Run a custom model via ArcPy fails

I'm trying to geocode a few address using a custom model created. When running the model via model builder all runs perfectly.

Also when running it via the embedded interactive python console in ArcCatalog using the following code it also runs smooth.

>>> arcpy.ImportToolbox("C:\\Users\\jvidin\\AppData\\Roaming\\ESRI\\Desktop10.1\\ArcToolbox\\My Toolboxes\\usps_geocoder.tbx","geocoder")
<module 'geocoder' (built-in)>
>>> arcpy.geocoder_geocoder(
... 'gc_01', 
... 'J:/Postal/Postal/99_Geocode/01/composites/composite_1',
... 'J:/Postal/Postal/99_Geocode/01/composites/composite_2',
... 'J:/Postal/Postal/99_Geocode/01/gc.gdb/gc_01'
... )
... 
<Result ''>
>>> 

The problem occurs when trying to run it via IDE using the following code:

import arcpy

arcpy.ImportToolbox("C:\\Users\\jvidin\\AppData\\Roaming\\ESRI\\Desktop10.1\\ArcToolbox\\My Toolboxes\\usps_geocoder.tbx",
                    "geocoder")
try:
    arcpy.geocoder_geocoder('gc_01', 'J:/Postal/Postal/99_Geocode/01/composites/composite_1',
                        'J:/Postal/Postal/99_Geocode/01/composites/composite_2',
                        'J:/Postal/Postal/99_Geocode/01/gc.gdb/gc_01')
except Exception as e:
    print e.message

Thanks for support.
