Hi Brad,
I set the PATH and PYTHONPATH as follows
set PATH=C:\CAMH\ITK\lib\ITK-4.2\Python
set PYTHONPATH=C:\CAMH\ITK\lib\ITK-4.2\Python
which is where the .pyd files are. However, I still get the same error after issuing the following commands in python
import itk
image_type = itk.Image[itk.F, 3]
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\CAMH\ITK\lib\ITK-4.2\Python\itkLazy.py", line 37, in __getattribute__
itkBase.LoadModule(module, namespace)
File "C:\CAMH\ITK\lib\ITK-4.2\Python\itkBase.py", line 95, in LoadModule
LoadModule(dep, namespace)

if not swigModuleName in sys.modules: module = loader.load(swigModuleName)
File "C:\CAMH\ITK\lib\ITK-4.2\Python\itkBase.py", line 214, in load
return imp.load_module(name, fp, pathname, description)
File "C:\CAMH\ITK\lib\ITK-4.2\Python\ITKCommonPython.py", line 30, in <module>
_ITKCommonPython = swig_import_helper()
File "C:\CAMH\ITK\lib\ITK-4.2\Python\ITKCommonPython.py", line 26, in swig_import_helper
_mod = imp.load_module('_ITKCommonPython', fp, pathname, description)
ImportError: DLL load failed: The specified module could not be found.
Is there anything else I need to add to my PATH or PYTHONPATH environment variables, or have I missed setting another
environment variable?
Cheers
Peter

There should be a bunch of pyd files in that directory. The pyd extension is used for python C libraries[1], and should be
included in your path. There should be a pyd file for each ITK module.

Hi Matt,
Thanks for getting back to me. This is where I am a tad confused.
In the directories under 'C:\CAMH\ITK' there is only a single DLL in directory C:\CAMH\ITK\bin named ITKCommon-4.2.dll.
There are 76 files in directory C:\CAMH\ITK\lib with the extension .lib
The only file named _ITKCommonPython is in the directory C:\CAMH\ITK\lib\ITK-4.2\Python and has an extension .pyd.
Cheers
Peter
