App crash

[Beforerr]

• SciQLop version: 0.5.4
• Python version: 3.12
• Operating System: macOS m2

Description

I tried to drag variables into the window like what the screenshot did, but got no response. Also the app closed whenever I tried to click the plus button or open a notebook and run.

It seems like a Qt/OS problem. But I had no experience with that.

What I Did

@Beforerr, I tried on both intel and M2 CPUs and wasn't able to reproduce the bug. Can you tell me more about your setup?

• Did you use a dedicated venv for SciQLop?
• How did you install python?
• Do you remember having any warning from pip about PySide version mismatch after installing SciQLop?

Mote that Python 3.11 and 3.12 are not supported by SciQLop yet because of this bug but it will only stop updating plots after some time not crash immediately as you described.

[Beforerr]

@jeandet I have downgraded the python into 3.10, but the app still instantly crashed when I tried to run notebook.

My environment could be found here link

[jeandet]

@Beforerr, I suspect it has something to do with conda and the way they build some binary packages that might not play well with PyPI ones. I won't be able to test with conda on a ARM based Mac in the next few days. One test you can do in the mean time, is to pull all dependencies with pip in a new clean environment.

[jeandet]

This might be related.

[Beforerr]

I tried only installed python and pip with conda and everything else with pip. Still, the app would crash when I tried to plot something in the notebook. It might be a PySide6 problem, so is it possible that we might downgrade some dependencies?

Also how could one drag the product into window and plot it?

[jeandet]

Sadly, it's not possible to downgrade PySide6 since both the plot and the dock widgets libraries are written in C++ and wrapped with PySide6 while PySide6 doesn't allow to mix different versions of itself.

To plot a product with drag and drop, you need first to create a plot panel with the plus icon in the top tool bar. Then you can drag and drop any product into it as long as it is a leave in the product tree.

Note also that I successfully tested SciQLop with python shipped by homebrew on a Mac mini M2.

[danieltomasz]

Coming from other discussion from other pachage, yhis might happen only on MacOS Sonoma due to coca binding with qt, pyside6 6.5.3 seems to work

[jeandet]

@danieltomasz weird, the machine I use for tests is running on Sonoma, does it also depend on which version of Sonoma?

[jeandet]

Same with latest stable Sonoma:

[danieltomasz]

I think it is the same problem https://bugreports.qt.io/browse/QTBUG-120181
I am on Apple Silicon, my guess would be that Intel might be spared from crashes, but architecture doesn't seem to be reported in the qt issue

[danieltomasz]

PySide6==6.6.0 seems to be working in other Python app, crashes starting with higher versions

[jeandet]

Once https://github.com/mborgerson/pyside6_qtads releases PySide 6.6.2 support, I'll push a release. In the mean time I should get a MacBook soon to investigate a bit more such issues.

[jeandet]

@Beforerr did you try a newer version of SciQLop? We used quite a lot on MacOs/ARM last week during a workshop.
The main issue on MacOs is that you should not close the welcome panel (it crashes the whole app). If you try to update SciQLop check that you use the exact versions for PySide, SciQLopPlots and PySide6-QtAds see here.

[jeandet]

@Beforerr I believe this have been fixed since few releases. Do not hesitate to reopen this bug if you still have this issue with the latest version.
