maemo.org - Talk - [SCRIPT] Using the N900 as Sonar

Hi to all,I try use this script,so what i did?
Install python-numpy and alsa-utils(that package i already have) and python2.7,also i created emty file with leafpad(also i try to created file using windows but result it was the same)and rename him echo.py,then copy sonar script from pastebin and paste in echo.py
but when type python2.7 echo.py the output from console is:

Quote:

~ $ python2.7 echo.py
Traceback (most recent call last):
File "echo.py", line 9, in <module>
import numpy as npy

import multiarray
ImportError: No module named multiarray

I made quick search and found this http://askubuntu.com/questions/23090...med-multiarray
although than,i follow advice from above link,that mistake show me again,anyone from you has experience with this script

regards
edit:finally i manage to run this script(after several time i created and deleted folder numpy and the end i left that folder in /usr/local/lib/python2.7/site-packages/)
but for big regret my sonar on n900,won't detected any movement
but this time i type python echo.py
what the F*******
