Warning: restarting the docstring loader (crashed while loading 'uhd_usrp_sink')


#1

Hi,

I recently installed the latest version of Gnuradio
(v3.7.9.2-279-gd7eaf6e1) using the following procedure:

sudo apt-get install git
sudo apt-get install cmake
sudo apt-get install python-pip
sudo pip install -U pip
sudo pip install PyBOMBS
sudo pybombs prefix init /usr/local -a usrlocal
sudo pybombs config default_prefix /usr/local
sudo pybombs recipes add gr-recipes
git+https://github.com/gnuradio/gr-recipes.git
sudo pybombs recipes add gr-etcetera
git+https://github.com/gnuradio/gr-etcetera.git
sudo apt-get update
sudo pybombs install uhd gnuradio
sudo ldconfig
sudo apt-get install gnuradio

I have a problem with the UHD block, in fact when I run

optirun gnuradio-companion

I obtain the following warnings:

Warning: restarting the docstring loader (crashed while loading
‘uhd_amsg_source’)
Warning: restarting the docstring loader (crashed while loading
‘uhd_usrp_sink’)
Warning: restarting the docstring loader (crashed while loading
‘uhd_usrp_source’)

If I try to use a UHD block, gnuradio crashes.

If I try to open gnuradio without bubblebee I can use all the blocks,
but when I use the USRP with the ‘uhd usrp sink’ block I obtain a lot of
Underun and then gnuradio crashes.

Do you have any clue?

Thanks in advance.
