Why do I get this import error when I have the required DLLs?
Question:
from sklearn.feature_extraction.text import CountVectorizer

Answers:
According to this github issue https://github.com/hmmlearn/hmmlearn/issues/87
“The solution is to install mkl.”
conda install mkl
General advice in case like this is to google last two lines of the stack trace, usually you will find a github or similar thread about it.
In my case (this is one of the dependencies used by orange3), I had to follow one of the other suggestions in https://github.com/hmmlearn/hmmlearn/issues/87, which is to install numpy+mkl:
pip install "numpy-1.15.4+mkl-cp37-cp37m-win_amd64.whl"
I had this error but mkl was already installed, uninstalling numpy and scipy and adding conda-forge to my environment’s channels fixed the issue:
conda remove --force numpy scipy
conda config --env --add channels conda-forge
conda install numpy
