Scikitlearn in Jupyter notebook using Anaconda

Question

This is not a duplicate because the linked question does not address how to either locate the required dlls or fix the installation.

I get the following when I try import sklearn v.0.20. I'm using anaconda and both numpy and scipy are up to date.

ImportError: DLL load failed: The specified module could not be found.

Answer 1

EDIT:

I found this thread : https://github.com/numpy/numpy/issues/10965

That mentions a problem related to this.

So it seems the guy there solved his problem by removing both numpy and scipy and reinstalling them. There is a chance your version of scipy for some reason is linked against a MLK version of numpy and that's the reason things don't work.

END OF EDIT

I checked around for your problem and it seems that this is related to the version of numpy you have.

To fix the problem you should install numpy-MLK which is a version on numpy linked against Intel's Math Kernel Library.

You can find it here: https://pypi.org/project/numpy-mkl/

Just remember to first remove the already existing numpy package.

You can find more info here:
