'gr_top_block_sptr' object has no attribute '_setup_usrp'

Hi

I am trying to make digital-bert scripts work with USRP N200, RFX2400.
I
have changed my code a little bit. But it shows me an error saying
“object
has no attribute”.

[email protected]:~/gnuradio/gnuradio-examples/python/digital-bert$
./benchmark_tx1.py -f 2500M
linux; GNU C++ version 4.4.5; Boost_104200; UHD_003.001.002-ba0e3c8

gr_fir_ccf: using SSE
Modulation: 250k bits/sec
TX IF rate: 500k samples/sec
USRP interpolation: 256
DAC amplitude: 2000
Traceback (most recent call last):
File “./benchmark_tx1.py”, line 108, in
tb = tx_bpsk_block(options)
File “./benchmark_tx1.py”, line 52, in init
self._setup_usrp(options.ip,
File
“/usr/local/lib/python2.6/dist-packages/gnuradio/gr/top_block.py”,
line 94, in getattr
return getattr(self._tb, name)
AttributeError: ‘gr_top_block_sptr’ object has no attribute
‘_setup_usrp’

Can anyone help me out, how to resolve this error ? Attached is my
little
modified code.

two things that immediately leap to mind:

o Indentation matters in Python.  Your definition of _setup_usrp

isn’t within the class definition for tx_bpsk_block
o The most recent UHD doesn’t distinguish between “single_usrp” and
“multi_usrp”, there’s just a “usrp_source” and “usrp_sink”
object.

Hi

Thanks marcus. I am new to Gnu Radio and Python. I am working on
USRP N200 with RFX2400. I am trying to make digital-bert scripts to
work for UHD. I made some changes in the code but i am encoutering
errors. The latest error is shown below:
Looks to me like you’re trying to stuff a very-large floating-point
value into an integer. 32-bit integers are good to +/- 2**31, whereas
whatever value you have is very much larger than that. Usually, one
uses the error messages as a clue to debugging the code.

I got it what you are trying to say but i haven’t mentioned any integer
type
in the code so which very large value is it taking.
