Installing PySide2 on Raspberry Pi

[Niagarer]

Hi,
I am trying to install PySide2 on my Raspberry Pi.

pip3 install PySide2

raises an error:

ERROR: Could not find a version that satisfies the requirement PySide2 (from versions: none)
ERROR: No matching distribution found for PySide2

Because I recently ran into problems with the config files and ssh modules, I just installed a fresh Raspbian image (version Feb 2020) but it still doesn't work. I found a couple of posts online of people experiencing the same but I haven't found a solution that worked for me yet.

• I am using Python 3.7.5 for which a wheel should be accessible
• I have updated and upgraded pip and the Pi to the newest versions

Any ideas...?
Thanks so much for help!

You can install PySide2 on the Raspberry Pi using the below command:
For python3:

apt-get install python3-pyside2.qt3dcore python3-pyside2.qt3dinput python3-pyside2.qt3dlogic python3-pyside2.qt3drender python3-pyside2.qtcharts python3-pyside2.qtconcurrent python3-pyside2.qtcore python3-pyside2.qtgui python3-pyside2.qthelp python3-pyside2.qtlocation python3-pyside2.qtmultimedia python3-pyside2.qtmultimediawidgets python3-pyside2.qtnetwork python3-pyside2.qtopengl python3-pyside2.qtpositioning python3-pyside2.qtprintsupport python3-pyside2.qtqml python3-pyside2.qtquick python3-pyside2.qtquickwidgets python3-pyside2.qtscript python3-pyside2.qtscripttools python3-pyside2.qtsensors python3-pyside2.qtsql python3-pyside2.qtsvg python3-pyside2.qttest python3-pyside2.qttexttospeech python3-pyside2.qtuitools python3-pyside2.qtwebchannel python3-pyside2.qtwebsockets python3-pyside2.qtwidgets python3-pyside2.qtx11extras python3-pyside2.qtxml python3-pyside2.qtxmlpatterns python3-pyside2uic

I am already using it (atleast the basic widgets) and so far it's working great without any issues.

@Niagarer if you can use Arch Linux ARM OS on the RPi device, you can follow these steps to have a full PySide2 installation:

1. Install PySide2

pacman -S pyside2

This action will install lots of dependencies: several X11 libraries; Qt 5.x and Python

2. Optional dependencies for pyside2

qt5-svg: QtSvg bindings
qt5-script: QtScript bindings
qt5-speech: QtTextToSpeech bindings
qt5-websockets: QtWebSockets bindings
qt5-webengine: QtWebEngine bindings
qt5-datavis3d: QtDataVisualization bindings
qt5-scxml: QtScxml bindings
qt5-sensors: QtSensors bindings
qt5-3d: Qt3D bindings
qt5-x11extras: QtX11Extras bindings
qt5-charts: QtCharts bindings
qt5-tools: QtHelp bindings
qt5-remoteobjects: QtRemoteObjects bindings

3. Missing library libQml

For the following error:

ImportError: libQt5Qml.so.5: cannot open shared object file: No such file or directory

fix by installing Qt QuickControls2

sudo pacman -S qt5-quickcontrols2

@Pablo-J-Rogina Thanks, I don't use ArchLinux, just normal Raspbian but your answer is surely helpful for other people.
Now, I just found this post where you also discussed that issue. Is PySide2 still unavailable for the Raspbian ARM? That would make me sad.

I don't know, but unfortunately a bug report about that is still open...

However, if you are dare enough :-) you may want to build it yourself.

By checking the PKGBUILD file from Arch Linux ARM you may have an idea of what packages you need to installed in your RPi device in order to build PySide2 directly in the board

@lolcocks Thank you! I also just found out about that, in the bug report @Pablo-J-Rogina posted, somebody mentioned it.
I do have a couple of little problems like

• setting the Background of QSpinBoxes via stylesheet doesn't work anymore
• using a file dialog fo an open file name sometimes has issues
• etc.

but overall it actually works way too good, I wasn't expecting that!
Now I am happy. Very happy.
For now this is solved I guess. If I run into huge problems, I will probably update here.

@lolcocks I did just this, and it seems to have installed everything correctly, but trying "import PySide2" within the venv that I installed everything gives a "no module named 'PySide2'". If, instead, I deactivate the venv and try to import the module, it works correctly. Any ideas?

[lbt_]

@ckarpis you've probably figured this out by now but for anyone else stumbling into this the answer is to create (or recreate) the venv with --system-site-packages

python3 -m venv your_venv_name --system-site-packages

If you're re-creating the venv you don't need to delete it - just rerun the command and it won't remove any existing modules you've installed in that venv.

Although some see it as 'bad form' to use this option it's much easier than trying to build/install pyside2 into each venv.

@lolcocks Thanks!
I had to add "sudo" at the begining of the command line to make it work on my raspberry Pi 3B+.
