Gr-air?

GNU Radio
1

Hi.

Found a set up article on how to set up gr-air:

http://superkuh.com/gnuradio/gr-air-modes_install.txt

I came to this step:

uhd_modes.py -d

And got this:

ERROR: uhd_modes.py has been deprecated. The new application name is
modes_rx.

After i ran this:

modes_rx -d

And got this:

Traceback (most recent call last):
File “/usr/local/bin/modes_rx”, line 25, in
from gnuradio import gr, gru, optfir, eng_notation, blks2
ImportError: No module named gnuradio

BTW Gnuradio is installed, and is running fine with gqrx.

How can I get out of this issue I have ?.

Thanks

I now know, that I shall run the modes_rx.

But I still get this:

Traceback (most recent call last):
File “/usr/local/bin/modes_rx”, line 25, in
from gnuradio import gr, gru, optfir, eng_notation, blks2
ImportError: No module named gnuradio

What is the , and where to find it ?

Erik

P.S. Is it the right mailinglist for the query ?

It is failing because Python can’t find the gnuradio module. gqrx is
working because it’s a C++ application and so doesn’t depend on the
Gnuradio Python module being installed.

What OS are you running (Ubuntu, Fedora, etc.), and what process did you
follow to install Gnuradio?

The gqrx app is C++ and could still find the GNU Radio native C++
libraries
and work normally even with the above.

Ah, thanks. I forgot gqrx was C++.

Erik,

What version of GNU Radio are you using?

You can also easily test this by hand. Just open ipython (or just
python)
and start importing by hand:

from gnuradio import gr
from gnuradio import gru
…

Figure out which one is actually failing for you.
