Problem with multimode.py: AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'

[sbfreddie]

Here is the terminal output:

Using Volk machine: ssse3_64_orc Traceback (most recent call last): File "/Users/freddie/bin/multimode.py", line 1099, in tb = multimode(ahw=options.ahw, freq=options.freq, ppm=options.ppm, vol=options.vol, ftune=options.ftune, xftune=options.xftune, srate=options.srate, upclo=options.upclo, devinfo=options.devinfo, agc=options.agc, arate=options.arate, upce=options.upce, mthresh=options.mthresh, offs=options.offs, flist=options.flist, dfifo=options.dfifo, mbw=options.mbw, deemph=options.deemph, dmode=options.dmode) File "/Users/freddie/bin/multimode.py", line 341, in init self.wxgui_waterfallsink2_0.set_callback(wxgui_waterfallsink2_0_callback) File "/usr/local/lib/python2.7/site-packages/gnuradio/gr/hier_block2.py", line 50, in getattr return getattr(self._hb, name) AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'

Perhaps this is the wrong forum to bring this up?

Thanks, Freddie

Yeah, this feels like an issue with multimode.py and not with your gnuradio installation. Feel free to reopen this issue if you find out otherwise from the authors of multimode.py.

Jonathan: I looks like the problem is caused by an older version of gnu radio. Check out this email I found:

This is almost certainly caused by having a version of Gnu Radio that isn't up-to-date. Are you sure you're running the version you think you're running? The GIT master of Gnu Radio has support for the 'set_callback' function used, but older ones don't.

It looks like a version problem, we need to update to a newer version of gnu radio.

Try brew install gnuradio --HEAD (I haven't tested this version)

[sbfreddie]

I tried using HEAD, but nothing has changed. gnuradio-companion works, but multimode.py still dies the same way.

Thanks, Freddie

HEAD is the latest version from git, so if it's a gnuradio version issue, that should have fixed the problem. I don't have any other suggestions, unfortunately.

I'm experiencing this same issue, fyi. gnuradio-config-info outputs v3.6.2.-1-ga4e2e8a9

After installing the homebrew gnuradio on a 10.7.4 machine, I also ran into the

AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'

error when trying to run multimode.py

After adjusting ~/.gnuradio/config.conf, then multimode.py returned:

RuntimeError: Unable to import OpenGL. Are Python wrappers for OpenGL installed?

After installing PyOpenGL-3.0.2b2, multimode.py is still not happy and dies with this error message:

Run into the same error above if I change config.conf to this:
