api python library : raise AttributeError(“No constructor defined”)
I'm trying to execute a python script using saga_api library, unfortunately I'm stopped in the first step :(. when I tray to execute this command on python: aga_api.CSG_Module_Library()
I have this error message:
def init(self, args, *kwargs):
raise AttributeError("No constructor defined")
AttributeError: No constructor defined
and it dose the same thing on windows !
Can you, please, help me to overpass this step ?!
System : Ubuntu 13.10 x64
python version : 2.7.5+
saga_api library version : 2.1.1
SAGA program version : 2.1.1
swig version : 2.0.10
This is the code:
!/usr/bin/env python
import saga_api, sys, os
def Import_raster(in__grid):
print saga_api.SAGA_API_Get_Version()

Library = saga_api.CSG_Module_Library() # here is the bug !!!
if Library.Create(saga_api.CSG_String(fmlb)) == 0:
print 'unable to load SAGA module library'
return 0
print '... success'
Module = Library.Get_Module('GDAL: Import Raster')
Parms = Module.Get_Parameters()
Parms('FILES').Set_Value(in__grid)
Parms('SELECT').Set_Value(1)
Parms('TRANSFORM').Set_Value(0)
Parms('INTERPOL').Set_Value(0)
Parms = Module.Get_Parameters(0) # additional parameter list
print Module.Get_Name() + ': ' + Parms('FILE').asString()
if Module.Execute() == 0:
print 'module execution failed'
return 0
print 'module successfully executed'
print 'save as SAGA grid'
if Parms('GRID').asGrid().Save(saga_api.CSG_String(in__grid)) == 0:
print '... failed'
return 0
print '... success'
return 1
if name == ' main ':

in__grid = '/home/.../CC432_landsat8.tif'
in__grid = os.path.abspath(in__grid)
else:
in__grid = sys.argv[1]
if os.path.split(in__grid)[0] == '':
in__grid = './' + in__grid
Import_raster(in__grid)
print "Done !"
