How can we change the label to Annotation for point layer through Arcpy(Python)?

[ManjariGoyal]

I am trying to convert the label for a point layer to annotation. Below is my script and the error I am getting.

import arcpy
from arcpy import env
import arcpy.mapping

# Set environment settings
env.workspace = "C:\Users\Documents"
arcpy.env.overwriteOutput = True

#define projection
Prjfile = r"C:\\Users\\Documents\\WGS1984.prj"
spRef = arcpy.SpatialReference(Prjfile)

#Local Variables

FC7 = r"C:\Users\Documents\South.gdb\Search_Ring"

mxd = arcpy.mapping.MapDocument(r"C:\Users\Documents\Demo_South.mxd")
df = arcpy.mapping.ListDataFrames(mxd,"Layers")[0]

## Convert Feature class to feature layer
arcpy.MakeFeatureLayer_management(FC7, r"C:\Users\Documents\Search_Ring.lyr")

layer7 = arcpy.mapping.Layer(r"C:\Users\Documents\Search_Ring.lyr")
Sym_layer7 = r"C:\Users\Documents\Search Ring.lyr"

## Apply symbology and add layer to MXD
arcpy.ApplySymbologyFromLayer_management (layer7, Sym_layer7)
arcpy.mapping.AddLayer(df, layer7, "TOP")
lyr7 = arcpy.mapping.ListLayers(mxd, "", df)[0]

## Add the labels and its format
lyr7.labelClasses[0].expression = '"{}" + [Candidate_Code] + "{}"'.format("<CLR blue='255'><FNT size = '9'><BOL>", "</BOL></FNT></CLR>")
lyr7.showLabels = True

## Convert label to Annotation
arcpy.ConvertLabelsToAnnotation_defense (mxd, "")

## Add Layer Properties
lyr7.visible = False
lyr7.name = "Search_Ring"
lyr7.maxScale = 0;
lyr7.minScale = 5000000;
lyr7.transparency = 25;

arcpy.RefreshActiveView()
arcpy.RefreshTOC()

## Save the mxd
mxd.saveACopy(r"C:\Users\Documents\South.mxd")

del mxd,df

ERROR:

Any help is appreciated.

Thanks

have you enabled the extension?

Seems like I don't have this defense mapping extension. Is there any other way to do it.

I don't use them but the only other references are to lessons or the military analyst
