After updateing my python version and packages this error started when I tried to import sklearn. It only happens in Python 32-bits, with the 64-bits version, everthing work.

with Python 3.8 (32-bits)

import sklearn No erros!

Steps/Code to Reproduce

python 3.8 (32-bits) and scikit-learn 0.22 import sklearn

with python 3.8 (64-bits) everthing works fine.

I had same problem, now its working after installing after installing latest Microsoft Visual C++ re-distributable. Link: https://support.microsoft.com/en-in/help/2977003/the-latest-supported-visual-c-downloads

Hi @jeremiedbb , I have quite the same configuration Windows (64 bits with 32 bits compat, x86_64) and I installed Python direct from https://www.python.org/downloads/ and scikit-learn from (pip install scikit-learn).

Actually I just found the problem, somehow looks like the new version of scikit-learn (0.22) accept my MS C++ 2017 version during installation but don’t work with it. I found this out when I tried to install version 0.21 and got an error that I didn’t have the correct version of VS C++ tool. It started to work after I installed the MS C++ 2019. Maybe there is a problem with the MS C++ version check.
