That is classical resource for GP, but using Matlab. I'm looking for something practical using Python.

I haven't used it, but you may want to explore GPy [0] if you haven't already.

I never understood what is the difference between GPy and GP in sklearn. I'm using the latter, but still do not understand most of parameters that go into this model.
