Python problem ?

[sidskeg]

Hi
Just tried running the GRC part and the following error appeared ;

File "/usr/local/lib/python2.7/dist-packages/dect2/console.py", line 27, in
from PyQt4 import QtCore, QtGui
RuntimeError: the PyQt4.QtCore and PyQt5.QtCore modules both wrap the QObject class

Any help gratefully received

Have you run the GRC file in gnuradio first or are you trying to execute the python file directly?

Hi
Downloaded everything from here, following the video, opened gnuradio, then opened the dect2.grc file and ran it. Then the error codes appeared.
I'm using kali-liux 2
Cheers

similar issue with dect2_Hackrf.grc:

If I use this hint from ttps://github.com/pavelyazev/gr-dect2/issues/10

git clone git://github.com/pavelyazev/gr-dect2.git
cd gr-dect2/
# Below one switches to the older QT4 branch:
git checkout pyqt4  
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig

the PyQt5 RuntimeError disappear and I get

[xscode]

I managed to sort this by converting the code to pyQT5. Change the file /usr/local/lib/python2.7/dist-packages/dect2/console.py to the one in my repo at
https://github.com/xscode/misc_scripts/blob/master/console.py

HEllo,
I use the modified console.py from xscode. Same issue, same error message.
RuntimeError: the PyQt4.QtCore and PyQt5.QtCore modules both wrap the QObject class
ubuntu 18.04 ; GNU Radio Companion 3.7.11
If anybody could help.
