Difference between scikit-learn and sklearn
You might need to reinstall numpy. It doesn't seem to have installed correctly.
sklearn is how you type the scikit-learn name in python.
Also, try running the standard tests in scikit-learn and check the output. You will have detailed error information there.
Do you have nosetests installed? Try: nosetests -v sklearn. You type this in bash, not in the python interpreter.
On OS X 10.11.6 and python 2.7.10 I need to import from sklearn  manifold. 
I have numpy 1.8 Orc1, scipy .13 Ob1 and scikit-learn 0.17.1 installed.
I used pip to install sklearn(0.0), but when I try to import from sklearn manifold I get the following: 

Traceback (most recent call last):   File "", line 1, in

  "/Library/Python/2.7/site-packages/sklearn/init.py", line 57, in

What is the difference between scikit-learn and sklearn?  Also, 
I cant import scikit-learn because of a syntax error
