Query/issue in STM32MP157F-DK2

[Shail]

Hello Madam/sir,

Recently we have purchased STM32MP157F-DK2 development board, and we are very new to this board. We are trying to install PyQt5 on this board but we are getting error "Package not found" and also we are not getting proper link to install Python "GPIO Libraries"

So we required kind support for our future development by using this board.

Thanks and regards

Hello @Shail and welcome on our MPU platform.
How did you try to install PyQt5 libraries / packages ? 

I see that our distribution is able to provide PyQt5 stuff, but it will need some prerequisites :

• Working with Distribution Package (= compiling the complete distribution). You can find all the information on this wiki
• Check how to compile our default Qt example distribution here.
• You will see that a Yocto recipe for pyqt5 is present here in Yocto layers: meta-qt5/recipes-python/pyqt5/python3-pyqt5_5.15.1.bb

Then, you can try to modify your configuration file to add the pyqt5 into your build. It would seems like...

<build_yocto>/conf/local.conf:

<... already existing conf file ...>
IMAGE_INSTALL:append = " \
        python3-pyqt5 \
"

Then you can try something such as:

PC$> bitbake st-example-image-qt 

All of this is an example, but I advice you to well follow the wiki mentioned above to understand all these steps.
Regards,
erwan.

@Shail ,
One of my colleague have just let me realize that we provide this package on ST package repository.
The only thing you have to do is to link your board to an Ethernet connection, then :

apt-get update
apt-get install python3-pyqt5

See https://wiki.st.com/stm32mpu/wiki/Package_repository_for_OpenSTLinux_distribution for more information.
Kind regards,
Erwan.

I am grateful for your response and have successfully installed the PyQt5 library using the apt-get install python-pyqt5 command. I wrote a simple Python code using PyQt5 library, but when I run it, I am getting the following error.

"

Traceback (most recent call last):
File "/home/root/gui.py", line 2, in <module>
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton
ModuleNotFoundError: No module named 'PyQt5.sip'

"

Hello @Shail ,
Can you tell me the OpenSTLinux on which you are ? Is it OSTL v5.0 ?

Kind regards,
Erwan.

Hello @erwan,

Following OpenSTLinux is running on STM32MP157F-DK2.

ID=openstlinux-weston

Hello @Shail ,
I suspect we have an internal integration issue with this python3-pyqt5 package on the last OpenSTLinux. We are working on it to find a solution, I will let you know ASAP if we find a correction.

Kind regards,
Erwan.

Thanks & Regards,

app = QApplication([])

mainWin.setCentralWidget(button)
mainWin.show()

app.exec_()

and while i run this code i am getting following error.

Traceback (most recent call last):
