Run gr_specest

GNU Radio
1

Hi all:
I have installed the gr_specest toolbox successfully.And I use
the gnuradio 3.7.5.But when I run the specest_from_file.py,error
exists:

     File "/usr/local/bin/specest_from_file.py", line 142

SyntaxError: Non-ASCII character ‘\xce’ in file
/usr/local/bin/specest_from_file.py on line 142, but no encoding
declared; see PEP 263 – Defining Python Source Code Encodings | peps.python.org for details

Can someone explain it to me?Also I can't find the file 4cos.dat as

https://www.cgran.org/wiki/SpecEst#HowToRun shows.
Thank you so much.
Best regards,

That’s actually a bug; I’ve submitted a pull request. You can locally
use my change by doing
git pull GitHub - marcusmueller/gr-specest: A module adding spectral estimation routines to GNU Radio. fix_encoding

Greetings,

Sorry, my bad. Fixed my fix, should be clear now. Maybe you have to pull
–force, sorry about that.

I guess that is just an invocation example, so there is no 4cos.dat;
you should supply your own signal file.

In fact, it’s a bug in GNU Radio.

See: http://gnuradio.org/redmine/issues/707

Hi Marcus:
Thank you so much for your kindly reply.It now can
run.And I want to know where can I find the docuement 4cos.dat as some
examples shows.
Just like this:
specest_from_file.py -M welch -S 4cos.dat
4cos.dat: No such file or directory
