This pull request remove the dependency on sklearn when loading datasets or emulators. Turns out the Emulator class only needs sklearn for sklearn.metrics.r2_score. As sklearn is a pretty heavy dependency (26 mb download alone), I opted for just copy pasting (retaining copyright notices) the required code and to load it when sklearn can't be found.
