AttributeError: ‘hier_block2_sptr’ object has no attribute ‘_hb’
marked protected they should not be accessed from outside the wrapper
directly (I remember some WXGUI code did that, but that has been fixed).
In the gnuradio tree I can’t seem to find anything like this.
Can you check and see from where this Exception is raised from?
The issue was in my python code that I derived from packet.py file. I
using this with 3.6.3
packet_source._hb.output_signature().sizeof_stream_item(0)) # Output
I replaced it with
packet_source.output_signature().sizeof_stream_item(0)) # Output
GRC flowgraph is working fine.
