脚本中shp文件在arcgis10.1下可以访问。在10.3下貌似不行

arcgis10.1下可以运行。在10.3下不行

import arcpy,os

# input data 
input_layer = r'D:\test03\shp\all.shp'
split_field = r'NAME'

#
with arcpy.da.SearchCursor(input_layer, [split_field]) as cursor:
    for row in cursor:
        print row[0]

在10.3下

import arcpy,os

# input data
arcpy.en.workspace=r'D:\test03\shp    #10.3下存放shp的文件夹设为工作目录才行
input_layer = 'all.shp'
split_field = r'NAME'

#
with arcpy.da.SearchCursor(input_layer, [split_field]) as cursor:
    for row in cursor:
        print row[0]
