Zonal Geometry and Zonal Geometry as Table crashing in Python window and Python standalone script

IanParfitt1

I'm attempting to use Zonal Geometry to identify narrow polygons using ArcGIS Pro 3.6.1.  I've tried both Zonal Geometry and Zonal Geometry as a Table.

1.  Zonal Geometry. The Zonal Geometry tool works in a minute or so in the desktop app and creates an output raster in my geodatabase with an uncompressed size of 577.76 MB (19629 columns x 7716 rows, 32 Bit floating point), but I'm not having joy with using Python.  The Python window in the app attempts to run, and I can see that *.tif files are created in the temp directory.  However, the function seems to spin on so I have ended after 60 minutes or so.  When I try to run as a standalone script I receive ERROR 000354: The name contains invalid characters. However, I don't see any name errors.

I want to run this for many jurisdictions identified by a string variable "jc", so I create a variable for the input grid (inGrid = "tmp" + jc ) which is a 0.2m resolution raster created from a feature class to raster conversion.  The class field is a long integer field (zoneField =  "PID_int") , the geometry metric is 'THICKNESS' and the cell size is 0.2m.  I also create a variable for the output (zgGrid = "zonegeo" + jc)

so the function looks like this:

zgresult= ZonalGeometry(inGrid, zoneField, 'THICKNESS', 0.2)

zgresult.save(zgGrid)

I have also tried making a raster layer first:

try:

        arcpy.management.MakeRasterLayer(inGrid, "out_rasterlayer")

        zgresult = ZonalGeometry("out_rasterlayer", zoneField, 'THICKNESS', 0.2)

        zgresult.save(zgGrid)

 

Same result: ERROR 000354: The name contains invalid characters

 

2.  Zonal Geometry as a Table.  When I run this function in a python window it also fails, but with a different error: ERROR 010067: Error in executing grid expression. create hash:

 

processingCellSize = 0.2

outgeoTab = "outgeoTab_" + jc

 

outZonalGeometryAsTable = ZonalGeometryAsTable(outGrid, zoneField, outgeoTab, processsingCellSize)

 

I am running on a reasonably well resourced laptop with plenty of storage space. I'm using VSCode as an IDE and have the correct python interpreter for this version or ArcGIS Pro / arcpy.

 

I use env.workspace to set the workspace to my geodatabase for this project.

I also use env.extent  and env.mask = inGrid in order to limit the processing as much as possible.

 

Thanks in advance for any ideas.

000354: The name contains invalid characters.—ArcGIS Pro | Documentation

invalid characters can include a period or a space, check your workspace path, perhaps copying the *.tif files to it and setting it as your temp or workspace folder (eg c:/testfolder is a good short simple path for inputs and outputs)
