Hi Marcus,
According to the build/install_manifest.txt it installs to:
/usr/local/lib/python2.7/site-packages/
And various other /usr/local/ paths as appropriate e.g. /usr/local/include/
/usr/local/share/
Does that make sense?
I followed the instructions - exactly - to use gr_modtool to create a module,
then add a block... I make a build directory and use the cmake, then make then
sudo make install commands as per instructions...
When I had not updated the pythonpath to include the install location I got the
import error. After that was fixed I get the attribute error of this kind:
Traceback (most recent call last):
File "square_floats.py", line 159, in <module>
main()
File "square_floats.py", line 147, in main
tb = top_block_cls()
File "square_floats.py", line 113, in __init
self.howto_square2_ff_0 = howto.square2_ff()
AttributeError: 'module' object has no attribute 'square_ff'
which is only fixed by the aforementioned kludge.
Investigating this showed that it is going to the installed module in the
pythonpath - it's only when I successfully alter that that it works!!
If said file only has for example:
from howto_swig import *
then it will not work but will throw the attribute error.

Jacqueline

Hi Jacqueline,
hm, I see! But where *did* you then install your gr-tutorial to, then (if in
doubt, look into build/install_manifest.txt)? Point is that the *installation
target* should be part of your python path, not the source (/python) nor the
build (/build) directories.
Best regards,
Marcus

Hi Marcus,
I know it's a kludge but I've been working on this steadily when I can to try
and work out why it hasn't been working despite following all directions in the
tutorials, and so far this is the only way to get it to work.
It's how I got the python and C++ blocks in the Guided Tutorials to work and
then I tried again with the square_ff() OOT modules tutorial thinking it must
have been something I did wrong. I fixed a few other issues I had via that
route (I had 'orphan' modules in the GRC) but I still had these runtime errors
when I tried to run the 'howto' blocks.
I didn't use pybombs to install - I haven't touched pybombs. As I'm on Arch, I
installed everything from the Archlinux packages using pacman.
Since I've been going through this second sequence of tutorials I've had no
problems and no error messages with make and make install! So there's no hint
it's not going to work until runtime.
I did get an ImportError initially but I fixed that by setting the PYTHONPATH
properly.

Hi Jacqueline,
that is not a fix I'd recommend - if this is really just all it takes to get
your module running, than plainly, something has gone wrong with installing the
gr-tutorial module. Did "make install" work well? Where did things get
installed to? Is that installation target right inside your pybombs prefix?
Best regards,
Marcus

Hi Tellrell and others,
I have been having similar problems while going through the various tutorials
and have come up with some workarounds (with help from a python expert - my 21
year old son) and am now getting to the bottom of it.
I have fixed it by adding the following lines to the -_init__.py file and then
re-doing the make and make install steps so that it gets compiled into the
site-packages directories in the PYTHONPATH.
import sys
sys.path.append("/your-home-path/gr-tutorial/python/")
sys.path.append("/your-home-path/gr-tutorial/build/")
sys.path.append("/your-home-path/gr-tutorial/build/swig/")
I suppose I could add these paths to the sys path and that would fix the
problem once and for all.

Jacqueline

Hi Tellrell -
It looks like your `gr-inspector` OOT module isn't getting found by GNU Radio.
How did you install it? Are you using PyBOMBS? Are you sure you installed it
into the same directory as GNU Radio?
Cheers,
Ben

I'm running the live_signal_detection. I replaced the rtlsdr_source block with
a signal source block. When I run the flowgraph I get
"attributerror: Module object has no attribute 'signal_detector_cvf"
I tried deleting and reinstalling all the dependencies before installing
gr-inspector but I'm getting the same result.
