直接调用模型 model出错

在arccatalog与arcmap中如果我们使用到扩展模块是要勾选的

python脚本中也需要进行验证

以3D模块为例：

C:\>python
Python 2.6.5 (r265:79096, Mar 19 2010, 21:48:26) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import arcpy
>>> arcpy.ImportToolbox("C:\HDDW_FB.tbx")
<module 'FB' (built-in)>
>>> arcpy.FB_FB()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\HDDW_FB.tbx", line 17, in FB

arcgisscripting.ExecuteError: Failed to execute. Parameters are not valid.
ERROR 000824: The tool is not licensed.
Failed to execute (FB).

>>>

此类问题以前的项目中也遇到过，现做下记录

解决办法：

# Check out any necessary licenses
arcpy.CheckOutExtension("3D")
