Re: [Discuss-gnuradio] qt frequency sink runtime error

[Marcus Müller]

Huh, odd, that looks like it should, and that runs just well on my
3.7.12 (don't remember there being a related bug fix since 11); soooooo,
I'll need to read that couple lines of code in Python that your GRC
generates (and mine doesn't). Can you also share your
/tmp/resampler_demo.py ?

Thanks!
Marcus
