Weighted Overlay Table Invalid Class

JacobSpear1

I'm trying to run a weighted overlay on two separate integer rasters. I built the original overlay model in arcpro and exported the tool as script. I then modified the script to fit the syntax as shown on the ESRI help pages. Now when I run the script I receive (Unspecified error Class not registered).  The landcover and slopeint classes reference existing raster files in the environment gdb. I have cropped out the middle portion of the script that prepares the rasters.

What did I do wrong?

#Import modules
import arcpy
from arcpy.sa import *
from sys import argv

LandCover = "LandCover"
slopeint = "slopeint"

intable = WOTable([[slopeint, 50, "Value", RemapValue([[0, 3], [1, 3], [2, 3], [3, 3], [4, 3], [5, 3], [6, 3], [7, 3], [8, 3], [9, 3], [10, 3], [11, 3], [12, 3], [13, 2], [14, 2], [15, 1], [16, 'Restricted'], [17, 'Restricted'], [18, 'Restricted'], [19, 'Restricted'], [21, 'Restricted'], [22, 'Restricted'], [23, 'Restricted'], [24, 'Restricted'], ["NODATA", "NODATA"]])], 
                     [LandCover, 50, "Class", RemapValue([['Open Water', 'Restricted'], ['Perennial Snow/Ice', 1], ['Developed, Open Space', 3], ['Developed, Low Intensity', 2], ['Developed, Medium Intensity', 1], ['Developed, High Intensity', 'Restricted'], ['Barren Land', 3], ['Deciduous Forest', 'Restricted'], ['Evergreen Forest', 'Restricted'], ['Mixed Forest', 'Restricted'], ['Shrub/Scrub', 2], ['Herbaceuous', 2], ['Hay/Pasture', 3], ['Cultivated Crops', 3], ['Woody Wetlands', 'Restricted'], ['Emergent Herbaceuous Wetlands', 'Restricted'], ['NODATA', 'NODATA']])]], 
                    [1, 3, 1])
helicoptersuitability = WeightedOverlay(intable)
helicoptersuitability.save("helicoptersuitability")

I don't know.  But even though the whole input to the weighted overlay tool is raw encoded (r" ... ) the paths of the inputs and outputs are not.

'D:\Documents\School\USC\586\586_Project_5\Project_5\Project_5.gdb\slopeint'

yields errors which vanish when done as

r'D:\Documents\School\USC\586\586_Project_5\Project_5\Project_5.gdb\slopeint'

You might want to try different gdb (saving location or raw encode the file paths in the above lines and try it from within your python IDE
