I am trying to develop some routing scripts using the arcpy.nax module, which was portrayed as being much better than the old arcpy.na module.
However, when I try to access any members of the module, Pylance complains with a "Not a known member" error.
As a tester, I copied the script on the Service Areas page, but am still having the same issue. Has anyone else run into this? I'm happy to continue developing against the older na module; however we'd like to migrate at some point.
The exact error is:
"MakeNetworkDatasetLayer" is not a known member of module "arcpy.nax" Pylance(reportGeneralTypeIssues)
Here's the code (from the docs), and the error screenshot is attached.
# An example showing how to perform service area analysis using a feature class for input facilities.
import arcpy
arcpy.CheckOutExtension("network")
nds = "C:/data/NorthAmerica.gdb/Routing/Routing_ND"
nd_layer_name = "Routing_ND"
input_facilities = "C:/data/io.gdb/Facilities"
output_polygons = "C:/data/io.gdb/ServiceAreaPolygons"
# Create a network dataset layer and get the desired travel mode for analysis
arcpy.nax.MakeNetworkDatasetLayer(nds, nd_layer_name)
nd_travel_modes = arcpy.nax.GetTravelModes(nd_layer_name)
travel_mode = nd_travel_modes["Driving Time"]
# Instantiate a ServiceArea solver object
service_area = arcpy.nax.ServiceArea(nd_layer_name)
# Set properties
service_area.timeUnits = arcpy.nax.TimeUnits.Minutes
service_area.defaultImpedanceCutoffs = [5, 10, 15]
service_area.travelMode = travel_mode
service_area.outputType = arcpy.nax.ServiceAreaOutputType.Polygons
service_area.geometryAtOverlap = arcpy.nax.ServiceAreaOverlapGeometry.Split
# Load inputs
service_area.load(arcpy.nax.ServiceAreaInputDataType.Facilities, input_facilities)
# Solve the analysis
result = service_area.solve()
# Export the results to a feature class
if result.solveSucceeded:
result.export(arcpy.nax.ServiceAreaOutputDataType.Polygons, output_polygons)
else:
print("Solve failed")
print(result.solverMessages(arcpy.nax.MessageSeverity.All))
