v.kernel send a error message like:

"Impossible de démarer le module qgis.v.kernel.rast.py <http://qgis.v.kernel.rast.py> commande : /usr/share/qgis/grass/scripts//qgis.v.kernel.rast.py <http://qgis.v.kernel.rast.py> --interface-description" 

History

#1 Updated by Didier Genier about 8 years ago

To correct this bug I have modified the file /usr/share/grass/modules/v.kernel.qgm and changer module="qgis.v.kernel.rast.py" in module="v.kernel".
That's work.
Bests regards.

#2 Updated by Paolo Cavallini about 8 years ago

We have the same problem for all other .py GRASS scripts. They call --interface description, which is not available for the script (but it is for underlying GRASS module).

Which version of GRASS?

What happens if you run from GRASS shell (GRASS pure shell, not the shell in QGIS) the command:
your-path-where-qgis-is-installed/share/qgis/grass/scripts/qgis.v.kernel.rast.py --interface-description

For me it works with GRASS 6.4.0

#4 Updated by Paolo Cavallini about 8 years ago

With GRASS 6.4.1-1 from Debian sid it does not work, both with v.kernel and for db.connect-login.pg.py

#5 Updated by Radim Blazek about 8 years ago

For me
qgis.v.kernel.rast.py --interface-description
works in GRASS shell 6.4.1 compiled from source.

What output you get in GRASS shell?

#6 Updated by Paolo Cavallini about 8 years ago

The output form the shell is ok:
