How to upgrade qt 5.9.5 to 5.10.1 ??
-
Hi I'm planning to use PyQt5 on nvidia Xavier board which is arm64 architecture and Ubuntu 18.04.
I've been install PyQt5 using
sudo apt-get install python3-pyqt5
and checked the version of pyqt and qt it sayes
PYQT_VERSION = 330241
PYQT_VERSION_STR = 5.10.1
QOpenGLVersionProfile = <class 'PyQt5.QtGui.QOpenGLVersionProfile'>
QOperatingSystemVersion = <class 'PyQt5.QtCore.QOperatingSystemVersion'>
QT_VERSION = 329989
QT_VERSION_STR = 5.9.5Is it necessary to match the version of pyqt and qt? Is it the reason that getting error when using Qtgui.application ?
-
Hi and welcome to devnet,
No the numbers don't necessarily match.
What problem do you have ?

Thanks for the reply! If the version isn't a problem could you give me a solution about following errors..? I've been stuck in a week to figure out but can't get a solution,,
I;m running this script in python

Can you also share how you install your application dependencies. e.g. pyqtgraph.

I've installed pyqtgraph using got clone https://github.com/pyqtgraph/pyqtgraph.git system wide using
python3 setup.py installPyQt5 with sudo apt-get install python3-pyqt5
QtOpenGL with sudo apt-get install python3-pyqt5.qtopengl
and PyOpenGL with sudo apt-get install python3-opengl (3.1.0)
