Error in executing tool (Focal Statistics)

Question

Hi, I'm really new at using python and I'm trying to create a script for terrain ruggedness index but I'm using 4 shapefiles. I want to convert them to rasters and then merge them and do the TRI on this one raster. My script keeps failing because of the RuntimeError: Object: Error in executing tool. I would be really grateful if anybody helps me. I got this: Traceback (most recent call last): File "F:\GIS_mag\py_nmg est.py", line 60, in arcpy.gp.FocalStatistics_sa(dmr, v3x3max, "Rectangle 3 3 CELL", "MAXIMUM", "DATA") File "c:\program files (x86)\arcgis\desktop10.5\arcpy\arcpy\geoprocessing\_base.py", line 510, in return lambda *args: val(*gp_fixargs(args, True)) RuntimeError: Object: Error in executing tool This is my script: # Import arcpy module import arcpy # Script arguments dmr1 = arcpy.GetParameterAsText(0) if dmr1 == '#' or not dmr1: dmr1 = "dmr1" # provide a default value if unspecified dmr2 = arcpy.GetParameterAsText(1) if dmr2 == '#' or not dmr2: dmr2 = "dmr2" # provide a default value if unspecified dmr3 = arcpy.GetParameterAsText(2) if dmr3 == '#' or not dmr3: dmr3 = "dmr3" # provide a default value if unspecified dmr4 = arcpy.GetParameterAsText(3) if dmr4 == '#' or not dmr4: dmr4 = "dmr4" # provide a default value if unspecified TRI = arcpy.GetParameterAsText(4) if TRI == '#' or not TRI: TRI = "F:\GIS_mag\py_nmg\tri" # provide a default value if unspecified # Local variables: dmr1_ras = "F:\GIS_mag\py_nmg\dmr1_ras" dmr2_ras = "F:\GIS_mag\py_nmg\dmr2_ras" dmr3_ras = "F:\GIS_mag\py_nmg\dmr3_ras" dmr4_ras = "F:\GIS_mag\py_nmg\dmr4_ras" dmr = dmr1_ras, dmr2_ras, dmr3_ras, dmr4_ras py_nmg = "F:\GIS_mag\py_nmg" v3x3max = "F:\GIS_mag\py_nmg\3x3max" v3x3min = "F:\GIS_mag\py_nmg\3x3min" # Process: Point to Raster arcpy.PointToRaster_conversion(dmr1, "Field3", dmr1_ras, "MOST_FREQUENT", "NONE", "1") # Process: Point to Raster (2) arcpy.PointToRaster_conversion(dmr2, "Field3", dmr2_ras, "MOST_FREQUENT", "NONE", "1") # Process: Point to Raster (3) arcpy.PointToRaster_conversion(dmr3, "Field3", dmr3_ras, "MOST_FREQUENT", "NONE", "1") # Process: Point to Raster (4) arcpy.PointToRaster_conversion(dmr4, "Field3", dmr4_ras, "MOST_FREQUENT", "NONE", "1") # Process: Mosaic To New Raster arcpy.MosaicToNewRaster_management("F:\GIS_mag\py_nmg\dmr1_ras;F:\GIS_mag\py_nmg\dmr2_ras;F:\GIS_mag\py_nmg\dmr3_ras;F:\GIS_mag\py_nmg\dmr4_ras", py_nmg, "dmr", "", "8_BIT_UNSIGNED", "", "1", "LAST", "FIRST") # Process: Focal Statistics (2) arcpy.gp.FocalStatistics_sa(dmr, v3x3max, "Rectangle 3 3 CELL", "MAXIMUM", "DATA") # Process: Focal Statistics arcpy.gp.FocalStatistics_sa(dmr, v3x3min, "Rectangle 3 3 CELL", "MINIMUM", "DATA") # Process: Raster Calculator arcpy.gp.RasterCalculator_sa("SquareRoot(Abs(Square("3x3max") - Square("3x3min")))", TRI)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You should mark this closed then Nina

The problem was the 'dmr' in lines 51 and 54, because at local variables it's defined as tuple made of 4 strings but the focal statistics method can only work with one, therefore I just changed the 'dmr' in lines 51 and 54 for "F:\GIS_mag\py_nmg\dmr" and now works perfectly fine.
Thanks for your help!

I would suspect that there is a disconnect between the script and the parameters unless you are running this as a tool within arcmap/PRO.

Throw in some print statements to print out your parameters at each stage before you get to the processing stage
