[nipype] nipype import error (nipy labs kalman?)

[John Grif]

Got up this morning and all of a sudden my trusty su neurodebian laptop can't import nipype. 

Error message is below. 

I have no idea what exactly changed since yesterday when everything was hunkydory, but I've tried a couple of things (some debugging attempts; followed by pulling latest; re-installing; doing same with nipy, sympy, and a few other packages; rebooting(!)), and haven't been able to solve this problem so far. 

Any ideas?

This this the error:

In [2]: import nipype

Chars.

It seems that nipy (not nipype) has not been properly build/installed. Do you have cython installed? Did you build and install nipy or just git clone and point to the source directory? "kalman" is a cython module and it has to be build.

I hope this helps.

Best,

Chris
