[GRASS-user] qgis and grass prosseses error.

Fri Sep 13 07:33:28 PDT 2019

Hello im student named Håvard taking a gis class in Norway. I keep getting the same error when trying to use grass in qgis and my teatcher told me to ask here since he had no Clue.
Under is the log from trying to do a V.rast.stats in qgis. The program Version are also here im not sure what to post either in this mail since i am really New to this.
