[Insight-users] Python Wrappers - WinXP - Solved

[Peter M. Bloomfield]

Hi,

I managde to get the python wrapping working in the end. I had to have the following on the PATH and PYTHONPATH environment 
variables, where C:\CAMH\ITK is the install directory

	PATH - added C:\CAMH\ITK\bin
	PYTHONPATH - added C:\CAMH\ITK\lib\ITK-4.2\Python

I am not quite sure what the effect of adding C:\CAMH\ITK\bin to PATH is as there are only two files in the directory, 
ITKCommon-4.2.dll and itkTestDriver.exe

The bottom line is that I can access itk from within python.

Hi,

I am experiencing a problem with python wrapping. I have the following on a 32-bit WinXP machine
	Visual Studio 9 2008
	ITK V4.2.1
	Python 2.7.2

I have selected 'ITK_WRAP_PYTHON' and 'BUILD_SHARED_LIBS' and set 'CMAKE_INSTALL_PREFIX' to C:\CAMH\ITK within cmake, and all 
compiles and installs without error in VS 2008.

I have set a PYTHONPATH to include both
	C:\CAMH\ITK\lib\ITK-4.2\Python
	C:\CAMH\ITK\lib
though I am not sure if I have these correct. I can import itk from within python, but get an error when issuing the command
	image_type = itk.Image[itk.F, 3]
as shown below.

	    _mod = imp.load_module('_ITKCommonPython', fp, pathname, description)
	ImportError: DLL load failed: The specified module could not be found.

Can anyone point me in the right direction to get the itk python wrapping working,

Many thanks

Peter
