In QGis 2.2 all my models (processing model builder) are working fine. When I start the same models in 2.4 I get errors like this:

Prepare algorithm 5: Zonal Statistics Running Zonal Statistics [6/8] Parameters: RASTERLAYER_RASTER =C:\Temp\processing\779310258f5d4cc5a0d3f0c747b2627f\RESULT.tif, VECTORLAYER_GRENZEN =C:/Tempordner_GIS/ASL_EK/Bereinigt/018-01/DGM5_UTM32_6stell.shp Prepare algorithm 0: Zonal Statistics Running Zonal Statistics [1/1] Parameters: INPUT_RASTER =C:\Temp\processing\779310258f5d4cc5a0d3f0c747b2627f\RESULT.tif, RASTER_BAND =1, INPUT_VECTOR =C:/Tempordner_GIS/ASL_EK/Bereinigt/018-01/DGM5_UTM32_6stell.shp, COLUMN_PREFIX =_, GLOBAL_EXTENT =True Failed Failed Error executing algorithm 5 Error executing algorithm 0 'NoneType' object has no attribute 'GetGeoTransform' See log for more details

This is the error log:

Uncaught error while executing algorithm Traceback (most recent call last): Traceback (most recent call last): File "C:/PROGRA~1/QGISCH~1/apps/qgis/./python/plugins\processing\core\GeoAlgorithm.py", line 217, in execute self.processAlgorithm(progress) File "C:/PROGRA~1/QGISCH~1/apps/qgis/./python/plugins\processing\algs\qgis\ZonalStatistics.py", line 78, in processAlgorithm geoTransform = rasterDS.GetGeoTransform() AttributeError: 'NoneType' object has no attribute 'GetGeoTransform'

Has anyone a tip for me?

  • Could you not re-create your models in QGIS 2.4? Also, do you have both QGIS 2.2 and 2.4 installed? I'm only guessing that there might be a conflict issue...?

  • When I re-create them it obviously works! But this would be a lot of work.

    In QGIS 2.4, there may have been changes to the core plugins code which could differ from QGIS 2.2. Perhaps you can save your model from 2.2 as a Python script, load the script into 2.4 and run it as a script. You will be told on which line the error(s) is which might make it easier to debug (if you know a little Python). But hopefully someone could provide much more helpful advice than me :)

  • Thanx for the tip. I have never worked with python scripts. Is it easy to re -import the model (I saved it as a python script)?

  • Processing Toolbox > Scripts > Tools, you can either add the script from file or very simply copy/paste into a new script. Remember to save it in C:\Users(your user name)\.qgis2\processing\scripts (this is the directory for 2.2, not sure if 2.4 uses the same)
