Hi Guys,
Thanks very much for the assistance!! The problem was that I hadn't
installed the UHD binary from Ettus (I feel like a bit of an idiot, I should
have worked that out). Once I did that, and included the path in my
environmental variables, I no longer received any errors when running:
python.exe -c "from gnuradio import uhd".
Unfortunately this hasn't cleared up my other problem. I'm still getting
this error when I try to run a simple flow graph in Gnu Radio Companion:
Generating: "C:\Program Files (x86)\gnuradio\bin\top_block.py"
Executing: "C:\Program Files (x86)\gnuradio\bin\top_block.py"
[Error 2] The system cannot find the file specified
>>> Done
The graph I created is very simple and is composed of: a signal source, a
throttle, and a QT GUI Sink. It seems that the top_block.py is actually
created (I can see it in windows explorer), but it Gnu Radio Companion
doesn't seem to be able to find or run the file. Just in case it helps, I've
added the file's contents below my e-mail. Do you guys have any idea as to
what could be causing this?
Thanks again and kind regards,
Ryan
