My app crashes on the laptop and not on the desktop

SGaist

Hi,

Which version of Qt are you using ?
Which OS ?
Which graphics driver ?

Hello, I'm using PyQt 5.15.2 and PyQt3D 5.15.2 on Windows 10 (Both machines).
I have an amd card on the desktop where I don't have this problem and an nvidia gtx1050ti on the laptop where it happens.

Nvidia driver version: 457.51

SGaist

How did you install these packages ?

You might also want to check if your drivers are the latest and if so, downgrade to test if they introduced a bug.

Gibser

I installed the packages via pip. However, creating a standalone executable with cxfreeze is also the same. I also confirm that the same happens on my friend's laptop, so at the moment it doesn't happen only on my desktop pc

SGaist

Then you should check with the drivers.
Does your friend laptop have the same specs as yours ?

Gibser

No, it has different hardware, but the video card is nvidia (949mx). At this point I'm wondering, will it be some library that I don't have on the laptop and cxfreeze didn't pack? How can I check, and if so, package the whole application correctly?

SGaist

The hardcore way would be to setup a minimal Python environment on one of these laptops to check that.

By crash do you mean it does not start at all ?

Gibser

It starts up, and I can browse widgets that don't have a Qt3DWindow. If I select ReconstructionWidget, which has this type of window, the GUI stays stuck on the same point if I select other widgets . However I can interact with the elements of the other widgets, I just don't see them because they are covered by the one with the 3d window. I can't even see the button animations, for example when I hover the mouse over them. Also, selecting the SegmentationWidget the app stops responding and I am forced to close. There are no errors in the terminal.

SGaist

Right, sorry, you wrote that in your initial post...

I would go with setting up a Python environment to check if it's working there.

Gibser

No problem, thanks for your time!
So I set up a new python environment. Do I install the packages gradually?

Gibser

I have implemented a basic app with a 3d window and a torus mesh, it works fine.
In the old app, I found that everything works if I comment

self.view.setRootEntity(self.rootEntity)

where self.rootEntity is a QEntity()

UPDATE:
It doesn't give problems when I set the root entity, but when I insert mesh, transform and material to a torus entity created as follows:

self.material = QPhongMaterial(self.rootEntity)
self.torusEntity = QEntity(self.rootEntity)
self.torusMesh = QTorusMesh()
self.torusMesh.setRadius(5)
self.torusMesh.setMinorRadius(1)
self.torusMesh.setRings(100)
self.torusMesh.setSlices(20)

self.torusTransform = QTransform()
self.torusTransform.setScale3D(QVector3D(1.0, 1.0, 1.0))
self.torusTransform.setRotation(QQuaternion.fromAxisAndAngle(QVector3D(1, 0, 0), 45))

self.torusEntity.addComponent(self.torusMesh)         # <-----   Problems from here
self.torusEntity.addComponent(self.torusTransform)
self.torusEntity.addComponent(self.material)

SGaist

Can you provide a minimal runnable script that triggers this ?
