Fix ValueError: Unknown label type: 'continuous' In scikit ...

numpy - LogisticRegression: Unknown label type: 'continuous' … That's generally true, but sometimes you want to benefit from Sigmoid mapping the output to [0,1] during optimization. If you use least squares on a given output range, while training, your model will be penalized for extrapolating, e.g., if it predicts 1.2 for some sample, it would be penalized the same way as for predicting 0.8.This constraint might distract the optimization from the objective.
