Hello,
I have installed GnuRadio 3.10.1.1 and Python 3.10.4 on Ubuntu 22_04
and I run into a problem:
There is only a very simple flowgraph:
QT GUI Toggle Switch --> QT GUI LED Indicator
At runtime, there is an error in modul:
"/usr/lib/python3/dist-packages/gnuradio/qtgui/ledindicator.py", line 79
As I can see, there is a type mismatch between float and whatever?
Has anybody an idea what goes wrong and how can I fix it?
Thanks
Karlheinz Kemna
