why mode in scipy.stats do not work

Question

i want to get mode of a list, so i try to use mode function in scipy, but i get the following error,

from scipy import stats

a = np.array([[6, 8, 3, 0],
...               [3, 2, 1, 7],
...               [8, 1, 8, 4],
...               [5, 3, 0, 5],
...               [4, 7, 5, 9]])

mode(a)

error message:

---------------------------------------------------------------------------

ImportError: DLL load failed: can not find module.

what's the problem here ? although i can import statistics, and use mode function of that, i also want to make it clear why scipy.stats can not be used ? is there some changes in python 3.4 for that moudle ?

It looks like you are running this code under windows. How did you install the scipy package. If you are just trying out the scipy package under windows, it is much easier to work with anaconda installation. (https://docs.continuum.io/)

List of packages (includes scipy too): (https://docs.continuum.io/anaconda/pkg-docs)

The package manager comes with all the modules (along with necessary libraries included) and works for all the platforms and it is a breeze to make it work on windows.

I personally encountered lot of issues while installing numpy, scipy, pandas on windows, therefore i switched to Anaconda.
