Error in demo.py on Raspberry Pi

[andrew-veresov]

Hi!

I get an error when I run following command on RPi:

python demo.py eve.pmdl

Traceback (most recent call last):
File "demo.py", line 1, in
import snowboydecoder
File "/home/pirate/rpi-arm-raspbian-8.0-1.1.0/snowboydecoder.py", line 5, in
import snowboydetect
File "/home/pirate/rpi-arm-raspbian-8.0-1.1.0/snowboydetect.py", line 28, in
_snowboydetect = swig_import_helper()
File "/home/pirate/rpi-arm-raspbian-8.0-1.1.0/snowboydetect.py", line 24, in swig_import_helper
_mod = imp.load_module('_snowboydetect', fp, pathname, description)
ImportError: libf77blas.so.3: cannot open shared object file: No such file or directory

How can fix the issue?

Chances are you are missing a dependency

sudo apt-get install libatlas-base-dev

Give that a shot and then run it again.

Thank you that helped!

also I installed (don't know do I needed it really)

sudo apt-get install alsa-tools alsa-utils

and added my user to the audio group:

sudo usermod -a -G audio <user>

It is not working for me. After try to install libatlas-base-dev I got:

$ sudo apt-get install libatlas-base-dev

I tried this libatlas-dev, that asked for another and another. Finally, I got:

And I can't proceed. Can't install this libblas3 anymore:

libblas3 is already the newest version.

That is my sources.list:

$ sudo cat /etc/apt/sources.list
deb http://mirrordirector.raspbian.org/raspbian/ wheezy main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspbian.org/raspbian/ jessie main contrib non-free rpi

And my system version:

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Raspbian
Description:	Raspbian GNU/Linux 8.0 (jessie)
Release:	8.0
Codename:	jessie

Any help is welcome here :)

Thanks in advance.

It doesn't look like a Snowboy problem. Perhaps you messed your OS up? You could try to update the software source and perform the installation again. Guoguo

It made my initial error go away but the next error was

ImportError: dynamic module does not define module export function (PyInit__snowboydetect)

[chenguoguo]

Did you make under swig/Python or swig/Python3?

[hack-r]

Thanks you know I must be an idiot because I didn't see swig (I was looking in the unzipped .tar.bz.gz?) but I understand now that the project docs I'm following are out of date. They no longer use snowboy in the new Google AIY custom hot word fork for Pi so I will jump off this thread thanks for your help ⁣Sent from Blue ​

Could you post the repository fork? Thanks a lot. @hack-r

[hack-r]

@chenguoguo sure I was referring to https://github.com/shivasiddharth/GassistPi/

Try:
sudo aptitude install libatlas-base-dev
Instead of:
sudo apt-get install libatlas-base-dev
which might cause the probelm of independence
