ah, it seems the python script you included in the model is probably from arcgis 9.3 or prior, which used different syntax for certain tools then what is being used for 10.0 to current. the gp you see is the older version syntax they used.
If you could post the python script that was included in the model, we could probably help you debug or update it so it can run for 10.0 - 10.2
Hi Thank You so much for reply and helping me, just to add the model runs completely smooth and how its intended to do, in ArcMap 10.But here is the script hopefully u guys can help me.import os, sys, random, arcgisscripting
try:
gp = arcgisscripting.create()
gp.overwriteoutput = 1
# Specify input featureclass, output *.lyr file and the percentage of
# random points to return. Set these parameters in ArcToolbox as shown.
inputFC = sys.argv[1] # Feature Class or Feature Layer
outputLyr = sys.argv[2] # Layer File
inpct = sys.argv[3] # Long
# Ensure that the input percentage is between 1 and 100%
inpct = min(int(inpct),100)
inpct = max(int(inpct),1)
# Work out how many features to select
inputDirname = os.path.dirname(inputFC)
inputBasename = os.path.basename(inputFC)
gp.workspace = inputDirname
desc = gp.describe(inputFC)
totpnts = gp.getcount(inputFC)
numValues = int(round(totpnts * float(inpct) / 100.0))
gp.addmessage("Selecting " + str(numValues) + " random features")
# Generate a list of all features, and select randomly from this
inList = []
randomList = []
fldname = desc.OIDFieldName
rows = gp.SearchCursor(inputFC)
row = rows.next()
gp.addmessage ("Loading all IDs into a list")
while row:
id = row.GetValue(fldname)
inList.append(id)
row = rows.next()
selpnts = 0
gp.addmessage("Creating the list of randomly selected features")
while len(randomList) < numValues:
selpnts += 1
selItem = random.choice(inList)
randomList.append(selItem)
inList.remove(selItem)
# Select features whose OID value occurs in the random list, generate
# a *.lyr file from this selection. (Leading and trailing [ and ] marks
# need to be removed from the list object)
theLen = len(str(randomList))
sqlexp = '"' + fldname + '"' + " in " + "(" + str(randomList)[1:theLen - 1] + ")"
selectionLyr = inputBasename + " selection"
gp.MakeFeatureLayer_management(inputFC, selectionLyr, sqlexp)
gp.SaveToLayerFile_management(selectionLyr, outputLyr)
gp.addmessage("\nOutput layer " + outputLyr + " contains features randomly selected from " + inputBasename + "\n")
except:
gp.adderror("Error running script. Try specifying the full path to the input layer")
