[Insight-users] About SimpleITK installation

[Bradley Lowekamp]

Hello Arturo,

I am assuming that you tried downloaded, or easy_installed the SimpleITK binary distribution. The binary distribution for windows is compiled against the official Python distribution for windows. In some cases this has worked with other distributions, but those are not tested nor recommended. So I really can't say what is going on with the binary download and your commercial python distribution. However, we have gotten some reports that the SimpleITK binary distribution worked with EPD on windows though I don't know the specific versions. On MacOSX, the SimpleITK binary is completely incompatible with EPD. 

I would recommend compiling SimpleITK your self against your EPD distribution. More information about compiling SimpleITK can be found here:

http://www.itk.org/Wiki/ITK_Release_4/SimpleITK/GettingStarted#Build_It_Yourself

Lastly, the fact that you are getting some type of Unicode error make me think there may be a problem some were with some type of internationalization error, incompatibility or bug in some component. I'd suggest trying to disable these features if  you are able, and see if the SimpleITK binary will work before you recompile.

Good Luck,
Brad
