 40) button.setStyleSheet("background-color: rgb(128,128,128); color: rgb(0,0,0)") button.clicked.connect(partial(cn.definitionB,'Adnan')) # create close button closeButton = QtWidgets.QPushButton('Close') layout.addWidget(closeButton) closeButton.setFont(font) closeButton.clicked.connect(window.close) # show the window window.show() As I ran Maya from a terminal, I’ve managed to get the following info from it (this is from the moment of running Maya) objc[2591]: Class RunLoopModeTracker is implemented in both /Applications/Autodesk/maya2018/Maya.app/Contents/MacOS/libQt5Core.5.dylib (0x10a4eef38) and /Library/Python/2.7/site-packages/PySide2/Qt/lib/QtCore.framework/Versions/5/QtCore (0x12e41d010).
