PySide2 example

[patrickelectric]

Is it possible to add an pyside2 example or add a reference of any pyside2 project that uses fbs ?

[mherrmann]

Good point. I've updated the tutorial:

You can also use Qt for Python instead of PyQt. To do this, simply write PySide2 instead of PyQt5 throughout this tutorial. For the above, use pip install PySide2 (without specifying a version).

You may also be interested in this PySide2 tutorial I wrote.

Thank you, I was able to use fbs run, but freeze fails.

It appears to be a problem with pyinstaller, related to this issue: https://github.com/pyinstaller/pyinstaller/issues/3689

[mherrmann]

Are you using Python 3.5 and PyInstaller 3.4?

[patrickelectric]

Python 3.7 and PyInstaller 3.4.

[fredrikaverpil]

I'm using the latest fbs with Python 3.7.1 and PyInstaller 3.4 without issues but I am primarily deploying on Windows and I am not using QtQuick.

For my particular PySide2 app, I need to make sure I have these hidden imports:

from PySide2 import QtXml
from PySide2 import QtUiTools

Judging by the error you posted, you might have to add QtQuick to your hidden imports.

[patrickelectric]

@fredrikaverpil thanks, but the problem is with pyinstaller. I'm developing under linux and doing some research with fbs and pyinstaller.

https://github.com/pyinstaller/pyinstaller/pull/3875 Does not fix everything but it's step closer to accomplish what I want.

@mherrmann With my last corrections with pyinstaller, I'm able to finish fbs freeze.

[mherrmann]

As mentioned in many places such as the tutorial, the Manual or the Troubleshooting page on fbs's web site, fbs only officially supports Python 3.5. I'm afraid I can't give help for 3.7 at this point.

[patrickelectric]

@mherrmann no problem, but is it possible to guide me if the problem is a consequence of fbs ? I would like to help and fix the issue.

Any idea ?

[patrickelectric]

It appears to a problem with pyinstaller yet, I'll try to debug it more and update it here.

[mherrmann]

As I said, I'll re-join this discussion when you are using Python 3.5 :-) The Python and PyInstaller versions are strongly interdependent, and I don't have time to chase problems that may just be caused by a wrong Python version. (Or present itself differently on different Python versions.)

[mherrmann]

Not sure which Linux distribution you are on but I just tested again on Ubuntu and can follow the tutorial flawlessly with Python 3.5, PySide2 5.11.2 and PyInstaller 3.4.

[patrickelectric]

I'm using Arch. Try with 3.7 to see if you can replicate the issue.

I will not try with 3.7. As I said, at the moment I only support 3.5. I can tell you however that fman actually uses 3.6 on Arch, so you may have some luck there.
