arcmap中的焦点统计一直未响应

当我调用arcmap中的焦点统计时一直未响应，重启了好几次也没用，我猜呢，可能是我用的中文版的，出BUG了。

解决办法：就是用arcgis自带的python2环境来编写（焦点统计的代码）实现相应功能。代码如下：

# Name: FocalStatistics_Ex_02.py
# Description: Calculates a statistic on a raster over a specified
#    neighborhood.
# Requirements: Spatial Analyst Extension
# -*- coding: utf-8 -*-
# Import system modules
import arcpy
from arcpy import env
from arcpy.sa import *

# Set environment settings
env.workspace = r'E:\arcjs\luding\redundant.gdb'

# Set local variables
inRaster = "projection"
outRaster = "STD_dem_project"
neighborhood = NbrRectangle(20, 20, "CELL")

# Check out the ArcGIS Spatial Analyst extension license
arcpy.CheckOutExtension("Spatial")

# Execute FocalStatistics
outFocalStatistics = FocalStatistics(inRaster, neighborhood, "STD",
                                     "")

# Save the output 
outFocalStatistics.save(outRaster)
print('{}success'.format(outRaster))
