Hello everyone, My system config: Host OS: Windows 10 Guest OS: VirtualBox Ubuntu 20.04.3 LTS UHD version: 3.15.0.0 GNU Radio version: 3.10.0.0 SDR Device : Ettus USRP N320
I have installed the gnuradio v3.10 recently, after the installation I got the below error in a simple QT GUI sink block > Window Type: [cid:[email protected]] The error is gone if I enter some integer value in the window type menu. But when I tried to build this flowgraph, I am getting the following catch exception error: Console logs: Generating: '/home/thangz/Desktop/gnuradio/rtlsdr_fm_spectrum_simple.py' Generate Error: 'catch_exceptions' >>> Failure Traceback (most recent call last): File "/usr/lib/python3/dist-packages/gnuradio/grc/gui/Application.py", line 720, in _handle_action generator.write() File "/usr/lib/python3/dist-packages/gnuradio/grc/core/generator/top_block.py", line 83, in write for filename, data in self._build_python_code_from_template(): File "/usr/lib/python3/dist-packages/gnuradio/grc/core/generator/top_block.py", line 123, in _build_python_code_from_template 'catch_exceptions': fg.get_option('catch_exceptions') File "/usr/lib/python3/dist-packages/gnuradio/grc/core/FlowGraph.py", line 182, in get_option return self.options_block.params[key].get_evaluated() KeyError: 'catch_exceptions' ^CTraceback (most recent call last): File "/usr/bin/gnuradio-companion", line 92, in <module> run_main() File "/usr/bin/gnuradio-companion", line 85, in run_main exit(main()) File "/usr/lib/python3/dist-packages/gnuradio/grc/main.py", line 85, in main sys.exit(app.run()) File "/usr/lib/python3/dist-packages/gi/overrides/Gio.py", line 44, in run return Gio.Application.run(self, *args, **kwargs) File "/usr/lib/python3.8/contextlib.py", line 120, in __exit__ next(self.gen) File "/usr/lib/python3/dist-packages/gi/_ossighelper.py", line 251, in register_sigint_fallback signal.default_int_handler(signal.SIGINT, None) KeyboardInterrupt Is there any fix/solution for this error?
