Dear Lokendra,
Thanks very much for your outstanding work.

Although the production of soil parameters is very smooth, I encountered some difficulties in making vegetation parameters.
In line 183 of vic_auto.py
arcpy.TableToTable_conversion("lulc_tab",arcpy.env.workspace,"temp_lulc.csv")
I want to know what is "temp_lulc.csv"？Did you miss the code to generate this file here?

Looking forward to your reply
