Qt binding related ImportError encountered when using fossil script commands in 2025.3.1

[BenFreedman]

import pdil.tool.fossil.main
pdil.alt.call('Rig Tool')()
# Error: ImportError: No Qt binding were found.
import pdil.tool.fossil.main
pdil.alt.call('Rig Tool')()
# Error: ImportError: file C:\Users/**<user>**/Documents/maya/scripts\pdil\vendor\Qt.py line 1719: No Qt binding were found.

Note:
Latest pip and pymel installed as of 6/20/2025

Looks like support for QT6 was added to Qt.py vendor file: (with QT6 transition guide)

• https://github.com/mottosso/Qt.py
• https://github.com/mottosso/Qt.py?tab=readme-ov-file#qt-6-transition-guide

Looks like Maya swapped from PySide2 to PySide6 in 2025:

• https://doc.qt.io/qtforpython-6/faq/porting_from2.html

---

Attempted local fix by:

• Overwrote Qt.py with newer version

• Replaced PySide2 mentions with PySide6 as respecitvely (probably was unnecessary given Qt.py)

• Eventually ran into this Error and wasn't sure how to proceed:

pdil.alt.call('Rig Tool')()
# Error: AttributeError: module 'inspect' has no attribute 'getargspec'

Looks like it arises from:
C:\Users<user>\Documents\maya\scripts\pdil\tool\fossil_lib\tpose\adjusters.py (line 65)

Quick search yielded:
https://docs.python.org/3/library/inspect.html#inspect.getargspec:~:text=inspect.getfullargspec(func)

Changed in version 3.6: This method was previously documented as deprecated in favour of signature() in Python 3.5, but that decision has been reversed in order to restore a clearly supported standard interface for single-source Python 2/3 code migrating away from the legacy getargspec() API.
