LazyITKModule' object has no attribute 'AnalyzeImageIO'

Question

from medpy.io import load
import SimpleITK
import vtk

image_data, image_header = load('/Users/N01-T2.mha')
print image_data.shape

And the error is:

Traceback (most recent call last):

'LazyITKModule' object has no attribute 'AnalyzeImageIO'

I want to deal with .mha image, but it doesn't work. I have installed medpy, itk and vtk.

I have searched on Google, but there is not related answer to this problem.

Does the same error occur without the import SimpleITK line? I don't think that is relevant to producing this error.

ITK for Python and SimpleITK are two separate Python packages which provide different interfaces to ITK. The error you are seeing is lated to ITK for Python, or the itk package on PyPi. Where did you itk install come from. Can you run a simple program like this, with your install?

#!/usr/bin/env python
import itk
pixelType = itk.UC
imageType = itk.Image[pixelType, 2]
readerType = itk.ImageFileReader[imageType]
