With the Anaconda Distribution installed you should use the conda package manager, not pip:

conda install -c intel scikit-learn=0.21.3

It's also a good idea to start with a new virtual environment to not get constraint by unnecessary dependencies, e.g.

conda create -n myenv -c intel scikit-learn=0.21.3
