ArcHydro doesn't recognize workspace or target locations in Python ?

Question

I'm currently busy re-writing the following Python Module: * ArcHydro Pre-processing I have just realised that ArcHydro doesn't recognize the arcpy.env.workspace or the ArcHydroTools.SetTargetLocations("HydroConfig", "Layers", "RasterWorkspace", "VectorWorkspace") ''' Created on March 13, 2017 ArcHydro Main Model @author: PeterW ''' # import system modules and site-packages from pathlib import Path import arcpy import ArcHydroTools # set arguments rasters_workspace = r"E:\Projects\2016\G113386\ArcHydro\Model01\Layers01" dem = r"E:\Projects\2016\G113386\DEM\raw" fgdb_workspace = r"E:\Projects\2016\G113386\ArcHydro\Model01\Model01.gdb" # check out extensions and set environment settings arcpy.CheckOutExtension("Spatial") arcpy.env.overwriteOutput = True def rasters_main(rasters_workspace, dem): """ Create Rasters as part of ArcHydro Pre-processing""" # set raster workspace arcpy.env.workspace = rasters_workspace # set ArcHyro Target Locations for Raster and Vector Datasets ArcHydroTools.SetTargetLocations("HydroConfig", "Layers", rasters_workspace, fgdb_workspace) # create Fil Sinks raster arcpy.AddMessage("Processing Fill Sinks") ArcHydroTools.FillSinks(dem, "fil") # create Flow Direction raster rasters_main(rasters_workspace, dem)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Python Module: arcpy.env.workspace and ArcHydroTools.SetTargetLocations ignored by ArcHydro Processing Fill Sinks Traceback (most recent call last): File "E:\Python\Eclipse\2015\arcpy64bit\src\archydro\archydro_main_test.py", line 34, in <module> rasters_main(rasters_workspace, dem) File "E:\Python\Eclipse\2015\arcpy64bit\src\archydro\archydro_main_test.py", line 31, in rasters_main ArcHydroTools.FillSinks(dem, "fil") File "C:\Program Files\ESRI\WaterUtils\ArcHydro\bin\ArcHydroTools.py", line 6805, in FillSinks raise e arcgisscripting.ExecuteError: You need to set either the geoprocessing Workspace or the Arc Hydro Raster Location before running the tool.

I don't know if this will fix your problem, but I was having a similar issue (except with vector location instead of raster location) with ThinCrossSection tool even though I set the arcpy enviroment and ArcHydro's target locations. The issue seems to be that you need a full path to a feature instead of just the name: # This did not work for me ArcHydroTools.ThinCrossSection("TEMP", "MaxNumberOfVertices", 500, output, report) # This did output = gdb_path + '\' + output report = gdb_path + '\' + report ArcHydroTools.ThinCrossSection("TEMP", "MaxNumberOfVertices", 500, output, report)‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ And with this, I just had to set the arcpy workspace - I don't need to call SetTargetLocations from ArcHydro. So specifically for yours, replacing 'fil' in the FillSinks call with the full path to 'fil' might work
