Maya Python - “您需要基于 shiboken 的类型”错误

Question

Many Python based tools in Maya are now returning an error that is new to me. " You need a shiboken-based type. # "

Very fresh to Python, so I don't really know what the issue is. After looking around a bit a figured out it's maybe a conflict of definitions

The " QtGui " module is probably being imported more than one times, creating said conflict. Not entirely sure that's the main cause, but it's the main suspect for now.

Now to be honest, I have just now started noticing that some of Maya's Python tools are not functioning because of this (like the "Type" creation tool), meaning that I have installed/uninstalled several python packages using pip before coming across the issue. I have no clue which package could be causing the conflict.

Are there any usual suspects that can cause this conflict? I tried uninstalling some of the more recent packages but with no luck.

I also wouldn't want to damage anything else by individually removing packages until I find it.

These are the packages installed:

As an example for when this error occurs, I'm also including this script from PyFlow:

import ptvsd
from maya import OpenMayaUI as omui
from shiboken2 import wrapInstance
from PyFlow.App import PyFlow
from PySide2.QtWidgets import QWidget

try:
    long  # Python 2
except NameError:
    long = int  # Python 3path

ptvsd.enable_attach(address=('0.0.0.0', 3000), redirect_output=True)

mayaMainWindowPtr = omui.MQtUtil.mainWindow()
mayaMainWindow = wrapInstance(long(mayaMainWindowPtr), QWidget)

if PyFlow.appInstance is None:
    instance = PyFlow.instance(mayaMainWindow, "maya")
    instance.show()

" PyFlow " is a promising little tool for visual scripting, which is great for novices like myself. The issues didn't start when I first ran it, but it helped me notice the error that many other python-based tools in Maya were giving now as well.

If I attempt to run this for example:

" # Error: TypeError: file line 15: You need a shiboken-based type. # "

Answer 1

have you an example of script that import QT ui. Which version of maya are you using also ?

are all your imports look like this :

from PySide2 import QtWidgets, QtGui, QtCore
import shiboken2

have you maybe mix PyQt and PySide with some " import sip2 "

---EDIT---

from maya import OpenMayaUI as omui
from shiboken2 import wrapInstance
from PyFlow.App import PyFlow
import PySide2.QtWidgets as QtWidgets

mayaMainWindowPtr = omui.MQtUtil.mainWindow()
mayaMainWindow = wrapInstance(long(mayaMainWindowPtr), QtWidgets.QWidget)

if PyFlow.appInstance is None:
    instance = PyFlow().instance(mayaMainWindow, 'maya')
    instance.show()
