Error in executing tool (Focal Statistics)

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\", line 60, in <module>, v3x3max, "Rectangle 3 3 CELL", "MAXIMUM", "DATA")
File "c:\program files (x86)\arcgis\desktop10.5\arcpy\arcpy\geoprocessing\", line 510, in <lambda>
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"

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"
