error with pyside2 backend on macOS arm64 #2406

psobolewskiPhD · 2022-10-16T18:55:30Z

Originally I noted this with napari, see: napari/napari#5231

But it seems to be a vispy issue, because if you install:
mamba create --name test-env3 python=3.9 pyside2 vispy
then examples fail, for example https://vispy.org/gallery/scene/turntable_box.html#sphx-glr-gallery-scene-turntable-box-py
Error:

Do we know if this is specific to MacOS? Specific to ARM64 macs? Specific to the version of Qt that PySide 2 is using?

djhoese · 2022-10-17T14:02:56Z

As far as I can tell that method should exist in PySide2:

https://doc.qt.io/qtforpython-5/PySide2/QtWidgets/QOpenGLWidget.html?highlight=qopenglwidget#PySide2.QtWidgets.PySide2.QtWidgets.QOpenGLWidget.defaultFramebufferObject

Do we know if this is specific to MacOS? Specific to ARM64 macs? Specific to the version of Qt that PySide 2 is using?

Sorry I don't have access to any other machine at the moment. It could be all of those.
It could also be specific to the pyside2 conda-forge package—I can't install from pip because lack of wheel.
But: napari runs CI tests with pyside2 on ubuntu (PySide2==5.15.2.1) and windows (PySide2==5.15.2.1) and they are fine, so probably mac related? though it could still be version related. And tox uses pip, so it could be conda-forge related...
I'll keep poking around.

Edit: on the napari side, Andy tested with macOS 12.6 but x86 and no issues:
napari/napari#5231 (comment)
So it's related to arm64 pyside2.

psobolewskiPhD · 2022-10-18T09:42:09Z

I ran the pyside2 example: https://github.com/pyside/pyside2-setup/blob/5.15/examples/widgets/widgets/tetrix.py
and it works fine in the conda-forge pyside2 env

So maybe it's some interaction between arm64 pyside2 and vispy?

Edit: OpenGL example also works, after installing pyopengl
https://github.com/pyside/pyside2-setup/blob/5.15/examples/opengl/hellogl.py

djhoese · 2022-10-18T12:03:55Z

I could be missing something but I don't see pyside2 wheels for non-intel macs here:

https://pypi.org/project/PySide2/#files

I'm surprised it installed at all.

pyside2 is built for arm64 macOS on conda-forge:

I hit the issue when napari installed from conda-forge pulled pyside2 backend instead of pyqt5.

djhoese · 2022-10-18T15:12:31Z

Ah sorry, I thought you were making a point between PyPI pyside2 and conda-forge pyside2. I misread that you were running a pysides2-only (no vispy) example.

djhoese · 2022-10-18T15:14:08Z

Looks like that pyside2 opengl example is using the old GL API by using the QGLWidget instead of the newer (Qt 5+) API with QOpenGLWidget like VisPy does:

vispy/vispy/app/backends/_qt.py

Line 130 in 8bf4f9e

from PySide2.QtWidgets import QOpenGLWidget as QGLWidget

psobolewskiPhD · 2022-10-18T17:44:47Z

@Czaki is helping with some testing in the napari issue thread:

@psobolewskiPhD could you run this code (from script) and paste output

import qtpy
from vispy import app

# set vispy application to the appropriate qt backend
app.use_app(qtpy.API_NAME)

from vispy.app.backends import _qt as vqt

print("qt new",  vqt.QT5_NEW_API)
print("pyqt6",  vqt.PYQT6_API)
print("pyside6",  vqt.PYSIDE6_API)
print("egl", vqt.USE_EGL)
print("attr",  vqt.QGLWidget, hasattr(vqt.QGLWidget, "defaultFramebufferObject"))

Here's what I get with pyside2
and the env with "napari=*=*pyside2*"

╰─ python test_pyside2.py                                         (test-env2) ─╯
qt new True
pyqt6 False
pyside6 False
egl False
attr <class 'PySide2.QtWidgets.QOpenGLWidget'> False

vs Here's my regular pyqt env:

╰─ python test_pyside2.py                                        (napari-dev) ─╯
qt new True
pyqt6 False
pyside6 False
egl False
attr <class 'PyQt5.QtWidgets.QOpenGLWidget'> True

Czaki · 2022-10-18T19:01:34Z

This is pyside2 (probably feedstock) problem.

Here Linux pyside2 output.

$ python py_vispy.py 
qt new True
pyqt6 False
pyside6 False
egl False
attr <class 'PySide2.QtWidgets.QOpenGLWidget'> True

psobolewskiPhD · 2022-10-18T19:13:51Z

What version of pyside2 and installed from where?
Part of the problem testing is that pip pyside is out of date.

Czaki · 2022-10-18T20:00:06Z

here output from conda env:

$ python py_vispy.py 
qt new True
pyqt6 False
pyside6 False
egl False

Ok, so generally the same. 🤷‍♂️

Czaki · 2022-10-18T20:19:43Z

Also it is mentioned in pyside2 docs:

https://doc.qt.io/qtforpython-5/PySide2/QtWidgets/QOpenGLWidget.html#PySide2.QtWidgets.PySide2.QtWidgets.QOpenGLWidget.defaultFramebufferObject

so it looks like a bug in the build process.

psobolewskiPhD · 2022-10-29T12:45:37Z

FYI: I made a python 3.10 env, which has a different build number for pyside2 and get the same error.
Edit:
Also I've made an emulated (Rosetta2) x86 env, and pyside2 from conda-forge does work with vispy. I think I will open an issue on conda-forge feedstock.

psobolewskiPhD · 2022-11-08T13:18:59Z

Update: it's not a conda-forge specific issue.
pyside2 arm64 from homebrew also has the same problem, see:
napari/packaging#35 (comment)

psobolewskiPhD · 2023-01-11T09:07:51Z

Update2: it's been reported up-stream by Julien Schueller
https://bugreports.qt.io/browse/PYSIDE-2187

psobolewskiPhD · 2023-01-12T12:08:31Z

conda-forge/pyside2-feedstock#175
has been merged and I can confirm the issue is solved!
hasattr(QOpenGLWidget, "defaultFramebufferObject")
reports True on macOS 13.1 arm64 for pyside2 build live on conda-forge.
Everything works as far as I can tell.
