Upgrade to GNURadio v3.8 Python Issue?

[Jeff S]

I hope this is the correct list for this question.

I'm finally getting around to getting some PCs upgraded from 3.7 to 3.8.  I did the installs to a local prefix and everything seems to be running.  What I'm seeing, however, is when I have a ZMQ Pull Source added to my graph (picture of the simple graph attached), I'm getting some startup warnings a whole bunch of:

$ gnuradio-companion

<<< Welcome to GNU Radio Companion v3.8.2.0-88-g38f5ab7b >>>

Block paths:

/home/sdr/sdr/x310/installs/share/gnuradio/grc/blocks

Loading: "/home/sdr/jas/flow/untitled.grc"

/usr/lib/python3.6/importlib/_bootstrap.py:219: ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__

  return f(*args, **kwds)

I've searched the GNURadio Archives for "ImportWarning" to see what could be the issue and it doesn't seems to show up much.  I've checked my PYTHONPATH and LD_LOAD_PATH and I think they seem right (unless I'm not seeing the obvious):

$ echo $PYTHONPATH
/home/sdr/sdr/x310/installs/lib/python3/dist-packages:/home/sdr/sdr/x310/installs/lib/python3.6/site-packages:/usr/local/lib/python3/dist-packages:usr/local/lib/python2.7/site-packages:
$ echo $LD_LIBRARY_PATH
/home/sdr/sdr/x310/installs/lib:/user/local/lib:
$ gnuradio-config-info --prefix
/home/sdr/sdr/x310/installs
$ find /home/sdr/sdr/x310/installs -name gnuradio | grep "packages"
/home/sdr/sdr/x310/installs/lib/python3/dist-packages/gnuradio

Anyone see the obvious thing that I'm missing?

Thanks and regards,

Jeff
