It seems that scikit-learn has not been built correctly.

If you have installed scikit-learn from source, please do not forget
to build the package before using it: run `python setup.py install` or
`make` in the source directory.

If you have used an installer, please check that it is suited for your
Python version, your operating system and your platform.

Answer 1

As you can see in your errors: ImportError: No module named _check_build in that directory it has .c file and it never compiled.

If you check this link you will see many parts of scikit-learn has been written in C.

So for installing this kind of packages , you need to install python-dev package in your system.

python-dev package will install many C headers like python.h.

So install python-dev package in your system and then remove and install scikit-learn package again.
