Hi all,I'm using the Arc-SDM v. 10 (Spatial Data Modeler) tools in ArcGIS 10.1. I am trying to run a Weights of Evidence model (WOE) but keep receiving this error, even with the demo MXD and dataset:PYTHON ERRORS:
Traceback Info:
File "Z:\SDM\Scripts\NewCalcResp3.py", line 133, in <module>
gp.Lookup_sa(Temp_Raster,"WEIGHT",Output_Raster)
Error Info:
<class 'arcgisscripting.ExecuteError'>: Failed to execute. Parameters are not valid.
ERROR 001000: Lookup field: Field WEIGHT does not exist
Failed to execute (Lookup).
The model seems to run fine until it tries to calculate weights, then I run into this error. The code in question is: if NoDataArg != '#' and gp.describe(Input_Raster).pixeltype.upper().startswith('U'):
NoDataArg2 = '#'
else:
NoDataArg2 = NoDataArg
RasterLayer = "OutRas_lyr"
gp.MakeRasterLayer_management(Input_Raster,RasterLayer)
#++ AddJoin requires and input layer or tableview not Input Raster Dataset.
gp.AddJoin_management(RasterLayer,"Value",Wts_Table,"CLASS")
Temp_Raster = os.path.join(gp.scratchworkspace,'temp_raster')
if gp.exists(Temp_Raster): gp.delete(Temp_Raster)
gp.CopyRaster_management(RasterLayer,Temp_Raster,'#','#',NoDataArg2)
gp.Lookup_sa(Temp_Raster,"WEIGHT",Output_Raster)
I understand that gp.Lookup_sa is failing because the weight field does not exist in Temp_Raster, but I'm not sure how to resolve it. Any advice on how to troubleshoot this issue would be appreciated. I have emailed one of the SDM folks in charge of the project as well.Thank you!
