New dependencies?

GNU Radio

Hi all,

I just updated gnuradio form git to
v3.6.4-86-g77743314 / 3.6.5git

Now one of my applications doesn’t run any more.
The call stack is:

Traceback (most recent call last):
File “./DisplayPngExample.py”, line 23, in
from grc_gnuradio import blks2 as grc_blks2
File
“/usr/local/gnuradio/lib64/python2.7/site-packages/grc_gnuradio/blks2/init.py”,
line 22, in
from packet import options, packet_encoder, packet_decoder,
File
“/usr/local/gnuradio/lib64/python2.7/site-packages/grc_gnuradio/blks2/packet.py”,
line 21, in
from gnuradio import gr, digital
File
“/usr/local/gnuradio/lib64/python2.7/site-packages/gnuradio/digital/init.py”,
line 45, in
from fftshift import fftshift, ifftshift
File
“/usr/local/gnuradio/lib64/python2.7/site-packages/gnuradio/digital/fftshift.py”,
line 24, in
from scipy import fftpack
ImportError: No module named scipy

And this is the conten of line 23

from grc_gnuradio import blks2 as grc_blks2.

I never had installed the scipy package before on my system ( gentoo, 64
bit version )

Is scipy now required ?

Many thanks

Volker

Hi Volker,

that file doesn’t need to be there.
To fix it straight away, apply this:

We’ll get that into master.
