I am trying to run a GNURadio flow graph that runs fine on my Windows computer but gives me an error on my Raspberry Pi. The error is:
No module named _osmosdr_swig
For some reason line feeds in my perfectly formatted text in these entry fields get removed when I post. The format instructions say, "for linebreak add 2 spaces at end" but I can't get that to work.
I have tried to add a second line feed to each line. I hope I didn't miss any.
I just don't know enough Python to understand what is happening.
Here is what GNURadio reported:
Traceback (most recent call last):
