Problem:
catboost version: 1.0.6
Operating System: Windows
CPU: Intel

When using the catboost.get_object_importance function in R, I get the following error:
Non-Multiclassification and Non-MultiTarget compatible metric (RMSEWithUncertainty) specified for a multidimensional model

which is the same as already described here for get_feature_importance in R: #1438

This bug has already been fixed so I suppose the get_object_importance one should he fixable too.
