    Unfortunately the official Qt for Python packages using the pip wheel are not available for ARM platform.

    However, if you don't mind using Arch Linux ARM as the OS for your Raspberry Pi device, you can get the packages and tools (rcc, uic, etc.), both for armv7h and aarch64.

        @Marianagb it's just another possible Linux distribution you can install on Raspberry Pi devices

                @Pablo-J.-Rogina Alright, thanks, I guess I will go with the Arch Linux option only as migrating to C++ for the whole project will be too big of a task. Raspbian buster, which is an ongoing project to create complete Debian os for RPI will also work with PySide2.

                  @Pablo-J.-Rogina Have you tried installing PySide2 in arch linux arm. I installed arch linux in raspberry pi and have been trying to install the pyside2 using pacman manager but had no luck yet :(

                      Are you talking about Arch Linux ARM, right?

                      Yes, talking about Arch Linux ARM only.
                      Okay so I was able to install it using pacman manager only

                      [root@alarmpi alarm]# uname -a
                      Linux alarmpi 4.19.46-1-ARCH #1 SMP PREEMPT Thu May 30 13:54:52 UTC 2019 armv7l GNU/Linux
                      
                      [root@alarmpi alarm]#  pacman -Qlq pyside2
                      
                      ...
                      /usr/include/PySide2/QtCore/
                      /usr/include/PySide2/QtCore/pyside2_qtcore_python.h
                      ...
                      
                      

                      But whenever I try to run the following snippet of code

                      #!/usr/bin/python
                      import sys
                      from PySide2.QtWidgets import QApplication, QPushButton
                      from PySide2.QtCore import Slot
                      
                      @Slot()
                      def say_hello():
                       print("Button clicked, Hello!")
                      
                      # Create the Qt Application
                      app = QApplication(sys.argv)
                      # Create a button, connect it and show it
                      button = QPushButton("Click me")
                      button.clicked.connect(say_hello)
                      button.show()
                      # Run the main Qt loop
                      app.exec_()
                      

                      It is showing me this error

                      [root@alarmpi alarm]# python test.py 
                      Bus error (core dumped)
                      
                      

                      Not able to get any clue regarding this.

                        What version of of PySide2 do you have ?
                        What version of Qt ?
                        Did you try to run an equivalent C++ version of your application ?

                          What version of Qt ?

                          I just installed PySide2 in a freshly installed Arch Linux ARM running on raspberry pi. As far as I know, PySide runs long with Qt version >=5.11 .Correct me if am wrong, I don't need to build the Qt Core separately along with installing PySide2 in order to make it work ?

                            No you don't have to build anything. But still the exact version will be nice to have.

                            And please, try to build and run a dummy Qt widget application to see if it also fails.

                              PySide2 version is 5.12.13.

                              [root@alarmpi alarm]# python3
                              Python 3.7.3 (default, Mar 29 2019, 06:12:40)

                              Type "help", "copyright", "credits" or "license" for more information.
                              >>> import PySide2
                              >>> print(PySide2.__version__)
                              5.12.3
                              >>> 
                              

                              I tried running simple widget example test2.py as given below

                              import sys
                              from PySide2.QtWidgets import QApplication, QLabel

                              label = QLabel("Hello World!")
                              label.show()

                              It gave me the same error

                                That's why I asked you to test the C++ equivalent of your test application. To see whether it's a PySide2 or a mare general issue.

                                  @SGaist I built one c++ equivalent of a simple widget application for a raspberry pi kit and tried to run that. It gave me the same error i.e. Bus error(core dumped).
                                  I use the same kit in Qt Creator to build Qml based C++ apps to be run on raspberry pi running raspbian stretch and those apps run smoothly.

                                    Are you doing all of that directly on the Pi or are you cross-compiling ?

                                      I am cross compiling the app in a desktop.

                                        Then you have at least two versions of Qt on your target.

                                        Where are they located ?

                                          @SGaist I didn't get you exactly. I did a fresh installation of Arch Linux ARM and built PySide2 in it along with the required Qt packages. After doing all this I tried to run a simple PySide2 example and encountered the above error which I mentioned.
