I have no idea what's going on here. The skimage module actually works well.

This is the new error.

Try opening a python shell and just running this line.

>>> from skimage import transform as tf

What is the output? If it fails, then there is a problem with your skimage installation. How did you install it? What Windows python installation are you using?

[Yu Peng]

This goes smoothly, no error. I'm using the newest skimage package, Python 2.7.9,windows 8, I also tried to use Ubuntu Linux to install sima in my Linux system, it works well.

[Yu Peng]

I installed sima using pip, as well as downloading the sima from website and use cmd Python install. Both installed it successfully.
I think the problem may be the skimage package lacking some subfunctions. I reinstalled it once but did not work.

[Patrick Kaifosh]

This is confusing, because the line in sima that is triggering the sklearn error is:

>>> from skimage import transform as tf

But you tell me that when you run this line separately, then there are no problems. Is it possible that you have multiple versions of sklearn installed? Can you use pdb to check which version of sklearn is being used by sima, and make sure that is the same one as works properly when you run the import command from command line?

Are you using Anaconda, WinPython, Python(x,y), or just plain CPython on Windows?
