This PR fixes #5306 by adding a catch for the calculation of
R^2during metric calculation. When there is less than two rows of data used for the calculation ofR^2, the returned value becomes-Infinity, whereas it should be returningNaN.An example of this behavior in another ML framework is in scikit-learn, in the following lines:
