Hi so I am trying to do a least-cost-path analysis using Arcpy and I am trying to save the Cost Path raster
but I keep getting this error with the final line of the cost path tool. If I take out the save portion I am able to
convert it to a polyline, but I need data from the result. I used model builder to develop the script and only made
minor changes to some of the file paths. Any help would be greatly appreciated.

Error:
RuntimeError: ERROR 010240: Could not save raster dataset to C:\Users\doc34\Desktop\LCP_Project-20211206T164053Z-001\LCP_Project\CostPath_Raster with output format GRID.

Code:
# Process: Cost Path (Cost Path) (sa)

CostPath_Raster = "C:\\Users\\doc34\\Desktop\\LCP_Project-20211206T164053Z-001\\LCP_Project\\CostPath_Raster"
cost_path = CostPath_Raster

CostPath_Raster = arcpy.sa.CostPath(in_destination_data=Geological_Source, in_cost_distance_raster=CostDis_DEM,
in_cost_backlink_raster=BackLink_DEM, path_type="EACH_CELL",
destination_field="",
force_flow_direction_convention="INPUT_RANGE")
# the below code would save the cost-path raster, but throws an error that I have not been able to solve
CostPath_Raster.save(cost_path)
print("Cost Path Raster Complete")

If this is an esri raster, your output path shouldn't contain spaces or punctuation and the output name is too long (10 chars max I think).

You would be better off saving to a *.tif by adding the file extension to the file name.  *.tif files are recommended by esri for most raster functions


... sort of retired...

Yep I changed:

CP = "C:\\Users\\doc34\\Desktop\\LCP_Project-20211206T164053Z-001\\LCP_Project\\CostPath_raster"
to
CP = "C:\\Users\\doc34\\Desktop\\LCP_Project-20211206T164053Z-001\\LCP_Project\\CPR"
and it worked!
Thank you
