## Summary As commented in PR !5052 [here](https://github.com/microsoft/LightGBM/pull/5052#issuecomment-1065948234) the Sklearn Regressor `LGBMModel` method `fit` process metrics from params using `_separate_metrics_list` and `_concat_params_metrics`

If argument `feature_names` in function `eli5.show_weights()` is `pandas.core.indexes.base.Index` raises an `TypeError: Unexpected feature_names type`. ## To reproduce ```python import eli5 from eli5.sklearn import PermutationImportance from sklearn.ensemble import RandomForestRegressor from sklearn.model_selection...
