[Discuss-gnuradio] run gr_specest

[xianda]

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 http://www.python.org/peps/pep-0263.html 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,
