I am trying to perform 'arcpy.Spatial Design Network Analysis.sDNAPrepare' command using ArcGIS Notebook on ArcGIS Pro (ver. 2.7.1). However, I have failed to run the command.

What is the problem and What should I do?

import arcpy
arcpy.ImportToolbox(r"D:/sDNA/sDNA.pyt")
arcpy.Spatial Design Network Analysis.sDNAPrepare(r"C:/Users/14009/Desktop/shanghai_sdna/shanghai_sdna_test/shanghai_network_center/shanghai_network_center.shp",  r"C:/Users/14009/Desktop/shanghai_sdna/shanghai_sdna_test/sdna_prepare_test/prepare_test.shp", None, None, "REPAIR", True, False, True, True, True, None, '', '', '', '', '', '')
-------------------------------------------------------------------
SyntaxError                       Traceback (most recent call last)

    You have space characters between the text "spatial design network analysis", that is invalid syntax as the error message indicates.

  • @user2856 you’re right - I mistook it for a picture and incorrectly voted to close it as a result.

The sDNA authors have used an invalid alias for the ArcGIS Toolbox.

You can set your own alias (module_name parameter) in arcpy.ImportToolbox. E.g

arcpy.ImportToolbox(r"D:/sDNA/sDNA.pyt", "sDNA") 
arcpy.sDNA.sDNAPrepare(r"C:/Users/etc...")
