Hello, as some of you may know I recently installed a fresh GNURADIO package, after a manual install of a UHD package on my Ubuntu 10.04 LTS workstation. dpkg -i UUHD-003.003.001-Ubuntu-10.04-x86\_64.deb (from git) cat version.sh MAJOR\_VERSION=3 API\_COMPAT=5 MINOR\_VERSION=0rc0 MAINT\_VERSION=0 So far so good, Gnu Radio Companion works etc., uhd\_fft.py, Audio examples work etc. My test setup: USRP/TVRX2 – USB – USB (UHD) – HOST However, as I had attempted earlier installs, some old files remain. My question is: are the files provided in the following list already deprecated? The majority of them include “from gnuradio import usrp” or “from gnuradio import usrp2” string in their header, and I have confirmed even the most basic example listed in [http://www.joshknows.com/gnuradio](http://www.joshknows.com/gnuradio) (See USRP Examples) fails. So, is there a recommended way to modify these python files to use the UHD driver instead of (missing?) USRP or USRP2 blocks? If these files will not be needed anymore (as UHD supercedes USRP), why keep them around on public websites? But if they have any educational value, then why not keep a “stub” usrp entry that spits out an error message to the calling script with a blurb of something like “feature deprecated, please use UHD”… so that old code examples can be ported to newer coding standards? Traceback (most recent call last): File “foo.py”, line 2, in from gnuradio import usrp ImportError: cannot import name usrp Now a general question for the archive-maintainers, is there a handy reference of the supported/tested status of each of these files? I see that (I believe…) none of the files have a timestamp or author information, or even a specification block as to the exact test environment this code was executed in. Is that information available elsewhere as a release note accompanying the package or only available through a git log entry?
