[Discuss-gnuradio] cannot import name tv_rx

[Erik Tollerud]

I just got myself a TV_RX, and it works fine with the examples like
usrp_wfm_rcv, but when I run any of the tvrx specific examples
(particularly of interest is tvrx_tv_rcv.py), I get the following
python error
ImportError: cannot import name tv_rx

I tried changing it to db_tv_rx (as thats what I saw in the
site-packages directory), but it spit out a bunch of errors about no
global name tv_rx.  What's going on here?  did I somehow not get the
tv_rx package when I should have?
