[Insight-users] ITK 4.3.1 Python error trying to use Python

[Ariel Hernán Curiale]

Hi,

I found the itk.py class in the directory <ITK-build>/Wrapping/Generators/Python/ then I decided to include this path and  <ITK-build>/lib/ into  PYTHONPATH. Doing this I could read an image, but I don't know if this is the correct setting for the PYTHONPATH. 
If anyone that use ITK and  python could help me it would be great.

Thanks,
