In all of my scripts where I use packages dependent on scipy (such as sklearn and statsmodels) I receive this ImportError.
I uninstalled Anaconda and installed a fresh version of Anaconda (the latest 2019.03 for Windows 10). I've also tried creating separate environment and installing scipy, numpy, sklearn independently and this also did not work.
from sklearn import preprocessing
