PySide6.QtGraphs.QSurfaceDataProxy.resetArrayNp called with wrong argument types:

G4IXT

I am attempting to migrate a surface graph in a python App from Pyqtgraph/PyQt5 to pyside6/QtGraphs.

pyside 6.9.3
python 3.14

This simple test code (qsurfacedataproxy and qsurface3dseries imported from pyside6 QtGraphs and defined):

    arry = np.array([[1.0, 2.0, 3.0],[4.0, 5.0, 6.0],[7.0, 8.0, 9.0]])
    self._dataProxy.resetArrayNp(0.0, 1.0, 0.0, 1.0, arry)

I get the errors below. I cannot see what I am doing wrong, is this a bug in the new QtGraphs module?

FIXME qt_isinstance([[1. 2. 3.]
[4. 5. 6.]
[7. 8. 9.]], collections.abc.Sequence[typing.Any]): isinstance() argument 2 cannot be a parameterized generic"

and

TypeError: 'PySide6.QtGraphs.QSurfaceDataProxy.resetArrayNp' called with wrong argument types:
PySide6.QtGraphs.QSurfaceDataProxy.resetArrayNp(float, float, float, float, ndarray)
Supported signatures:
PySide6.QtGraphs.QSurfaceDataProxy.resetArrayNp(x: float, deltaX: float, z: float, deltaZ: float, data: collections.abc.Sequence[typing.Any], /)

I have tried everything I can think of to make it work and simplified my previous code to the test example ablove.

Hi and welcome to devnet,

Can you provide a minimal runnable script that shows this issue ?
Did you also try with a more recent version of PySide6 ?

G4IXT

No, I haven't tried a more recent version of PySide6 as it's not available in conda-forge that I used for my env.

The example works fine using a standard PySide6 package (pip install PySide6-Addons). This probably means that Conda builds PySide6 without numpy support.

@friedemannkleint thank you, I will investigate

I created another environment using venv instead, and the test code works. I didn't realise that there could be problems like that using conda environments, I thought that I was making a "wholesome" system to work in. Every day is a school day, even at 65 years old. Thanks again for the help.

@G4IXT Hi,

As an alternative you can very well install PySide6 in your conda environment using pip.

That way you can use conda to manage your environments.
