QT GUI Widgets not working in 2022.01.20.dev #12

Closed tonycolo closed 2 years ago

tonycolo commented 2 years ago

File "tutorial1.py", line 124, in init self._qtgui_freq_sink_x_1_win = sip.wrapinstance(self.qtgui_freq_sink_x_1.pyqwidget(), Qt.QWidget) AttributeError: 'gnuradio.qtgui.qtgui_python.freq_sink_f' object has no attribute 'pyqwidget'

Same error for QT GUI Time sink. Windows 10, fresh install of 2022.01.20.dev

I think this is a GNU Radio 3.9 -> 3.10 change, and your tutorial1.py flowgraph needs to be recompiled with 3.10. If you don't have a GRC file to regenerate the .py file from, then I think all you should have to do is change pyqwidget() in that line to qwidget().

tonycolo commented 2 years ago

This is a flow graph created in GRC. I start with a blank flowgraph in 3.10.0 (rather than loading a previous one) and see the same result.

ryanvolz commented 2 years ago

That sounds like it's loading the block's YAML file from a different, older GNU Radio version. What is the output of

gnuradio-config-info --print-all

?

The prefix lines involving PothosSDR are surprising.

ryanvolz commented 2 years ago

Yeah, PothosSDR stomps on other GNU Radio installations. Run this from the Conda Prompt

conda env config vars set GR_PREFIX= GRC_BLOCKS_PATH= UHD_PKG_PATH= VOLK_PREFIX=

and then restart the prompt to run GRC. That should fix it, but maybe only for running from the prompt and not the Start Menu icon. Uninstalling PothosSDR would guarantee that it doesn't interfere, but I won't assume that you don't need it.

tonycolo commented 2 years ago

Thank you for helping me resolve. I had to rename/hide the PothosSDR directory.
