Hi
I'm finalizing an in tree QTGUI eye_sink block. I use a GRC
example which was working fine until I decided to upgrade my local
GNURadiorepro (GnuRadio and Volk upgraded to latest commit on
January 5 2020, I was previously using 3.9 master uploaded in
November 2019 ).
- My eye_sink module is functional, however when using a
"channel model" I'm getting a python issue (I tested 2 different
channels with similar issue).
- Trying importing channels under python3 (from gnuradio import
channels) gives the same issue.
May be this can be related to
this commit ... but I did not succeeded in solving the
issue.
Regards, Christophe
