KRG can predict only 1 output, so if you have multiple outputs you have to train a surrogate for each output.

Hi, Concerning multi fidelity data, you have some examples in the documentation: https://smt.readthedocs.io/en/stable/_src_docs/applications/mfk.html and in the notebooks https://github.com/SMTorg/smt/blob/master/tutorial/SMT_MFK_tutorial.ipynb https://github.com/SMTorg/smt/blob/master/tutorial/SMT_MFK_Noise.ipynb Best Nathalie
