i use the gdb as you said,the i debug the python file again
run the fie step by step
i found that the there is some problem with ‘channel model’,just like
you can see that
self.channels_channel_model_0 = channels.channel_model(
function is init the channel model block
and the noise_voltage =0.0001 ,frequency_offset=0 and so on is the parameter of 'channel model'
after the parameter is inited,the program should call the
Subroutine to pass this parameters,but you can see that the program aborted,
then i use command p to view the value of self.channels_channel_model_0,but i got the output
there is no attribute of this ,in other words
i think that there is some problem with the channel model in the pre-installed gnuradio.
hope you can confirm this problem
