I simply uninstalled Numpy using:

pip3 uninstall numpy

Then re-installed it:

pip3 install numpy

And somehow this worked.

What you can do is, Create an environment and then install numpy.

Steps : 

virtualenv *your_environment_name*

source *your_environment_name/bin/activate*

sudo pip3 install numpy

If you don't mind about what version you are using, you could try pip install numpy==1.7.2 or another older version. This problem has happened to a few people when trying to install the latest versions of numpy.

If you would really like to use it, I would suggest reinstalling numpy. However, using pip uninstall numpy has been known to not work, so manually going into the Python directory, and Lib, and manually deleting the numpy packages would be your best bet.

If this still doesn't work, you may have to completely delete Python and reinstall it all over again.

The following websites may help you: Numpy build fails with cannot import multiarray, Python ImportError "cannot import name 'multiarray'
