0.4.1 ; installing MKL to use STFT on CPU

Hello everyone

I updated from 0.4.0 to 0.4.1 and now STFT is not working anymore on CPU because I miss the package MKL. I run on python 3.5.1 and MacOS.

When I tried
" pip3 install mkl "

terminal returns
" Collecting mkl
Could not find a version that satisfies the requirement mkl (from versions: )
No matching distribution found for mkl "

Looking online I didn’t find solutions so far, and I do not want to use conda.

Please, did anyone find a solution ?
