[ITK-users] Using ITK python wrapper

Tue Apr 1 04:44:32 EDT 2014

Thank you for everyone getting back to me. I have had a play with the
paths, and carried out all your suggestions. But I still have no luck. The
problem I have firstly with the paths is that my itk.py file is
sys.path.append('C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/Release'),
along with itkBase.py, itkConfig.py, itkLazy.py, itkTemplate.py,
itkTypes.py and the WrapITK.path.

There is no itk.py in
sys.path.append('C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python')
that was suggested, but what I do have is InsightToolkit.py here (amongst
many other python files). When I import InsightToolkit.py (after adding the
lib path), I get this error:

>>> import InsightToolkit

Traceback (most recent call last):

File "<console>", line 1, in <module>

File
"C:\Toolkits\ITK-4.5.1\build_x64_VS2008_withLTK\Wrapping\Generators\Python\Configuration\..\InsightToolkit.py",

from ITKPyBase import *

File
"C:\Toolkits\ITK-4.5.1\build_x64_VS2008_withLTK\Wrapping\Generators\Python\Configuration\..\ITKPyBase.py",
line 2, in <module>

itkBase.LoadModule('ITKPyBase')

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/Release\itkBase.py",
line 103, in LoadModule

if not swigModuleName in sys.modules: module = loader.load(swigModuleName)

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/Release\itkBase.py",
line 214, in load

return imp.load_module(name, fp, pathname, description)

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/lib\ITKPyBasePython.py",
line 30, in <module>

_ITKPyBasePython = swig_import_helper()

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/lib\ITKPyBasePython.py",
line 22, in swig_import_helper

import _ITKPyBasePython

ImportError: No module named _ITKPyBasePython

I've checked and there is an ITKPyBasePython.py in the lib folder.

For trying the ImageType = itk.Image[itk.US, 3], the error I'm getting

>>> imageType = itk.Image[itk.US, 3]

Traceback (most recent call last):

File "<console>", line 1, in <module>

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/Release\itkLazy.py",
line 37, in __getattribute__

itkBase.LoadModule(module, namespace)

File
"C:/Toolkits/ITK-4.5.1/build_x64_VS2008_withLTK/Wrapping/Generators/Python/Release\itkBase.py",
line 42, in LoadModule

swig.__dict__.update(this_module.swig.__dict__)

AttributeError: 'module' object has no attribute 'swig'

There seems to be some issue with swig, but I don't understand how it works
and hence why mine isn't working. Any ideas anyone?

Cheers,

Nicole
