ClassifyRaster() Function not working

KarenSchulz

The function

arcpy.sa.Functions.ClassifyRaster(in_raster, in_classifier_definition, in_additional_raster='#')

is giving me the error RuntimeError: Object: Error in executing tool.

I set up the example analogue to Raster klassifizieren—Hilfe | ArcGIS for Desktop .

You can see the code in the following:

import arcgis
from arcgis.gis import GIS
from arcgis.raster import Raster

import arcpy
from arcpy.sa import *

from arcgis.raster.functions import *
from arcgis.raster.analytics import *

arcpy.CheckOutExtension("Spatial")

file_path = r"<path>.tif"
raster_test = Raster(file_path)

test_img = segment_mean_shift(raster_test, spectral_detail=None, spatial_detail=None, spectral_radius=None, spatial_radius=None, min_num_pixels_per_segment=None)

# file generated through graphical interface, because python code is not working as well

ecd_file = f"<path>/Preview_Segmented_TrainIsoCl.ecd"

ClassifyRaster(in_raster=test_img, in_classifier_definition=ecd_file)

I appreciate any help in solving this issue 😃

Not sure what you mean by that, but the warning in the help suggests something appears to be wrong with the inputs in a big way and I can't tell from your code (not sure what all the imports are needed for given the code examples in the help files)

The .ecd file contains all the information needed to perform a specific type of Esri-supported classification. The inputs to this tool must match the inputs used to generate the required .ecd file.

The .ecd file can be generated from any of the classifier training tools, such as Train Random Trees Classifier or Train Support Vector Machine Classifier.
